Preface

This book is the first comprehensive guide to the frogs and reptiles of the Murray–Darling Basin: a massive depression with an area of 1 059 000 km2 that spans most of New South Wales, northern Victoria, the Australian Capital Territory, the lower third of Queensland and the south-eastern corner of South Australia. It examines the 66 species of frogs and 244 reptiles that are found through the 22 smaller catchments that make up the greater Murray–Darling Basin. Each catchment is unique and varies in climate, topography, vegetation and fauna. The guide has been produced to allow readers to identify the frogs, freshwater turtles, lizards and snakes of the region, using descriptive species accounts, photographs and distribution maps. The species accounts provide descriptions of morphological features of each animal and includes notes on their habitat, behaviour, conservation status and distribution. The common and scientific names used in the book follow: • Clulow S, Swan MG (2018), A Complete Guide to Frogs of Australia. Australian Geographic Holdings, Sydney • Wilson SK, Swan G (2017) A Complete Guide to Reptiles of Australia. 5th edn. Reed New Holland, Sydney.

The Murray–Darling Basin is at the forefront of many Australians’ minds as an area of much environmental concern involving government organisations, farmers, politicians, Indigenous Australians, tourist guides and recreational users. The management of water in the system remains the greatest area of debate focusing on availability and quality. The natural flow cycles of the system have been altered over time to improve agriculture but it has come at a cost to the environment. Frogs in particular are affected by increased salinity, pollutants and the reduction or alteration of wetlands. Reptiles are at risk from changes to habitat by overgrazing, clearing and controlled burning. Also invasive species preying on their eggs and juveniles, resulting in low recruitment. General information and promotional material on the herpetofauna of this very important region of Australia is limited and suggests the high number of species it contains is greatly under appreciated. Hopefully this publication will lead to a much better understanding of the diversity of the frogs and reptiles in the Murray– Darling Basin and to more concerted efforts for their long-term conservation.

Introduction An overview of the Murray–Darling Basin Over 300 million years ago during the Carboniferous period, Australia collided with what are now parts of South America and New Zealand. The entire region was uplifted and created the Eastern Highlands or Great Dividing Range. It is Australia’s most significant mountain range and the third longest land-based range in the world. It extends more than 3500  km from the north-eastern tip of Queensland, down the entire length of the eastern coastline through New South Wales, into Victoria and eventually ends on the central plain at the Grampians in Western Victoria. The width of the range varies from ~160  km to over 300 km. The highest areas of the Australian continent are in the Great Dividing Range and it was a formidable barrier to westward migration for European settlers until 1813. There is a wide variety of vegetation throughout its length, from rainforest and

wet sclerophyll forest to woodlands and alpine grasslands that provide important habitat for a great diversity of wildlife. Rivers that originate in the Great Dividing Range run east into the Pacific Ocean or west into the Murray–Darling Basin (MDB): an area of 1  059  000  km2 or 14% of Australia’s total land area. The MDB is a massive depression that spans most of New South Wales, Northern Victoria, the Australian Capital Territory, the lower third of Queensland and the south-eastern corner of South Australia. The area was first explored by European pioneers Hamilton H. Hume and William H. Hovell in 1824. Five years later, Charles Sturt navigated down the Murrumbidgee River to encounter the Murray River and named it after Sir George Murray when his team reached the connection with the Darling River. An extract of an account of the journey from Sturt’s diary, published in London in 1833, was typical for the time.

‘The plains were open to the horizon. Views as boundless as the ocean. No timber but here and there a stunted gum or a gloomy cypress. Neither bird nor beast inhabited these lonely regions over which the silence of the grave seemed to reign.’ But there were Indigenous Australians living along the river, as they had been for 40  000 years, and in the World Heritage Willandra Lakes and Mungo National Park north-east of Wentworth and north of Mildura and Balranald. The Mungo region was recognised in 1981 as an important geological area and for its history of Indigenous occupation. The rich resources of the rivers and the adjacent lands maintained a denser population and more settled lifestyle than could be supported in more arid areas. 2

After this early exploration period the development of the agricultural districts of inland New South Wales began and today the MDB is an area of great productivity for agriculture, logging and mining. It is Australia’s most important agricultural region, containing over 40% of Australian farms that produce wool, cotton, wheat, sheep, cattle, dairy produce, rice, oil-seed, wine, fruit and vegetables for both domestic and international markets. Over two million people live in the Murray–Darling Basin, from the national capital Canberra to many of Australia’s major inland towns including Toowoomba, Tamworth, Dubbo, Orange, Wagga Wagga, Albury-Wodonga, Shepparton and Bendigo. The climate is subtropical in the north, semi-arid in the west and mostly temperate in the south. Water is the most valuable resource in the Murray–Darling river system, with the majority of it flowing in from along the southern and eastern rim. About 85% of the vast catchment has almost no regular run-off into rivers. The MDB is the largest and most complex river system in Australia and contains Australia’s three longest rivers: the Murray (2508   km), Murrumbidgee (1690  km) and the Darling/Barwon river system (2740  km). All the rivers have very low gradients over most of their length, causing them to flow slowly. Water quality is paramount and threats to water quality include high salinity because large quantities of salt occur naturally. Floodplains are an important feature of the Basin because floodplain

vegetation uses groundwater in the soil profile and prevents water and salts rising to the surface or being transported to the river. Increased salinity into the Basin’s water resources is often increased by activities such as irrigation development and land clearing. Major threats to the flora and fauna of the MDB include the quantity of water removed from the river systems, habitat loss and alteration, exotic invasive species and diseases.

The Murray–Darling Basin catchments The large depression of the MDB receives all the water from inland-flowing streams, creeks and rivers. Water from the northern catchment flows into the Darling River and water from the southern catchment flows into the Murray River. There are 22 major catchments (or sub-basins) within the Murray–Darling Basin. Although most of the major rivers flow into either the Darling or the Murray, some, such as the 3

Paroo, Lachlan and Wimmera, terminate in wetlands or marshes. The water from these rivers only reaches the Darling or the Murray in years of extremely heavy rainfall. The topography and vegetation can vary between the different catchments, with floodplain forests, woodlands and

wetlands requiring different amounts of water throughout the year. Water management in rivers with monitored flows have affected the type, diversity and nature of plant communities along the rivers and floodplains. This has resulted in a decline of species such as River Red Gums, Black Box and Lignum shrublands.

INTRODUCTION

Paroo Catchment

The Paroo River catchment is in the northwest corner of the MDB and spreads roughly equally across Queensland and northern New South Wales. Annual rainfall is low, with averages of 200–400 mm across the catchment. Most of the rain falls in the northern area and occurs in summer and autumn and has a very high evaporation rate. The Paroo River is 600  km long and contributes only 2% of the total water to the system. The headwaters are at an elevation of 330  m in the Warrego Range, west of Charleville. From there it flows across semi-arid plains with little surface water being mostly a series of waterholes, lakes and wetlands, some which are permanently wet. The Paroo River tributaries include the Beechal, Yowan and Qulberry, and part of the Cuttaburra Creek, and it is the last freeflowing river in the Murray–Darling Basin. The river terminates on the floodplains south of the town of Wanaaring in the top north-west corner of New South Wales. In very wet years the waters of the Paroo will flow to reach the Darling River, between the towns of Louth and Wilcannia. The landscape consists of undulating red soil plains with mulga scrub and shrubland. Eucalypt and gidgee occur along the waterways with the dominant eucalypt species being River Red Gum, Coolabah and Poplar Box. In the lower reaches of the catchment many types of wetland vegetation are found, including Black Box, River Cooba and a variety of grasses. Significant wetlands occur throughout the catchment including Currawinya Lakes, Nocoleche Nature Reserve and Peery Lake. River flow is

important to these habitats and critical to retaining a good diversity of wildlife. There are 17 frog species and 76 reptile species recorded from the Paroo River Catchment. The conditions of the catchment are semi-arid with low rainfall, so about half the frog species are burrowing frogs. Other types of frogs are dependent on creek lines, semi-permanent waterholes, lakes and wetlands for survival. Three species of freshwater turtles occur around waterways and there is good representation from each lizard family. Blind snakes, venomous land snakes and pythons are also present. Some arid-adapted species that occur only in the Paroo Catchment are the Eastern Deserts Fat-tailed Gecko (Diplodactylus ameyi), Variable Fat-tailed Gecko (Diplodactylus conspicillatus),

Warrego Catchment

The Warrego catchment is located in the north-west of the Murray–Darling Basin, with most of its area in Queensland and the remainder in New South Wales. Annual rainfall is low, ranging from 500 mm in the north-east to 250  mm on the plains of the lower catchment. Most of the rain falls in the north, mainly in summer and autumn and evaporation in the region is high. The Warrego River is 1380  km long and its headwaters are around 600  m in the Carnarvon Range near Tambo in 6

South-East Queensland. It flows south across semi-arid plains, being joined by 37 intermittent tributaries. In years of heavy rainfall it joins up with the Darling River downstream from Bourke. Sometimes water from Cuttaburra Creek enters the lower reaches of the Paroo River. The towns of Augathella, Charleville, Wyandra and Cunnamulla are located on the banks of the Warrego River. The predominant land use is low-intensity grazing of sheep and cattle as the river’s flow is much too inconsistent to establish irrigated crops. Generally, groundwater resources within the region are of poor quality and are not suitable for large-scale irrigation. Vegetation varies from clay soil grasslands to saltbush with predominantly mulga shrubland and areas of brigalow in the north. Waterways support cypress pine woodlands and gidgee along floodplains. In the lower reaches of the catchment, River Red Gum, Coolibah, cane grass, Lignum and River Cooba grow along channels and in wetlands. The Warrego River waterholes are a string of large permanent and semipermanent waterholes which are usually flooded seasonally. There are ~300  000 ha of wetlands in the Warrego Catchment

INTRODUCTION

consisting of saline lakes, Lignum swamps, flood channels, freshwater lakes, claypans and water holes. Twelve wetlands are considered of national significance including the Yantabulla Swamp and the Warrego River waterholes. Large populations of waterbirds inhabit the waterholes during periods of high flows and they are also important Indigenous cultural sites. There are 19 frog species and 71 reptile species recorded from the Warrego River Catchment. Much of the area consists of semi-arid plains with low annual rainfall. The clay soil grasslands and mulga shrubland provide important habitat for frogs and reptiles. Burrowing frogs are well represented along with other frog species and three freshwater turtle species that are

mostly dependent upon semi-permanent and permanent waterways. Each of the five lizard families occur here and also blind snakes, pythons and venomous land snakes. Most species are wide-ranging throughout the catchment.

Condamine-Balonne Catchment

The Condamine–Balonne rivers catchment is one of the largest catchments in the MDB and home to almost 10% of the human population of the Basin. Most of the catchment is located in Queensland, with less than 20% extending into northern New South Wales. The Condamine River, with a length of 1195  km, rises in the Great Dividing Range at 1400 m then flows northwest to Dalby and Chinchilla. From there it continues south-west to the plains where it

joins Dogwood Creek and becomes the Balonne River near Surat. The Maranoa River rises in the Carnarvon National Park and flows south-east through the town of Mitchell before joining the Balonne River at Lake Kajarabie (Beardmore Dam) just upstream of St George. Beyond this point the Balonne River becomes a network of channels, waterholes and floodplains that form the Narran, Bokhara, Ballandool and Culgoa rivers. In times of very high flow, the Bokhara and Culgoa rivers flow into the Barwon–Darling River downstream of Brewarrina. The major towns in the catchment are Warwick, Toowoomba, Dalby, Roma and St George. This region has enormous agricultural diversity, with a wide range of winter and summer crops produced on the Darling Downs, as well as very large cotton production areas in the west. The landscape of the Condamine–Balonne catchment is diverse, with tablelands of the dividing range in the east, gorges in the north-west and semi-arid plains in the south-west. In the eastern part of the catchment the annual average rainfall is 600–800 mm and the floodplains of the south-west receive an average 300–500  mm. Rainfall throughout the catchment is heaviest over summer and 8

the climate is subtropical. Evaporation rates in the south-west of the catchment are very high. Wetlands of national importance include the Great Artesian Basin Springs, Lake Broadwater, The Gums Lagoon, the Culgoa River Floodplain and Dalrymple and Blackfellow creeks. The Condamine–Balonne Catchment has a diverse herpetofauna, with 43 frog species and 147 reptile species. The catchment’s extensive floodplains have important vegetation communities, including brigalow–gidgee woodland and shrubland, which provide habitat for a large range of frogs and reptiles. The western slopes of the Great Dividing Range are part of the MDB and have areas of montane subtropical rainforest, which are occupied by some rainforest

herpetofauna. In the floodplains and woodlands habitat, species such as the Striped Burrowing Frog (Cyclorana alboguttata), Yakka Skink (Egernia rugosa) and Pale-headed Snake (Hoplocephalus bitorquatus) may be observed.

Moonie Catchment

The Moonie River Catchment is the smallest of the northern catchments, with most of the area in Queensland. The Moonie River flows from an altitude of 350 m at its source on the Southern Downs across south-west Queensland, through a slightly undulating landscape into northern New South Wales. It is joined by 13 minor tributaries before merging with the Barwon River downstream of Mungindi. It is a simple channel system of unconnected waterholes throughout most of the year.

However, there are more than 100 wetlands with significant habitat along the Moonie River floodplain. The region is semi-arid with a warm to hot climate and an average annual rainfall of 500–600   mm. Rainfall can vary significantly from year to year, resulting in irregular and infrequent river flows. The catchment has been heavily cleared and impacted by agricultural development with eroded riverbanks and riparian zones. Vegetation includes remnant areas of brigalow scrub, mixed eucalypt woodland areas and open grasslands. It is sparsely populated, with less than 0.1% of the people in the Basin living in the region. Towns include Moonie and Thallon, where a weir was built over the river in 1959 to supply town water. Small to medium weirs are dispersed along the river for irrigation purposes, predominantly for cotton. Beef cattle are the major source of income and employment in the region though a small area of the catchment is irrigated, mainly for cotton or pasture. Cereal crops and plantation forestry also contribute to the regional economy. The Moonie River Catchment may be small, but it still has 22 frog species and 68 reptile species. It is part of the Southern

Brigalow Belt: a region where ~60% of the original vegetation has been cleared over the last 200 years. This has resulted in plant and animal communities, including several species of endemic reptiles, becoming threatened. The catchment contains important habitat for species such as the Brigalow Scaly-foot (Paradelma orientalis), Golden-tailed Gecko (Strophurus taenicauda) and Dunmall’s Snake (Furina dunmalli).

Border Rivers Catchment

The Border Rivers Catchment is diverse and consists of a group of rivers in the north-eastern region of the New South Wales and Queensland border. The rivers of the catchment rise on the western slopes of the Great Dividing Range at heights of 1500  m and run westwards, gradually 10

merging with one another to become the Barwon River on the floodplains upstream of Mungindi. Major tributaries are the Macintyre River, Dumaresq River, Severn River (NSW), Severn River (Qld), Macintyre Brook and Weir River. A 450 km section of the Dumaresq, Macintyre and the Barwon rivers form the border between Queensland and New South Wales. The eastern part of the catchment, where most of the rivers rise, has an annual average rainfall of 800–1100  mm, compared with the semi-arid floodplains to the west that receive an average of around 500  mm. Rainfall throughout the catchment is heaviest in summer and the climate is described as subtropical to temperate at higher altitudes. The catchment is home to ~2.5% of the human population of the Basin and major towns include Goondiwindi, Stanthorpe, Tenterfield, Glen Innes and Inverell. Agriculture is well established throughout the catchment and is a diverse primary industry. The larger towns and agriculture are the main users of water and there are many small weirs and regulators throughout the catchment that supply water for domestic and stock use. Dams were built in the 1960s and 1970s for flood mitigation and irrigation water supply to

the plains. Since that time, river flows in the catchment have been highly regulated. Native vegetation communities in the Border Rivers Catchment are largely determined by a combination of rainfall and temperature. Woodlands and forests are the most common, but heaths, shrublands, swamps, grasslands and rainforests are all represented. Rivers and wetlands of the region provide important habitat for frogs and include the nationally significant Morella Watercourse, Boobera Lagoon and Pungbougal Lagoon located on the Macintyre River floodplain, and are considered among the most important sites for Indigenous people in eastern Australia. The Border Rivers Catchment has 36 species of frogs and 101 species of reptiles with several areas of herpetological interest, such as the massive granite outcrops at Girraween. This habitat contains many species of frogs and reptiles including the New England Tree Frog (Litoria subglandulosa), Bell’s Turtle (Wollumbinia bellii), Granite Belt Leaftailed Gecko (Saltuarius wyberba), Granite Belt Thick-tailed Gecko (Uvidicolus sphyrurus) and Stephen’s Banded Snake (Hoplocephalus stephensi).

Gwydir Catchment

The Gwydir River rises at ~1200  m west of Armidale on the New England Tablelands in the Great Dividing Range of New South Wales. It flows north-west for 480  km, passing through steep valleys and then down the north-western slopes onto almost completely flat alluvial floodplains. The Gwydir region floodplains include large expanses of wetland vegetation supported

by natural channels, semi-permanent wetlands and swamps that have a high conservation value. Widespread inundation of the catchment’s wetlands depends primarily on floodwaters originating in the upper catchment. Downstream of Moree, the Gwydir River diverges at the Gwydir Wetlands into the Gingham Watercourse and the lower Gwydir (or Big Leather) Watercourse. The Gwydir Wetlands State Conservation Area is a significant, semi-permanent, wetlands of over 100  000  ha in north-eastern New South Wales. It provides important habitat for threatened animal and plant species. The lower half of the catchment has numerous anabranches and effluents, the most significant being the Mehi River and Moomin Creek to the south, and the Carole–Gil Gil Creek system to the north. The latter creek system joins with the southern effluents of the Border Rivers. Several of the branching streams from the Gwydir enter the Barwon River between Collymongle and north of Collarenebri. The Gwydir Catchment is home to ~1.3% of the human population of the Basin and major towns include Moree, Uralla, Guyra, Bingarra and Wrialda. Water use is largely from irrigated agriculture, urban water supply, stock and mining. The Gwydir River is regulated by several weirs: most notable is the Copeton Dam. Regulation and irrigation supply have resulted in more frequent low flows to the river system and more water flowing through regulated waterways to the Barwon River. The Gwydir Catchment has a variety of habitats from high altitude forests in the east to open forest and woodlands on the slopes, to scrublands and grasslands on 12

the floodplains. Much of the natural environment is fragmented due to agricultural development. The eastern half of the catchment has an annual average rainfall of 700–900  mm while on the floodplains of the western portion it ranges from 450 to 550 mm. Rainfall throughout the catchment is heaviest over summer and the climate is described as subhumid and subtropical. There are 35 species of frogs and 81 species of reptiles recorded from Gwydir Catchment. Some typical species in this region include the Broad-palmed Frog (Litoria latopalmata), Salmon-striped Frog (Limnodynastes salmini), Ocellated Velvet Gecko (Oedura monilis), Southern Spotted Velvet Gecko (Oedura tryoni), Leaden Delma (Delma plebeia), Black-necked

Namoi Catchment

The headwaters of the Namoi River and several of its main tributaries are located at ~1500  m above sea level in the Great Dividing Range of north-eastern NSW. In these higher areas there are steep, forested ranges and elevated tablelands where annual rainfall averages 800–1000 mm. The catchment is diverse in climate and landscape, ranging from cool with high rainfall areas in the east to semi-arid, low rainfall areas on extensive riverine plains in the west.

The Namoi River is 700  km long being joined by the MacDonald River north-east of Manilla. Many of the Namoi’s tributaries meet the river in the foothills of the ranges, including the Peel River, which flows through the city of Tamworth. Beyond the town of Gunnedah, the Namoi River is the main waterway flowing west. The catchment is bounded by the Nandewar Ranges and Mount Kaputar in the north and the Liverpool and Warrumbungle Ranges in the south. Major towns include Tamworth, Gunnedah and Narrabri. Downstream of Narrabri, the catchment is flat floodplain country and supports a wide range of aquatic habitats including large areas of billabong wetlands. These wetlands require periodic flooding to maintain good condition. The annual rainfall in this area is on average only ~400 mm. The Namoi River continues flowing west across the floodplains, which undergo partial flooding. At the western end of the valley, near the town of Walgett, several small anabranches break away from the river and carry water through to the Barwon River during periods of high flows. The Namoi catchment is an important water supply for downstream environments in the Barwon and Darling rivers. The Namoi Catchment has 36 frog species and 78 reptile species. Important areas of herpetological interest include Mount Kaputar and the Pilliga Scrub (the largest dry sclerophyll forest west of the Great Dividing Range in New South Wales). The Pilliga Scrub contains a variety of herpetofauna and has been the subject of numerous surveys, which have recorded 14 frog species and 13

at the confluence of the Macintyre and Weir rivers to where the Barwon meets the Culgoa River. From there the river channel becomes the Darling River and the Bar won–Darling system extends downstream to the Menindee Lakes. The Barwon–Darling region has a semi-arid climate and rainfall is low throughout the year, peaking during summer, with an annual average of 330 mm. The catchment of the Barwon–Darling covers ~13% of the MDB but only generates ~2.8% of the flow in the Basin. The Barwon–Darling is only regulated by some low-level weirs near townships, but many of the tributaries of the system are highly regulated. The Barwon–Darling corridor connects all the rivers, lakes and wetlands in the northern Basin to the southern Basin through the lower Darling River. The river system provides moist habitat during dry periods and corridors for wildlife in this semi-arid region. Many billabongs and lagoons occur along this corridor, as well as lakes and wetlands on the floodplains. Almost 30% of the catchment area remains as native vegetation. Riverine woodland dominated by River Red Gum is the most common vegetation community along the banks and associated wetlands of the Barwon–Darling river system. Upstream of

INTRODUCTION

Brewarrina are large areas of open semiarid eucalypt woodlands. The Darling River flows south-west within a deeply incised channel towards Wilcannia. Here Belah woodlands occur on the floodplain, featuring Rosewood, Sugarwood and Wilga. Below Wilcannia the Darling River reaches the Menindee Lakes at the artificial storage of Lake Wetherell. Beyond this point the catchment becomes the Lower Darling. There a several small towns in the region: Collarenebri, Walgett, Brewarrina, Bourke, Cobar and Wilcannia. The major land use is dryland grazing of cattle for beef and sheep for wool. A small area of land is irrigated and mainly supports cotton production and also mining activities in Cobar and Lightning Ridge. Barwon-Darling Catchment has 19 species of frogs and 69 reptile species. There are five large, dangerously venomous, snakes in this region including an old record for the Inland Taipan (Oxyuranus microlepidotus) from Tindaree, New South Wales. Other species from this catchment include the Eastern Water-holding Frog (Cyclorana platycephala), Central-netted Dragon (Ctenophorus nuchalis) and Darkspined Blind Snake (Anilios bicolor).

Macquarie-Castlereagh Catchment

The Macquarie-Castlereagh Catchment in central New South Wales covers ~7% of the Basin and has three major rivers: the Castlereagh, Macquarie and Bogan. The Castlereagh River rises in the volcanic

remnants that shape the Warrumbungle Ranges, west of Coonabarabran in northern New South Wales and meets the Macquarie River a little upstream of where the Macquarie meets the Barwon River. The Macquarie River rises in the Great Dividing Range near Bathurst and flows north-west through foothills and slopes past Wellington and towards Dubbo. The Bogan River rises in the Harvey Ranges near Parkes in centralwest New South Wales and flows northwest past Nyngan to meet the Barwon River upstream of Bourke. The catchments of the Castlereagh and Macquarie rivers support a diverse range of ecosystems, from forest, woodlands and wetlands to grasslands, in temperate and semi-arid environments. Important wetland environments in the catchment include the Macquarie Marshes, which are home to many threatened species. As the waterways approach the Barwon River, the interconnected streams, as well as lagoons and channels, support extensive flood-dependent woodlands and grasslands. The Castlereagh and Macquarie catchments are typical of most Basin catchments, rising in or near the Great Dividing Range where most of the streamflow originates at high 16

altitude up to 1300 m and annual average rainfall is above 600 mm. Agriculture in the catchment is diverse, from horticulture in the east, dryland grazing and cropping on the slopes, to irrigated cropping and extensive grazing in the west. Major towns include Coonabarabran, Coonamble, Bathurst, Orange and Dubbo. The Macquarie-Castlereagh Catchment has 26 frog species and 84 reptile species. A significant habitat for frogs and reptiles in this catchment is the Macquarie Marshes, with one survey of the area recording 12 frog, three freshwater turtle, 27 lizards and 13 snake species. The very attractive Crucifix Frog (Notaden bennettii) occurs in this area and also a large population of the Red-bellied Black Snake (Pseudechis porphyriacus). The Macquarie

INTRODUCTION

Marshes semi-permanent wetland vegetation has decreased significantly in size since the 1990s.

Lower Darling Catchment

The lower Darling River flows 530 km from the Menindee Lakes to its junction with the Murray River at Wentworth. The catchment is located on the semi-arid plains of southwestern New South Wales and nearly all the water flowing through the lower Darling comes from the rivers of southern Queensland and northern New South Wales. Most of the landscape is relatively flat and receives an average annual rainfall of less than 300  mm. Due to low rainfall and high summer temperatures the area has very high evaporation rates. Menindee Lakes at the head of the Lower Darling Catchment is a natural system of seven large lakes that were modified for water storage in the 1960s. The flow rate in the Darling River has been reduced so dramatically that it no longer flows and is now a dry riverbed. This is a direct result of water being taken from the upper catchments of the Barwon–Darling river system. The Menindee Lakes provide important habitat for wildlife including frogs and reptiles.

Below the Menindee Lakes, the river has two large and distinct channels: its main channel, the lower Darling River, and its ancestral channel, the Great Darling Anabranch. This anabranch and its associated lakes are the largest and most numerous ephemeral lakes in the Murray– Darling Basin. The lower Darling River and the Murray River flow through the traditional land of different Aboriginal nations and the catchment contains many significant spiritual and cultural sites, including Lake Mungo in the Willandra Lakes Region. Kinchega National Park near Menindee includes 62  km of Darling River frontage and is one of only two large conservation areas along the river. It protects substantial areas of River Red Gums, acacia and bluebush communities. Vegetation in the lower Darling consists largely of River Red Gum woodland in the riparian zone and immediate floodplain with extensive areas of Black Box woodland and Lignum. Chenopod shrublands, which include saltbush and bluebush, dominate the lakebeds and alluvial floodplains of the Great Darling Anabranch. The region is sparsely populated with a few small towns, such as Menindee, Pooncarie and Wentworth. The Lower Darling Catchment has 10 species of frogs and 85 species of reptiles. A study of nine Belah woodland sites using pit-falling and hand-collecting methods in this catchment revealed a richness of herpetofauna species. These included Sudell’s Frog (Neobtrachus sudellae), Broad-banded Sand-swimmer (Eremiascincus richardsonii) and Bynoe’s Gecko (Heteronotia binoei). 17

Lachlan Catchment

The headwaters of the Lachlan River are at elevations of 1400  m on the Breadalbane Plain between Yass and Goulburn in the Great Dividing Range in central New South Wales. The river flows north and then west through a varied landscape, with vegetation ranging from temperate forests, woodlands and grasslands in the east to semi-arid woodlands, mallee and scrublands in the 18

west. It is the fourth longest river in Australia, being 1339  km. It terminates at the Great Cumbung Swamp but during times of high flow, water will continue southwards through the swamp to reach the Murrumbidgee River. The eastern end of the catchment with temperate forests has an annual average rainfall of 800–1000 mm. The western end of the catchment is located on warm–hot semi-arid plains and receives an annual average rainfall of 300 mm. The wetlands and the river floodplains of this catchment are extensive and unique, providing a wide range of aquatic habitats such as pools, backwaters and billabongs. The lower Lachlan floodplain has nine nationally important wetlands, including Lake Brewster, the Booligal Wetlands and the Great Cumbung Swamp. This swamp features one of the largest stands of River Red Gums in New South Wales. Water extraction rates in the catchment are high, and combined with naturally high evaporation rates, flows into the wetlands have been very low over recent decades. The catchment is home to ~4% of the human population of the Murray–Darling Basin, and major towns include Boorowa, Cowra, Canowindra, Forbes and Hillston. Livestock grazing is the main industry along with irrigated crops.

INTRODUCTION

The Lachlan Catchment has 27 species of frogs and 67 species of reptiles. Lake Cowal is a prominent feature of this catchment and is the largest inland lake in New South Wales. The lake is ephemeral, being fed by the small Bland Creek and by the occasional flooding of the Lachlan River. The lake and surrounding areas provide important habitat for species such as the Giant Banjo Frog (Limnodynastes

interioris), Barking Frog (Limnodynastes fletcheri) and the Spotted Black Snake (Pseudechis guttatus), which reaches the southern limit of its distribution in this area.

Murrumbidgee Catchment

The Murrumbidgee Catchment is located in New South Wales and the Australian Capital Territory. Australia’s third longest river, the Murrumbidgee, begins its journey in the Australian Alps before flowing 1690  km to join the Murray River near Boundary Bend in northern western Victoria. The Murrumbidgee River’s largest tributary, the Tumut River, is part of the Snowy Mountains Hydro-electric Scheme. Almost one third of the Basin’s human population live in the Murrumbidgee Catchment and it is the largest area of fruit and vegetable production in Australia. Major towns include Cooma, Canberra, Yass, Tumut, Gundagai, Cootamundra, Wagga Wagga, Narrandera, Leeton, Griffith, Hay and Queanbeyan. Annual average rainfall in the catchment ranges from over 1600  mm in the cool temperate alpine regions at an elevation up to 1400 m, to around 350 mm on the semi-arid plains of western New South Wales. The Murrumbidgee River is

an important water source for many wetlands, including Fivebough and Tuckerbill swamps near Leeton and 16 wetlands listed as nationally significant. The Lowbidgee floodplain is the largest wetlands remaining in the Murrumbidgee Valley. Located between Maude and Balranald, the floodplain covers an area of over 2000  km2. It contains the second largest River Red Gum forest in Australia (along the river downstream of Redbank Weir) and significant Black Box, Lignum and reed-bed communities. These wetlands support a variety of wildlife. The MidMurrumbidgee wetland is a network of riverine lagoons and billabong formations that occur along the river between Narrandera and Carrathool. These wetlands rarely dry out completely and provide drought refuge for a wide range of species including many listed as Endangered or otherwise threatened. The Murrumbidgee Catchment has 28 species of frogs and 72 species of reptiles found through a variety of habitats from high mountain ranges with montane forest to woodlands, wetlands and semi-arid floodplains. The colourful Northern Corroboree Frog (Pseudophryne pengilleyi) occurs only in this catchment, being restricted to the Brindabella and Fiery Ranges of the Australian Capital Territory and New South Wales. The Yellow-spotted Frog (Litoria castanea) has a confused taxonomic history and was re-discovered in a stream near the ACT in 2010. Another interesting species from this catchment is the Wagga Wagga Blind Snake (Anilios batillus) known from only one specimen, presumed to have been collected at Wagga Wagga in the late 1800s. 20

Lower Murray Catchment

The Lower Murray Catchment is extensive and extends from near Wemen in northern Victoria to south-west of Broken Hill, New South Wales and south to Goolwa South Australia. The Murray River flows through a large semi-arid region that makes up ~9% of the area of the Basin. Much of it is dry mallee country, though the area contains many

significant wetlands, including the Riverland wetland, the Chowilla Floodplain, Lake Alexandrina, Lake Albert and the Coorong at the Murray mouth. Most of the area experiences hot summers and low annual rainfall. Much of the Lower Murray Catchment is sparsely populated, with pastoral grazing holdings to the north and large dryland cropping enterprises to the south. Towns include Mildura, Renmark, Morgan and Murray Bridge. The Riverland area from Renmark to Morgan, is highly developed with a diverse horticultural industry, as well as dryland agriculture. The Murray River makes a westerly course through the Mallee until Morgan where it turns south and flows for ~200 km through a limestone gorge to Mannum. Beyond this limestone gorge, the river enters the last stage of its journey towards the sea. Finally, it flows into Lake Alexandrina and out to the Southern Ocean through the Murray Mouth estuary. There are many areas along the river’s path with extensive floodplains. Groundwater is found in extensive alluvial systems throughout the lower Murray catchment and is highly connected with surface water. Water quality varies between aquifers, and many aquifers, particularly near the Murray River, are highly saline.

The Mallee region of north-western Victoria comprises almost one-fifth of the state, with important mallee habitat extending into nearby South Australia. It includes the Sunset Country, HattahKulkyne and Big Desert. These significant areas of mallee and heathland vegetation support only a few frog species such as the Painted Frog (Neobatrachus pictus), but are densely populated with reptiles. The Lower Murray Catchment has 11 species of frogs and 93 species of reptiles. Many lizards occur in this region including the Western Blue-tongued Lizard (Tiliqua occipitalis), Shingleback (Tiliqua rugosa aspera), Bull Skink (Liopholis multiscutata), Mallee Tree Dragon (Amphibolurus norrisi), Painted Dragon (Ctenophorus pictus), Sand Goanna (Varanus gouldii) and Eared Wormlizard (Aprasia aurita). Snake species include

Mid-Murray Catchment

The Mid-Murray Catchment includes areas on both sides of the Murray River, from Hume Dam in the east, upstream from Albury, to the confluence of the Murray and Darling rivers at Wentworth, in western New South Wales. This catchment covers only ~3% of the Basin area, but many of the major rivers such as the Kiewa, Ovens, Goulburn, Campaspe, Loddon and Murrumbidgee enter the Murray River in this region and account for over 50% of the inflow of the Basin. The Murray River is quite wide in this catchment and flows steadily through

predominantly riverine plain, though there are also extensive floodplains and wetlands. These include nationally and internationally significant sites such as the Barmah– Millewa Forest and the Gunbower– Koondrook–Perricoota Forest. This is a highly developed catchment with many large urban centres established on the banks of the Murray River. Major towns include Albury–Wodonga, Yarrawonga, Echuca–Moama and Deniliquin. There are significant dryland and irrigated agricultural industries located within the region. Tourism associated with the river environment and water activities are also economically important to the region. Average annual rainfall ranges from 700  mm in the east to ~500  mm in the western end of the catchment. Summers are hot and dry and rainfall is received mostly in winter and spring. Expansive River Red Gum forests are a feature of this region and periodic flooding supports large stands of these trees. Within the forests are complex networks of wetlands, some of which support locally and nationally significant wetland plants, such as Moira Grass, Tall Spike Rush and Common Nardoo. The Murray River and its surrounding wetlands provides important habitat for many frogs, turtles, snakes and lizards. The Mid-Murray Catchment has 18 species of frogs and 40 species of reptiles. A poorly known frog species, Sloane’s Froglet (Crinia sloanei) occurs in this catchment and may have contracted from much of its former range in recent years. Three species of freshwater turtles, Macquarie Turtle (Emydura macquarii),

Upper Murray Catchment

The Murray River begins its journey high in the Australian Alps, ~40  km south of Mount Kosciuszko at over 1000 m. Snow is present on these alpine meadows for several months each year and the average annual rainfall at the head of the catchment is ~1500  mm. The river originates from springs that form a small stream that flows westwards and then northwards through the Alpine and Kosciuszko national parks. This stream becomes larger as it is joined by many mountain creeks and rivers, the most significant being the Swampy Plain River. Much of the volume of this river is increased by the Geehi River, which carries water through the Snowy Mountains Hydro-electric Scheme, including water diverted from the Snowy River.

Other creeks and rivers that rise and merge in the mountains meet the Murray River as it flows through the foothills. The Koetong, Cudgewa, Corryong and Thowgla creeks are major Victorian tributaries of the upper River Murray and the Swampy Plain, Tooma rivers and the Tumbarumba Creek are the main tributaries in New South Wales. After the river descends the steep western slopes of the Great Dividing Range, it flows westwards across the riverine plains. Major towns of the catchment are Corryong, Khancoban and Tumbarumba. The western boundary of the Upper Murray Catchment is the Hume Dam, with the Murray forming the north arm of the reservoir. The Mitta Mitta River flows into the southern arm of the Hume Dam. Rainfall occurs across the catchment throughout the year but the highest falls are in winter and spring, with the annual average being ~700 mm. Surface water and groundwater systems in the catchment range from being highly connected, mainly in the mountains, to disconnected in other areas. Most upland streams receive flow from fractured granite and sedimentary rock aquifers and alluvial groundwater is associated with the floodplains of some streams and rivers. Much of the Upper Murray Catchment is undeveloped, with large areas of natural mountain environment and has 21 species of frogs and 42 species of reptiles. The iconic Southern Corroboree Frog (Pseudophryne corroboree), with striking black and bright-yellow stripes, only occurs in sphagnum bogs above 1200  m, within Mount Kosciuszko National Park. The Snowy Mountains Banjo Frog (Limnodynastes dumerilii fryi) is also 24

restricted to this catchment. Other frog species that occur here are the Alpine Tree Frog (Litoria verreauxii alpina) and Booroolong Frog (Litoria booroolongensis), both of which are Endangered. Reptile species include the Copper-tailed Skink (Ctenotus taeniolatus), Mountain Dragon (Rankinia diemensis), Alpine Copperhead (Austrelaps ramsayi) and Eastern Smalleyed Snake (Cryptophis nigrescens).

INTRODUCTION

Wimmera Catchment

The Wimmera Catchment is located in the south-west corner of the MDB and represents 3% of the whole Basin, providing 1.7% of its inflow. The main river is the Wimmera, which begins in the Pyrenees Ranges and flows across the northern foothills of the Grampians in western Victoria. The river ends at Lake Hindmarsh in the north of the catchment but in times of peak flow its waters reach Lake Albacutya. East of the Wimmera are two smaller, northwardflowing rivers, the Avon and the Richardson, which rise in the Pyrenees Ranges. The Avon flows into the Richardson, which ends at Lake Buloke. Neither river connects to the Wimmera. This catchment is home to ~2% of the human population of the Basin and the larger towns include Stawell, Horsham, Dimboola, Warracknabeal, Ouyen and St Arnaud. The main industry is dryland agriculture and the demand for water exceeds supply, with water being transferred from other regions for stock and domestic use. Average annual rainfall varies across the catchment from 1000  mm in the south to 300  mm in the north, with winter typically being the wettest season.

The Wimmera River is the largest landlocked river in Victoria with its headwaters near Mount Cole, south of the Pyrenees Ranges, in central Victoria and flows for over 150 km to Lake Hindmarsh, Victoria’s largest freshwater lake. In times of peak flow, the lake will overflow and the Wimmera’s waters will reach Lake Albacutya and a series of smaller lakes in the Victorian Mallee. The catchment contains a range of environmental features and significant wetland ecosystems including Pink Lake, Natimuk Lake, Oliver’s Lake and White Lake. Areas of herpetological interest include the Grampians National Park, known for its sandstone mountains, Mount Arapiles, a rock formation that rises ~140 m above the Wimmera plains and the 132 647  ha Little Desert National Park, which is situated near Dimboola that extends from the Wimmera River in the east to the South Australian border in the west. The Wimmera Catchment has 13 frog species and 57 reptile species. Some of the frog species are capable of surviving in drier habitats by burrowing. These include Sudell’s Frog (Neobtrachus sudellae), Painted Frog (Neobtrachus pictus), South-eastern Banjo Frog (Limnodynastes dumerilii dumerilii) and Variegated Banjo Frog (Limnodynastes dumerilii variegatus). There are also important wetland areas in this catchment with good populations of the Endangered Southern Bell Frog (Litoria raniformis). Notable reptile species include the Tessellated Gecko (Diplodactylus tessellatus), Lined Worm-lizard (Aprasia striolata), Heath Monitor (Varanus 25

Loddon-Avoca Catchment

Like many rivers of the southern Murray– Darling Basin, the Loddon and Avoca rivers rise at elevations up to 600 m within the Great Dividing Range of south-central Victoria. From these hilly woodlands the rivers descend northwards through 26

undulating foothills and onto the warmer plains of northern Victoria. The Loddon River is the second longest river in Victoria. It has many tributaries and is important for wetland systems on the lower Loddon River floodplain, such as Boort District Wetlands and the Kerang Lakes. Beyond the wetlands, the Loddon joins the Little Murray River (an offshoot of the main Murray River) north of Kerang and eventually the Murray River at Swan Hill. Within this catchment the Bendigo and Bet Bet creeks also flow from the ranges to wetlands on the northern floodplains. The Avoca River runs west of the Loddon River, rising south of the Pyrenees Ranges then flowing 270   km north to terminate at Lake Bael Bael, between Kerang and Swan Hill. In times of high flow, the waters from the river will reach the Kerang Wetlands and the Murray River.

INTRODUCTION

The Avoca River splits into several channels, its pattern of flow being the most variable of all Victorian rivers in the Basin. In the eastern parts of the region there is an average annual rainfall of up to 1200  mm, but on the wide riverine plains in the north, which are much warmer and drier than the southern regions, the annual rainfall is ~350  mm. Main towns include Bendigo, Maryborough, Castlemaine, Kerang, Avoca, St Arnaud, Charlton and Sea Lake. Broadacre cropping is the major agricultural activity in dryland parts, producing cereals, pulses and oilseeds. Wheat is the most prevalent crop, followed by barley. This catchment experiences hot summers and cool winters. The Boort District Wetlands at the northern end of the Loddon provide a range of important habitats in a heavily modified catchment, including the deep water marsh, Woolshed Swamp. The wetlands and billabongs of the Gunbower Forest are recognised as extremely important habitat and nesting sites for freshwater turtles. The Loddon-Avoca Catchment has 14 species of frogs and 55 species of reptiles. Commonly encountered frogs include Peron’s Tree Frog (Litoria peronii) and Fletcher’s Frog (Limnodynastes fletcheri). Reptile species include Macquarie Turtle (Emydura macquarii), Snake-necked Turtle (Chelodina longicollis), Broad-shelled Longnecked Turtle (Chelodina expansa), Eastern Hooded Scaly-foot (Pygopus schraderi), Eastern Bearded Dragon (Pogona barbata), Lace Monitor (Varanus varius), Inland Carpet Python (Morelia spilota metcalfei), Mainland Tiger Snake (Notechis scutatus) and Curl Snake (Suta suta).

Campaspe Catchment

The Campaspe River rises in wooded, hilly terrain at elevations up to 600  m south of Woodend in the Central Highlands of Victoria. It descends through undulating foothills that form part of the Great Dividing Range and flows onto the wide, flat riverine plains of northern Victoria before it joins the Murray River at Echuca. 27

The cooler headwaters of the region have an average annual rainfall of up to 1000  mm, while the riverine plains are much warmer and drier than the southern regions, with annual rainfall being around 400 mm. The waters of the Campaspe River are highly regulated and natural flows have been disrupted. Environmental flows are important to maintain several threatened vegetation communities, aquatic life and habitat for many terrestrial species. The Campaspe has many tributaries, the main one being the Coliban River, which joins the Campaspe at Lake Eppalock, the major water storage in the catchment. The Campaspe Catchment is home to ~2% of the human population of the Basin. The largest source of income is primarily derived from dryland agriculture across much of the catchment, but on the lower plains of the Campaspe River dairying is the main industry. Water from the catchment supplies main towns such as Kyneton, Rochester and Echuca. Parts of the region are heavily forested, with some areas supporting commercial forestry and agriculture. Groundwater in the catchment exists in alluvial aquifers in the northern catchment, and fractured rock aquifers in 28

the central and southern catchment. Shallow aquifers in the region can be quite saline but deep aquifers contain good quality water. This is one of the smaller catchments and experiences hot summers and cooler winters. The Campaspe Catchment has 14 frog species and 51 reptile species. Common frogs in this catchment include the Brown Tree Frog (Litoria ewingii), Striped Marsh Frog (Limnodynastes peronii) and Spotted Marsh Frog (Limnodynastes tasmaniensis). Reptile species include Common Thick-tailed Gecko (Underwoodisaurus milii), Olive legless Lizard (Delma inornata), Cun n i ng ham’s Sk in k ( Eg e r nia cunninghami) and Eastern Brown Snake (Pseudonaja textilis).

Goulburn-Broken Catchment

The Goulburn–Broken Catchment has many creeks and rivers that flow into the two main rivers in the mountains and highlands of Northern Victoria. The Goulburn and Broken rivers are fed by high annual rainfall and melting snow, contributing 11% of the Basin’s water. The Goulburn River rises south of Lake Eildon

more than 1800  m above sea level in the Great Dividing Range and flows through montane forests in deep valleys at an elevation of ~300  m. The Broken River rises in forested country in the Wellington– Tolmie highlands south of Benalla, with an elevation up to 1000  m. The headwaters of the Goulburn and Broken rivers are the southern-most of all rivers of the Basin. They are clear, cold and fast-flowing with gravel and rubble beds. The Goulburn River is one of the largest tributaries of the Murray River and since the 1880s its waters have been diverted for irrigation and urban use. It is one of the most regulated rivers of the Murray– Darling Basin. The Broken River emerges onto the riverine plain at Benalla and then splits. The river continues westwards and the Broken Creek flows northwards and then westwards past Nathalia, joining the Murray River upstream of Barmah. The Broken River meets the Goulburn River at Shepparton and the Goulburn continues north-west for about another 100  km to where it joins the Murray River, upstream of Echuca. The rivers are fed by high annual rainfall, on average up to 1600  mm in the mountains, reducing significantly to 400–500  mm on the northern plains. This catchment experiences hot summers and very cold winters. The catchment is home to ~7% of the human population of the Basin and the income of the region is derived from wholesale and retail trade, food processing, agriculture and community services. Dairy and fruit production are the key industries that use irrigation water in the region. The major towns are Shepparton, Kyabram, Benalla, Seymour and Mansfield. 29

The Goulburn-Broken Catchment has 19 species of frogs and 51 species of reptiles. Some common frogs of this catchment include the Stony Creek Frog (Litoria lesueuri), Victorian Tree Frog (Litoria paraewingi) and Eastern Sign-bearing Froglet (Crinia parinsignifera). Reptile species include Eastern Stone Gecko (Diplodactylus vittatus), Marbled Gecko (Christinus marmoratus), McCoy’s Skink (Anepischetosia maccoyi), Southern Rainbow Skink (Carlia tetradactyla), Black Rock Skink (Egernia saxatilis intermedia), Jacky Lizard (Amphibolurus muricatus), Lowlands Copperhead (Austrelaps superbus) and Little Whip Snake (Parasuta flagellum).

Ovens Catchment

The Ovens River rises at an elevation up to 1800  m in the Victorian Alps near Mount Feathertop and Mount Hotham, from significant freshwater grasslands and marshes in the Alpine and Mount Buffalo national parks. It then flows northwestwards towards Bright, fed by numerous creeks and is joined by the north-flowing Buffalo River at Myrtleford. The King River, the second largest river in the catchment, joins the Ovens River on the floodplain at Wangaratta. After Wangaratta, the river flows northwards across the plain and is joined by the Reedy and Fifteen Mile creeks. The Ovens River then flows through wetlands and River Red Gum forests into the Murray River east of Lake Mulwala.

INTRODUCTION

Annual average rainfall in the catchment ranges from more than 1400  mm in the mountains of the Great Dividing Range in the south to 500–600  mm on the plains in the north near the Murray River. About 65% of the annual rainfall is during the cold winter where snow covers the high ground. Summer rainfall is less frequent. The Ovens River Catchment is home to ~2.3% of the human population of the Basin. Beef and sheep grazing are the major sources of income, though there is also viticulture, horticulture and orchards. Tourism is important to the region, with a focus on food and wine, fishing and snow sports. Major towns include Bright, Beechworth, Myrtleford and Wangaratta. The region contains numerous important river sites, including several nationally significant wetlands, such as the lower reaches of the Ovens River, extending from the confluence of the Ovens and King rivers to Lake Mulwala. This catchment supports a wide range of habitats, from the alpine grassland and heath in the Australian Alps to the Victorian riverine plains. The wetlands are close to the Murray River and this corridor features an extensive network of billabongs, anabranches and islands. It provides important habitat for various species of frogs and reptiles. The Ovens Catchment has 15 species of frogs and 47 species of reptiles. Frog species include the Whistling Tree Frog (Litoria verreauxii verreauxii), Common Signbearing Froglet (Crinia signifera) and Bibron’s Toadlet (Pseudophryne bibronii). Reptile species include the Snake-necked Turtle (Chelodina longicollis), Pink-tailed Worm-lizard (Aprasia parapulchella),

Red-throated Skink (Acritoscincus platynotum), Ragged Snake-eyed Skink (Cryptoblepharus pannosus), Lace Monitor (Varanus varius), Blackish Blind Snake (Anilios nigrescens), Red-bellied Black Snake (Pseudechis porphyriacus) and Bandy Bandy (Vermicella annulata).

Kiewa Catchment

Kiewa Catchment is the smallest in the Murray–Darling Basin, though it makes a significant contribution to flows in the Murray River. The landscape of the catchment ranges from the high plains of the Great Dividing Range, at around 1600  m, to the northern floodplains near Albury–Wodonga with an elevation of around 160 m. The east and west branches of the Kiewa River rise in the alpine environment of the Great Dividing Range, south-east of Mount Bogong. The western branch rises near Mount Hotham, then flows northwards, mostly unregulated, through a steep forested valley. The east branch begins as a series of small streams near Falls Creek and flows northwards, delivering water to a series of pondages, tunnels and aqueducts for the largest hydro-electric scheme in Victoria. The east branch of the Kiewa River is joined by the Bogong and Mountain creeks before merging with the west branch of the Kiewa north of Mount Beauty. The Kiewa River then flows northwards through a widening valley with significant remnant vegetation and some of the most productive farming land in north-east

Victoria. The lower reaches of the river divert into floodplain wetlands before merging with the Murray River between Albury–Wodonga and Lake Hume. Most of the catchment receives more than 700  mm average annual rainfall, with the Bogong High Plains experiencing almost 2500 mm, including snow in winter. The upper reaches of the Kiewa River feature alpine wetlands of national significance. Remnant patches of significant riparian vegetation occur along most of the Kiewa River and is in good to excellent condition in the higher reaches, but steadily declines downstream. There are no major urban centres in the Kiewa Valley. Small towns include Tangambalanga, Kiewa, Yackandandah, Mount Beauty and Falls Creek. About 50% of the water extracted from the Kiewa River is for urban use and industry. The other half is for irrigated agriculture, predominantly dairying. Tourism is important to the region, with a focus on fishing and snow sports. The Kiewa Catchment has 16 species of frogs and 42 species of reptiles. These include the Southern Green Stream Frog (Litoria nudidigitus), Victorian Tree Frog (Litoria paraewingi), Spotted Tree Frog (Litoria spenceri), Alpine Tree Frog (Litoria verreauxii alpina), Victorian Smooth Frog (Geocrinia victoriana), Dendy’s Toadlet (Pseudophryne dendyi), Olive Delma (Delma inornata), Alpine She-oak Skink (Cyclodomorphus praealtus), Alpine Water Skink (Eulamprus kosciuskoi), Guthega Skink (Liopholis guthega), Highlands Copperhead (Austrelaps ramsayi) and White-lipped Snake (Drysdalia coronoides).

Mitta Mitta Catchment

The Mitta Mitta River rises on the high plains beneath Mount Bogong, and the upper reaches and tributaries of the Mitta Mitta River flow through heavily forested areas. The main channel of the Mitta Mitta forms at the confluence of Cobungra River and the Big River and then flows northwards through forest to the Dartmouth Dam. This dam is the largest storage in the MDB and has the capacity to hold up to 40% of the water for the Murray River system. After Dartmouth Dam, the Mitta Mitta flows north-westwards through a wide valley to the south arm of the Hume Dam. The Mitta Mitta Catchment comprises less than 1% of the area of the MDB but it provides almost 10% of inflow to the Murray River system. The Mitta Mitta River is a declared heritage river area in its mountain reaches, from Glen Valley to Lake Dartmouth. The dam has strongly affected the hydrology of the lower river but good floodplain, billabong and wetland habitats exist downstream of Tallandoon on the lower reaches of the river. There are farming communities in the Mitta Mitta Catchment, though ~70% of 34

the region is steep, forested mountains. The dairy industry is a major source of income and employment in the region and, to a lesser extent, timber and beef production. Tourism is also important with a focus on fishing, camping and fourwheel driving. Small towns in this catchment include Dartmouth, Eskdale and Mitta Mitta. Most of the catchment has an average rainfall over 700 mm but increases with elevation to 2400  mm at Mount Bogong. Elevation across the catchment ranges from 150  m at Hume Dam to 2200  m at the alpine peaks in the south. Significant remnant vegetation can be found along most of the river system, providing important riverine habitat, which includes healthy stands of River Red Gum. Good riparian vegetation in the upper reaches of the Mitta Mitta provides

habitats for wildlife, but with restricted diversity due to water regulation. The Mitta Mitta Catchment has 18 species of frogs and 40 species of reptiles. These include the Green and Golden Bell Frog (Litoria aurea), Brown Tree Frog (Litoria ewingii), Stony Creek Frog (Litoria lesueuri), Southern Green Stream Frog (Litoria nudidigitus), Spotted Tree Frog (Litoria spenceri), Alpine Tree Frog (Litoria verreauxii alpina), Victorian Smooth Frog (Geocrinia victoriana), Dendy’s Toadlet (Pseudophryne dendyi), Smooth Toadlet (Uperoleia laevigata), Eastern Striped Ctenotus (Ctenotus robustus), Southern Water Skink (Eulamprus tympanum), Mountain Skink (Liopholis montana), White’s Skink (Liopholis whitii), Alpine Bog

Australia has a rich and varied herpetofauna, with 246 species of frogs and 1011 species of reptiles so far described. The continent is a large, green-edged desert, with the greatest number of frog species found along the moist east coast, though high numbers of reptiles occur throughout the arid zones. There are 66 species of frogs and 244 reptiles recorded from within the boundaries of the Murray–Darling Basin. This includes representatives from four families of frogs and 12 families of reptiles. Many of these frogs and reptiles are arid or semi-arid adapted and true inhabitants of typical inland environments containing sand dunes, floodplains, ephemeral claypans, shrublands, woodlands and heathlands. Areas of 35

F R O G S A N D R E P T I L E S O F T H E M U R R AY – D A R L I N G B A S I N

spinifex grasslands provide a great number of reptile species with refuge from the heat and some security from predators. Certain species of lizards occur only in association with this vegetation type. The species that are found in these environments experience high summer temperatures, cooler winters and low annual rainfall. They have developed strategies for dealing with these extremes, most notably the ability to burrow. Some of these species are observed above ground only at night during the summer months, often after rainstorms. On the western slopes of the Great Dividing Range near the headwaters of many inland flowing rivers, species of frogs and reptiles can be found that are associated more with the moist coast and ranges, though their distribution extends slightly into the Murray–Darling Basin. The northeastern region experiences high summer rainfall and mild winters and some of the species that occur there include rainforest inhabitants.

36

In the temperate southern Murray– Darling Basin, frogs and reptiles are distributed through a variety of habitats including volcanic plains, rocky outcrops, wetlands, woodlands, forests and alpine grasslands. Some unique species occur in high elevation areas and experience a long period of inactivity during wet, cold winters.

Conservation status Some populations of frogs and reptiles have undergone serious declines throughout Australia and all species are protected. There are many species not listed as being threatened but may face a serious decline in the near future. Species listed at federal and/ or state levels as being of conservation concern (Critically Endangered, Endangered, Threatened, Near Threatened, Vulnerable, etc.) are indicated in each species account. There are global, national and state systems that recognise the conservation status of a species and status categorisation for a single species may differ between systems.

Frogs

Two-thirds of the Australian continent is dry to arid, so it is not surprising that native frog species represent only 3.58% of the world’s frog fauna. Australia has five families of frogs and one species of introduced toad. Frogs mostly occur in wetland systems, and water for creeks, rivers and wetlands is crucial in maintaining viable frog populations. Larger rural towns, widespread agriculture and mining in the MDB all place demands on available water in a landscape significantly altered by river regulation with managed flows. Traditional threatening processes such as habitat modification and pollution of waterways have contributed to the decline of frogs but climate change, disease and feral species also place pressure on frog populations. Thirty per cent of Australia’s frogs are officially listed as Threatened and that

proportion continues to climb with each new assessment of frog conservation status. Drivers of profound declines in frog populations were not well understood for  many decades, until the identification of  a frog fungal disease in the 1990s. The  disease chytridiomycosis is caused by  the amphibian chytrid fungus (Batrachochytrium dendrobatidis). Frogs have permeable skin and are particularly nostril

vulnerable to pollutants and pathogens. Chytrid fungus infects the keratinised epidermal layers of the skin and, for many species, causes the terminal disease chytridiomycosis. It can also infect the keratinised mouthparts of tadpoles, but

does not cause disease until after metamorphosis, when infection spreads to the developing skin. The fungus is a microscopic waterborne pathogen that has severely affected susceptible frogs, even in relatively pristine habitats. This invasive disease likely originated in Africa or Asia and has since been recorded in various habitats across Australia, particularly in areas of high elevation with cooler temperatures. Despite the best efforts to manage it, this single pathogen has caused the massive decline and extinction of hundreds of species around the globe. Chytrid fungus is a significant threat to frog species in the cooler, moist uplands of the MDB but it apparently does not pose as great a risk, in the drier, warmer, inland areas. Several Threatened frog species that occur in the MDB have suffered serious declines due to chytridiomycosis but declines also occur due to, or are made worse by, other threatening processes. Feral ungulates, including horses, pigs and deer have become well established. Crucial frog habitat is damaged by these large animals, churning up bogs and ponds creating deep gutters, which allows water to flow rather than drain slowly through soaks. Nutrients in manure also enter the system causing further pollution. One subspecies affected by the action of these animals is the Alpine Tree Frog (Litoria verreauxii alpina), which breeds during spring in seasonal and perennial ponds in subalpine regions of south-eastern Australia. Efforts are being made to fence off some remaining habitat for this frog to try and prevent this type of damage occurring. Habitat modification and extreme 39

drought conditions have impacted species such as the Booroolong Frog (Litoria booroolongensis), which has declined from more than half of its historic known range. However, this species persists along many streams, including those flowing through agricultural landscapes. Widespread loss and degradation of habitats is common in the tablelands, slopes and lowland regions and has contributed to the decline of the Green and Golden Bell Frog (Litoria aurea), Southern Bell Frog (Litoria raniformis) and Yellow-spotted Frog (Litoria castanea). However, the Southern Bell Frog has no doubt benefited from the development of rice farms in the southwestern Murray–Darling Basin, due to the large amounts of water required to cultivate that crop. The Spotted Tree Frog (Litoria spenceri) inhabits naturally vegetated, swift-flowing upland streams in mountainous country of the Great Dividing Range, between the Central Highlands of Victoria and Mount Kosciusko, in southern NSW. Historically it occurred along 23 streams, but extensive surveys have shown that this species has undergone major declines due to chytridiomycosis and predation from introduced trout. Sloane’s Froglet (Crinia sloanei) was listed as Vulnerable in NSW after a noticeable decrease in the rate of observations over the past few decades. The Southern Corroboree Frog (Pseudophryne corroboree) historically occurred across a 500  km2 area of the Snowy Mountains

40

Region of Kosciusko National Park and was recorded in extremely high abundance during the 1960s and 1970s. It has undergone a rapid and ongoing decline that commenced sometime during the early to mid1980s. The estimated number of frogs remaining in the wild in 2017 was fewer than 50, with the majority of these individuals recorded at reintroduction sites. Three geographically and genetically distinct populations of the Northern Corroboree Frog (Pseudophryne pengillyei) have been identified, each of which is considered a high priority for management. This species underwent a rapid decline associated with the emergence of chytrid fungus. Feral horses continue to degrade the habitat of this species. Government organisations, conservation groups, zoos and wildlife parks have recognised a need for collaboration and a diversity of approaches both in the wild and in captivity. Zoos Victoria, Taronga Zoo and the Amphibian Research Centre, in conjunction with the Arthur Rylah Institute and Office of Environment and Heritage, have all contributed to monitoring wild populations and developing captive breeding programs, with a view to reintroduction, for threatened frog species. Captive management and development of breeding programs is an important part of frog conservation, along with reducing threatening processes in the wild and the preservation of existing habitat. Four of the six families of Australian

Foam-nesting ground frogs (Family Limnodynastidae) A family consisting of small to large ground-dwelling frogs that occur in a variety of habitats throughout Australia. They lack discs on their fingers or toes and some species are adapted to burrowing and have noticeably large shovel shaped metatarsal tubercles. Most species have prominent eyes and may have a horizontal or vertical pupil. With the exception of the genus, Neobatrachus, they all produce eggs in a floating, foamy eggs mass and are often laid in temporarily inundated depressions or ponds. They perform inguinal amplexus and females often have flanged fingers to help create the frothy nest.

Tusked Frog (Genus Adelotus) The sole member of this genus, Adelotus brevis, is a medium-sized frog with a broad head. Males have a large pair of ‘tusks’ at the front of the lower jaw, which are only visible if the jaw is opened. The purpose of these tusks is not well understood but the males which are larger than the females 42

may use them in encounters over territory and sexual selection. The Tusked Frog occurs in the northeastern area of the MDB, being more associated with the coast and ranges. Tusked Frog Adelotus brevis

legs. Groin, thighs and lower legs with bright red or orange patches. Fingers and toes with trace of webbing, with females having broad flanges on first and second fingers. Habitat: Found around permanent water in wet and dry sclerophyll forest, and also farmland in the north-east of the MDB. Notes: Males call during spring and summer from inside crayfish burrows or nests hidden beneath vegetation and leaf litter at the edges of ponds and stream pools. The call is a slowly repeated, moderately pitched ‘g-lunk’. Females deposit unpigmented eggs in foam clumps and tadpoles are a deep dark brown. Metamorphosed frogs have been recorded from December to February.

Limnodynastes is a genus containing 15 species that occur in different regions of Australia. It is well represented in the MDB, with four species of stout marsh frogs and five species of the well-known, globular shaped, banjo frogs. These frogs occupy a wide variety of habitats with marsh frogs generally found in association with still, permanent water and banjo frogs adapted for burrowing into the soil. Banjo frogs are readily identified by a prominent, large tibial gland. Members of the genus Limnodynastes may be confused with trilling frogs, genus Neobatrachus, but those species have a vertical pupil, or with Platyplectrum ornatum but that species usually has a distinctive hourglass shape on the dorsum.

unwebbed, toes about half webbed. Large shovel-shaped metatarsal tubercle. Habitat: Associated with dry, sandy regions in semi-arid woodlands and grasslands in the interior of the MDB. Notes: A very large burrowing frog observed in temporary pools after rain. Males call from within overhanging vegetation or burrows beside ponds, flooded ditches and channels during spring. The call is a deep, hollow ‘bonk’. Eggs are laid in floating foamy clumps among vegetation or in burrows. Tadpoles are grey-brown to olive with small gold markings and metamorphosed frogs probably appear over summer. Identification: Limnodynastes interioris can be identified by its large, distinctly orange tibial gland and half webbed toes. Conservation status: Not listed.

Noticeably long first finger. Adult males develop noticeably thicker more muscular arms, especially in breeding season. Habitat: Widespread in the MDB through flooded grasslands, wetlands, swamps and farm dams. Notes: A terrestrial frog that calls from within vegetation beside ponds or floating during spring, summer and autumn. The call is a bark-like ‘whuk’ repeated at irregular intervals. Eggs are laid in floating foamy clumps among vegetation. Tadpoles are deep dark brown with scattered darker spots. Metamorphosed frogs have been recorded in March, April, May and November. Identification: Limnodynastes fletcheri sometimes has rose pink colouring above the eyes and an irregular pattern on the dorsum without a vertebral stripe. Though slightly larger in size it is similar to Limnodynastes tasmaniensis from which it may be distinguished with absolute certainty only by the different call, measuring the fingers, genetic analysis, or if encountering an adult male Limnodynastes fletcheri with strongly developed muscular arms.

Trilling frogs (Genus Neobatrachus) This genus contains a group of mediumsized burrowing frogs that are distributed almost entirely across the southern half of the Australian mainland. In the MDB there are two similar species that are easily recognised by their large and bulbous eyes containing a vertical pupil. They are the only members of the family Limnodynastidae that do not produce foamy spawns. Eggs are laid singly or in broad floating masses that sink to the bottom. These are rotund frogs with short, stocky limbs, well adapted to burrowing underground for long periods. They are usually observed above ground only after rain periods breeding in temporary pools of water. Painted Frog Neobatrachus pictus

TL: Males 56–63 mm; females 48–56 mm Description: Body medium-sized and globular with short, broad head with broadly rounded snout. Dorsum with numerous small warts and pale grey, yellow 52

or brown with irregular darker brown or olive-green patches. Usually, thin cream or pale yellow vertebral stripe present. Tympanum indistinct. Eyes with vertical pupil and silver-grey iris. Ventral surface smooth and white. Fingers unwebbed and toes strongly webbed. Large, black, shovelshaped inner metatarsal tubercle. Upper surface of foot pigmented. Habitat: Mostly found in mallee woodlands, grasslands and arid areas of the southwestern MDB. Notes: A burrowing frog that can be heard calling after heavy rainfall from late summer to spring afloat in dams and temporary ponds. The call is a long, rapid low-pitched trill. Eggs are laid in a floating clump, which later sinks. Tadpoles are grey, golden or darker golden brown with scattered dark patches. Metamorphosed frogs have been recorded from September to November. Identification: Neobatrachus pictus is very similar to Neobatrachus sudellae from which it can be distinguished by lack of very loose skin from the side of the body near the groin to the knee. Conservation status: Endangered (NSW). MDB catchments: Lower Murray, Wimmera.

Dorsum with numerous small warts and quite variable in colour from grey-brown, yellow-brown to reddish brown with darker brown or olive patches and marbling. Usually, thin cream vertebral stripe present. Tympanum indistinct. Eyes with vertical pupil and silver-grey iris. Ventral surface smooth and white. Skin between side of body around groin to knee noticeably loose. Tympanum indistinct. Eyes with vertical pupil and

silver-grey iris. Ventral surface smooth and white. Fingers unwebbed and toes fully webbed. Large, black, compressed shovelshaped inner metatarsal tubercle. Upper surface of the foot is white. Habitat: Widespread in the MDB through rocky plains, woodlands and arid grasslands. Notes: A burrowing frog usually observed after rainfall. Males call while floating in temporary waterfilled depressions, ponds and dams during spring and summer. The call is a musical trill. Eggs are laid in a floating clump, which later sink, or in strings attached to vegetation just beneath the surface. Tadpoles are dark to lighter grey-brown, grey or silvery cream. Metamorphosed frogs have been recorded from September to December. Identification: Neobatrachus sudellae can be distinguished from N. pictus by the skin between the side of the body around the groin to the knee being noticeably loose.

Burrowing frogs (Genus Notaden) The genus Notaden is made up of four medium-sized, extremely rotund burrowing frogs that mostly inhabit the drier inland areas of Australia. A single species occurs in the MDB. They have a short, broad head with a bluntly rounded snout and large eyes. The dorsal surface is 53

F R O G S A N D R E P T I L E S O F T H E M U R R AY – D A R L I N G B A S I N

extremely warty and if disturbed they exude a thick, white toxin that becomes highly adhesive as it dries. Their egg masses are less foamy than those of other limnodynastid frogs. Notaden bennettii could be confused with members of the genus Neobatrachus but those species have a vertical pupil. Crucifix Frog Notaden bennettii TL: Males 42–63 mm; females 46–68 mm Description: Body medium-sized and globular with short head and bluntly rounded snout. Dorsum yellow, olive or green with numerous round, black warts and spots with smaller red dots that form distinct cruciform pattern. Tympanum indistinct. Eyes with horizontal pupil and golden iris. Throat brown with dark spots

in calling males. Ventral surface smooth and white. Fingers unwebbed and toes about one-quarter webbed. Pale coloured, shovel-shaped inner metatarsal tubercle. Habitat: Associated with drier, open woodlands, grasslands and claypans on sandy soils in the central and northern MDB. Notes: This colourful burrowing frog is usually observed above ground after very heavy rainfall. Males call from late winter to autumn around temporary pools. The call is an owl-like ‘whoop…whoop…whoop’. Eggs are laid in a clump that floats on the surface. Tadpoles are dark copper-brown, gaining the distinctive cruciform before metamorphosis. Metamorphosed frogs have been recorded from December to March. Identification: Notaden bennettii is a distinctive frog with a black and red spotted cruciform pattern. Conservation status: Not listed.

A group of medium-sized, robust frogs that only occur in forested mountainous areas of south-eastern Australia. Six species are recognised but only one is recorded from within the MDB. The head is short and broad with a rounded or slightly pointed snout and the pupil is horizontal. The fingers and toes are entirely free of webbing but the females possess a very large flange on the inner two fingers used for creating a frothy egg mass. Hidden nests are created in moist soaks and bogs along small streams in which the females lay a small number of large,

unpigmented eggs. Partial development occurs within the egg, and partially as tadpoles, in the small, moist nest. Mountain Frog Philoria kundagungan TL: Males 22–28 mm; females 24–30 mm Description: Body medium-sized and stout. Dorsum smooth and bright red, yellow, orange, purple-red, reddish brown to black. Usually, black V-shaped marking above each groin. Inconspicuous parotoid glands. Head broad with rounded snout. Tympanum indistinct and eyes with brown iris. Ventral surface smooth, uniform bright yellow with red patches on throat. Fingers and toes unwebbed. Females with broad flanges on first and second finger.

Habitat: Found in montane subtropical rainforest in a small range in the Mistake Mountains of the north-eastern MDB. Notes: Males call from August to midFebruary from nest sites under rocks or leaf litter in soaked holes and the call is a slow, guttural low-pitched ‘ork’. Eggs are deposited in a small foamy mass. Tadpoles are cream but become lightly pigmented, and metamorphosed frogs have been recorded in January. Identification: Philoria kundagungan is the only species of Philoria in the MDB and this colourful frog with a bright red, orange or purple-red dorsum and yellow patches is unlikely to be confused with any other frog. Conservation status: Endangered (NSW). MDB catchments: Condamine-Balonne.

Platyplectrum comprises two rotund and squat, medium-sized frogs that occur throughout most of Australia, with one species occurring close to the MDB in south-western Queensland and the other widespread in the MDB. They are adept burrowers and can be found in many different habitats in sandy soils. Sometimes a distinctive hourglassshaped pattern is present on the back of the dorsum from behind the eyes and they display a great number of colour forms even within single populations. The squat, rotund body shape and size can loosely resemble some other burrowing frogs such as Neobatrachus species (but those have vertical pupils) and the globular banjo frogs Limnodynastes species (which have prominent tibial glands). 55

granular or smooth with numerous warts and ridges and highly variable in colour and pattern. Various forms include, pale sandy yellow, light to dark brown, olive green or red-brown with irregular variegated patterns or darker blotches and patches to uniform rust-red, with or without broad pale stripe from snout to vent. Most specimens with pale hourglass-shaped patch down back, starting behind the eyes. Hindlimbs barred with broad or narrow dark bands. Tympanum indistinct. Eyes with horizontal pupil and golden iris. Ventral surface smooth and white. Fingers unwebbed and toes one-quarter webbed. Breeding females with one or more inner fingers flanged. Habitat: Found in the north-eastern and north central areas of the MDB throughout a variety of habitats from forest to arid, sandy scrublands. Notes: A burrowing frog commonly observed moving around at night. Males call from spring to autumn while floating in water. The call is a reverberating ‘unk’ repeated frequently. Eggs are deposited in floating clumps that form small domes. Tadpoles are brown or dusky grey with fine gold pigment. Metamorphosed frogs have been recorded every month from December to early May. Identification: Platyplectrum ornatum is most easily identified by the squat, rotund body shape and size. It is similar to Neobatrachus species, but those have vertical pupils, and the globular banjo frogs Limnodynastes species, which have prominent tibial glands. Conservation status: Not listed.

Ground frogs (Family Myobatrachidae) These frogs were once part of the global family of southern frogs but now the Australian, non-foam nesting, ground frog species belong to the family Myobatrachidae. This is a small to medium-sized group of diverse, terrestrial frogs with small or no discs on fingers and toes. They range from burrowing species to entirely aquatic frogs. Most have no webbing between the toes and amplexus is inguinal. Different reproductive strategies are employed by a variety of species and, although most lay eggs directly in water, some have a terrestrial direct development, which is completed within the egg. They have a horizontal pupil and usually an indistinct tympanum.

Desert Froglet Crinia deserticola

Froglets (Genus Crinia) The genus Crinia contains a group of small, stout terrestrial frogs distributed widely on the Australian mainland and in Tasmania, but absent from arid central regions. Four species occur in the MDB. They are mostly drab with long, unwebbed fingers and toes. All species have a horizontal pupil and a granular ventral surface. They occur in conjunction with still or slow moving water and can be very difficult to identify. Their advertisement calls are sometimes the only definite way to differentiate between species. Crinia species are similar to Geocrinia species but can be distinguished by the  granular ventral surface (in Geocrinia  species the ventral surface is smooth).

Geocrinia is a genus of small terrestrial frogs that shelter beneath vegetation and rocks around wetlands usually within forested areas. They occur in the cooler south-eastern and south-western parts of Australia, including Tasmania. Two species occur in the southern areas of the MDB.

FROGS

Eggs are laid on land, where rainfall either triggers the hatching process and washes the tadpoles into a water body to develop or in some species the tadpole develops entirely on land where the eggs are laid. All species have a horizontal pupil and a smooth ventral surface. Geocrinia is distinguished from the very similar genus, Crinia by the smooth ventral surface (in Crinia species the ventral surface is granular). Southern Smooth Frog Geocrinia laevis TL: Males 23–27 mm; females 22–35 mm Description: Body small and stout with short wide head and rounded snout. Dorsum grey to reddish brown or yellowish

brown with darker bar between eyes and dark markings on upper lips. Skin smooth or with numerous small tubercles. Iris golden above and silver-grey below. Tympanum indistinct. Usually a darker line from the nostril through the eye, broadening to tympanum. Ventral surface smooth and white with some darker patches becoming marbled on groin and legs. Pink flush usually present in groin and armpit. Males with yellow throat. Fingers and toes unwebbed. Habitat: Found in farmland, wetter forest, woodland and basalt plains in the southwestern area of the MDB. Notes: A small cryptic frog that calls during autumn. The call is a series of low-pitched rasps. Eggs are laid singly beneath vegetation and leaf litter in soaked depressions after heavy rainfall. Tadpoles emerge from eggs following rainfall and undergo an aquatic development. Identification: Geocrinia laevis and G. victoriana overlap only in the Wimmera catchment and can be difficult to distinguish. Geocrinia laevis tends to have stronger colouring and markings than G. victoriana. Each species has a unique call. Conservation status: Not listed. MDB catchments: Wimmera.

Habitat: Found beneath vegetation in muddy depressions within a variety of habitats from alpine bogs, wet forest to dry woodlands in the southern area of the MDB. Notes: A small cryptic frog that calls during autumn. The call is a single harsh ‘squelch’, followed by a rapidly repeated, highpitched ‘pip-pip-pip’. Eggs are laid singly beneath vegetation and leaf litter in soaked depressions after heavy rainfall. Tadpoles emerge from eggs following rainfall and undergo an aquatic development. Identification: Geocrinia victoriana and G. laevis overlap only in the Wimmera catchment and can be difficult to distinguish. Geocrinia victoriana tends to have weaker colouring and markings than G. laevis. Each species has a unique call. Conservation status: Not listed. MDB catchments: Wimmera, LoddonAvoca, Campaspe, Goulburn-Broken, Ovens, Kiewa, Mitta Mitta.

This genus comprises seven species of stream breeding frogs from the rainforests and wet forests of eastern Australia. Three occur in the MDB. All species are very large, robust frogs with long and powerful hindlimbs with some degree of barring. They possess a vertical pupil and a distinct tympanum. A dark lateral stripe extends from the snout through the eye and over the top of the tympanum, which is disrupted by the nostril. The large body size, specific habitat, vertical pupil and degree of toe webbing make this group easily recognised.

yellow, with back of thighs black with pale yellow spots. Finger webbing absent and toes fully webbed. Habitat: Occurs among leaf litter in riparian rainforest and wet sclerophyll forest and now only known historically from the north-eastern MDB. Notes: Breeding occurs in rock pools with the call described as a deep guttural ‘wharrk’like grunt, usually as a single note. Eggs are flicked or scattered along overhanging rocks and creek banks. Tadpoles are large and dull gold with a distinct dark band across the base of the body. Identification: Mixophyes iteratus is distinguished from M. fasciolatus and M. fleayi by the combination of the very large size, scattered irregular blotching across the dorsum, iris being brown below pupil and gold above, and fully webbed toes. Conservation status: Endangered (NSW, nationally). MDB catchments: Condamine-Balonne, Border Rivers.

Also referred to as ‘brood frogs’ because their eggs are laid on land in damp nests, which are constructed and watched over by the males. The tadpoles hatch after rain and complete their development in water. Found mostly in association with small soaks and drainage lines within forested areas. Pseudophryne species superficially resemble Uperoleia species, which are distinguished by their strongly developed parotoid glands. Bibron’s Toadlet Pseudophryne bibronii TL: Males 22–30 mm; females 25–32 mm Description: Body small and squat with short, wide head and slightly pointed snout.

Toadlets (Genus Pseudophryne) Pseudophryne is a genus of 14 small terrestrial frogs referred to as ‘toadlets’ because of their superficial resemblance to European toads. Most species occur in the east and south-west of Australia, with seven species in the MDB. All species are small bodied with short limbs and walk more than hop. The head is short with a pointed or rounded snout and have only moderately developed parotoid glands. The eyes have a horizontal pupil and they lack a tympanum and middle ear structure.

Tree frogs (Family Pelodryadidae) Until recently, Australian and New Guinea tree frogs were considered a subfamily within the global family Hylidae but are now placed in their own regional family, Pelodryadidae. This family contains about one third of Australia’s frog fauna, having two genera Cyclorana and Litoria, with a third Nyctimystes occurring in New Guinea. Members of this family are loosely referred to as ‘tree frogs’, due to the fact many species have expanded finger and toe discs to assist in climbing. Many of the Litoria species climb trees and rocks but those in the genus Cyclorana lack any expanded finger and toe discs and are terrestrial, burrowing frogs.

Burrowing frogs (Genus Cyclorana) A group of medium-sized to large burrowing frogs distributed mainly through central and northern Australia. There are six species that occur in the central and northern MDB. They are usually observed only after rainstorms, gathering near temporary pools and inundated areas to breed. Tadpoles usually develop quickly in these conditions before the pools dry out. Cyclorana species do not have obvious discs or pads on the tips of their digits and the first finger is opposed to the remaining fingers. All have a prominent supratympanic skin fold, mostly large eyes and a horizontal pupil. The fingers are unwebbed and the toes are at least partially 74

Tree Frogs (Genus Litoria) The genus Litoria was erected in 1838 and is the largest Australian frog genus.

It has served as a convenient assemblage of Australian tree frogs regardless of their relatedness. The morphology of these frogs is highly variable between species and today we have a situation where the tiny Eastern Dwarf Frog (Litoria fallax) and the large common Green Tree Frog (Litoria caerulea) are members of the same genus. Frogs of the genus Litoria have finger and toe discs for climbing and this distinguishes them from the other Australian pelodryadid genus Cyclorana, which lacks finger and toe discs. Webbing between the fingers and toes can be present or absent and the pupil is horizontal in all species. Eggs are laid in water in all but one species, and tadpoles are fully aquatic. Taxonomic revisions continue to try and seek clarification of the relatedness of species in this genus and some published work has not been fully accepted. However, there is little doubt that the genus will be split into multiple genera in the near future. The various ‘species groups’ occupy a variety of different habitats from fastflowing forest streams and wetlands to arid creek lines. These groupings are represented in the MDB by bell frogs, rocky river frogs, large green tree frogs, bleating tree frogs, laughing tree frogs, whistling tree frogs, dwarf green tree frogs, red-eyed green tree frogs, rocket frogs, leaf green tree frogs and riverine tree frogs. They are grouped together for convenience and don’t necessarily reflect phylogenetic relationships to one another. There are 25 species in the MDB. 79

True toads (Family Bufonidae) Bufonidae is a large family containing the world’s ‘true toads’, typically characterised by large, robust, warty bodies with short muscular limbs. They occur throughout the world on most continents and the Cane Toad Rhinella marina is now the world’s most widely distributed ‘frog’.

Cane Toad (Genus Rhinella) The genus Rhinella contains more than 70 species in Central and South America. A single Australian species Rhinella marina was deliberately released in Queensland in 1935 to control cane beetles. This disastrous attempt at biological control has resulted in the infringement on the habitat of native wildlife. The Cane Toad produces a variety of toxins that are capable of rapidly killing many native predators if they consume the toad. It continues to spread and the actual impact on the Australian environment and possible reduction in native species caused by this invasive pest is not well understood.

Freshwater turtles

F R O G S A N D R E P T I L E S O F T H E M U R R AY – D A R L I N G B A S I N

Turtles and tortoises are differentiated by lifestyle and body structure. Tortoises are land-dwelling creatures with club feet and do not occur in Australia. Sea turtles are ocean-going with flippers, while freshwater turtles (sometimes referred to as terrapins) inhabit fresh water and have clawedwebbed feet. Most tortoises and turtles are declining around the world. Australia has a variety of freshwater turtles. Four species of freshwater turtles occur in the Murray–Darling Basin. Bell’s Turtle (Wollumbinia bellii) is listed as Vulnerable and the other three, Macquarie Turtle (Emydura macquarii), Snake-necked Turtle (Chelodina longicollis) and Broad-shelled

Turtle (Chelodina expansa) are Threatened in the southern Murray–Darling Basin. Researchers from New South Wales Office of Environment and Heritage sampled turtle populations in the Murray River and its floodplain from 1976 to 1982 following a wet period and in 2009–11 at the end of the most severe drought on record. The aim was to asses how three species of freshwater turtle in the MDB had responded to long-term decline in river flow and floodplain inundation due to climatic drying and water diversions. Catch per unit effort in baited hoop nets declined by 91% for the Snake-necked Turtle and 69% for the Macquarie Turtle, but did not change significantly for the Broad-shelled Turtle. In addition, total catches from a range of sampling methods revealed a significantly reduced proportion of juvenile Snake-necked and Macquarie Turtles in 2009–11, suggesting a fall in recruitment. Following on from this initial work, researchers from Arthur Rylah Institute recognised a high mortality rate among freshwater turtles in the mid-Murray River region. They reinvigorated research in this area and forged productive conservation management relationships with the Yorta Yorta people. Researchers helped the Yorta Yorta people to manage the health of freshwater turtle populations and learn a knowledge system that will assist in the plight of their totem, the Broad-shelled Turtle. The project also explored how science can learn more from Traditional Owner knowledge and how working collectively can bring these two knowledge systems together to care for wildlife.

This research revealed populations of all three species of turtles are dominated by adults and highlighted a concern that juveniles are not surviving. Fox predation of nests was recognised as a major issue. The community group Turtles Australia Inc., in conjunction with Western Sydney University, have been studying these three species of turtles for over 10 years. The study sites in the Loddon-Avoca Catchment includes Gunbower Island, Lake Chalm and Kerang Lakes in northern Victoria. They also partner with local catchment authorities, Indigenous Australians and other volunteers to protect turtle nests from predation. Foxes are by far the most serious threat to nests, digging up eggs and devouring them. Nest predation rates are>90% every year and declines in numbers are significant. Aside from some general fox control methods, little action is being taken to reduce predation on turtle nests. Natural predators such as birds and monitor lizards also eat eggs but not nearly as many as foxes. Nests are protected by placing 500 mm square plastic netting over the site and then held in place with tent pegs. The gaps in the netting are large enough to allow the hatchlings through as they emerge. Nests are examined after hatching and this economical method of nest protection has a high rate of success. Information, including nest sites, hatching rates, individual turtles both alive and dead are recorded on ‘Turtle SAT’: an application run by the Western Sydney University. Turtle SAT now has over 7000 records. Turtles Australia Inc. continues to protect 107

turtle nests, map nesting sites, raise awareness of turtle populations in regional areas, provide turtle nest protection kits to landholders and also present public talks and displays. Declining water availability may also be a widespread threat to freshwater turtles given predicted global impacts of climate change and water withdrawals on river flows. Freshwater turtles appear to be heading for extinction in the southern Murray–Darling Basin, with some local extinctions already occurring in South Australia.

Side-necked Freshwater Turtles (Family Chelidae) With only one exception, Australian freshwater turtles all belong to the family Chelidae. They are characterised by having clawed, webbed feet, eyes located high on the head and the nostrils close to the top of the mouth. The upper and lower parts of the shell are joined by a bridge: a rigid lateral extension joining the centre of the plastron to the carapace above. Horny epidermal shields cover the bony plates and are joined at the seams. The head is withdrawn side ways into the shell for protection.

Long-necked Turtles (Genus Chelodina) A genus containing seven species of the most distinctive Australian freshwater turtles easily recognised by their long necks and are also referred to as ‘snake-necked’ turtles. They occur throughout Australia, with two species in the MDB. The long neck is generally the length of the shell or longer and these turtles have powerful legs with four claws on each strongly webbed foot. If the turtle falls on its back it can quickly right itself with the use of the long neck. Some species can release a pungent odour when handled. All are oviparous and carnivorous, feeding on a variety of fish and aquatic invertebrates.

Short-necked Turtles (Genus Emydura) A genus with 15 proposed species of shortnecked turtles found in northern and eastern Australia. A single species occurs in the MDB. They have a broad carapace with a neck much shorter than the shell and five claws on the front and four on back of their strongly webbed feet. Most species usually have a pale streak on the side of the face. They are oviparous and omnivorous, feeding on a variety of fish, invertebrates and aquatic plants.

Legs powerful with strongly webbed, clawed feet. Habitat: Occurs in the river systems and associated wetlands throughout the MDB. Notes: A short-necked freshwater turtle often observed floating on the surface of the water during warm weather. Nesting occurs in conjunction with the first summer rainstorms from November to mid-December and an average of 20 hardshelled eggs are deposited in a hole dug by the female. During incubation, embryos may regulate development to hatch synchronously and emerge from the nest 111

together. The females probably use olfactory signals to guide nest site selection, preferring open nesting habitats and generally nest on higher ground, presumably to avoid flooding. Nest sites are usually riverbanks and sandhills. Identification: Emydura macquarii macquarii can be distinguished from the only other short-necked species of freshwater turtle in the MDB, Wollumbinia bellii, by the lack of pointed tubercles on the neck, lack of a thin horny shield on top on the head and non-serrated rear edges of the carapace in mature specimens.

F R O G S A N D R E P T I L E S O F T H E M U R R AY – D A R L I N G B A S I N

Australia has a diverse lizard fauna and the northern regions, along with the central and western deserts, have the highest species diversity and richest lizard habitats of anywhere in the world. Each family of Australian lizards is represented in the Murray–Darling Basin. They vary in size and appearance from the tiny Common Dwarf Skink (Menetia greyii) to the large and powerful, Lace Monitor (Varanus varius). Some lizard species in the MDB are threatened for various reasons. The direct disturbance or

reduction in habitat through livestock grazing and agriculture is the main threatening process in some areas. Feral animals, particularly foxes and cats, are well known for preying on lizards and the effects of fire frequency, intensity and extent are an important factor in reptile conservation. In the Victorian mallee of the southern Murray–Darling Basin, ‘management’ or ‘fuel reduction’ fires appear to have resulted in declines of the Mallee Tree Dragon (Amphibolurus norrisi).

trapping data, there are reports of a serious decline in this species from former habitat, with a concomitant increase in the Nobbi Dragon (Diporiphora nobbi), particularly in the southern Big Desert. It is unknown what impact this type of controlled burning has on the habitat of species with very disjunct distributions such as the Heath Monitor (Varanus rosenbergi). The clearing of woodlands for firewood, particularly River Red Gums, will have serious implications for the Lace Monitor (Varanus varius) that has a large home range and is dependent on old growth hollows for shelter and termite mounds for egg incubation. Some lizard species that occur in native grasslands have declined as their native grassland habitat is systematically destroyed. Natural temperate grasslands are considered to be one of the most threatened Australian ecosystems. The Grassland Earless Dragon (Tympanocryptis pinguicolla) from southern Victoria has not been sighted since 1969. Presently, the earless dragon that occurs near Canberra is assigned to this species, but will shortly be divided up into several other species. 118

Unless a near-miraculous rediscovery is made during current surveys for this lizard, the southern Victorian species may soon be declared extinct, which would be the first extinction of a reptile on the Australian mainland since white settlement. With the ongoing reduction of temperate grasslands in southern Victoria, similar habitat in the southern MDB will become even more important to species such as the Striped Legless Lizard (Delma impar). In the northern Murray–Darling Basin, the Condamine Earless Dragon (Tympanocryptis condaminensis) is now restricted to reduced grassland roadside verges and farmed areas. The Roma Earless Dragon (Tympanocryptis wilsoni) is classed as Vulnerable as it is known only from a small area of grassland, just west of Roma. Continued clearing of native vegetation in the Southern Brigalow Belt remains the greatest threat to reptiles in that region. Through the alpine regions of the Murray–Darling Basin, feral animals, particularly horses and deer, pose a threat to a variety of reptiles, due to destruction and degradation of habitat. Endangered skink species such as the Alpine She-oak Skink (Cyclodomorphus praealtus), Guthega Skink (Liopholis guthega) and Alpine Bog Skink (Pseudemoia cryodroma) are directly affected. The Guthega Skink appears far more vulnerable to threatening processes because it is more specialised and not as wide-ranging as the Alpine She-oak Skink. The Arthur Rylah Institute and Zoos Victoria have collaborated on a wild monitoring and captive breeding program to learn more about the behaviour, diet and reproduction of these two species.

The MDB still has some good areas of intact River Red Gum, Belah woodlands and mallee woodlands with spinifex that support numerous lizard species. These important habitats require careful, ongoing management, effective control of threatening processes and grazing, hydrological and fire regimes that are much better informed by the knowledge generated by conservation science. The following lizard species are found in the region: • Carphodactylidae (southern padless geckos): 5 species • Diplo dac t y lidae (diplo d ac ty lid geckos): 23 species • Gekkonidae (cosmopolitan geckos): 7 species • Pygopodidae (flap-footed Lizards): 15 species • Scincidae (skinks): 104 species • Agamidae (dragons): 21 species • Varanidae (monitors/goannas): 5 species

Southern padless geckos (Family Carphodactylidae) This group is the only endemic family of geckos in Australia. They are widespread with ~30 species. All are large geckos with a flattened or rounded head and have long slender limbs and padless, clawed digits. Most species have spectacular tails ranging from leaf shaped and carrot shaped to a tail with a bulbous knob. The eyes are cleaned using the long fleshy tongue. All species are oviparous, producing two soft-shelled eggs. Prey items include a range of invertebrates.

Knob-tailed Geckos (Genus Nephrurus) A distinctive genus of nine species containing ‘smooth’ and ‘rough’ knobtailed geckos. They are distributed throughout Australia and have large heads, plump bodies, big eyes, slender limbs and a short, fat tail, terminating in a small knob. Only one species of smooth knob-tailed gecko occurs in the MDB. Smooth Knob-tailed Gecko Nephrurus levis levis

Cosmopolitan geckos (Family Gekkonidae)

This large family of geckos is the most widespread in the world, ranging through tropical areas but also extending into cooler regions. Australian species are small to medium-sized with soft, velvety skin and capable of using their long fleshy tongue to clean the clear spectacle of their lidless eyes. The soft tail has fracture points and breaks easily. They are able to vocalise usually in the form of a squeak or chirrup. Gekkonids produce hard-shelled eggs that are impervious to moisture and generally two at a time. They are primarily nocturnal and feed on a variety of invertebrates but are also recorded lapping sap.

Skinks (Family Scincidae)

The skinks are widespread in the world and the largest family of Australian lizards, with 437 species currently described. They occur through a great diversity of habitats from cool alpine grasslands to hot arid regions and vary considerably in size and form. All are mostly terrestrial and diurnal. The majority of species have four limbs with five fingers and toes and a fragile tail that is easily broken. Many burrowing species are elongated with greatly reduced limbs and digits. Some species have eye lids, others a clear fixed spectacle or a movable lid enclosing a transparent disc. Skinks are mostly smoothscaled though some are spinose and others have large rugose scalation. They may be carnivorous or omnivorous. Some species are oviparous and others are livebearers. Skinks are well  represented in the MDB with 104 species recorded.

Spiny skinks, Yakka Skink, crevice skinks (Genus Egernia) This group comprises 17 medium-sized to very large skinks that are found throughout various habitats across Australia. Seven species occur in the MDB. This genus contains species that are quite different in appearance with scalation, ranging from smooth to striated and spinose. They are placed in species groups based on appearance and habits for ease of identification, but this does not necessarily reflect any relatedness. All are robust species with four well-developed limbs, each with five digits, and a movable, scaly lower eyelid. They are largely gregarious and all species are livebearing. Egernia rugosa is similar to Bellatorias and Tiliqua species, but those large skinks each have unique colours and patterns.

Spiny skinks (Genus Egernia) There are seven species of spiny skinks found throughout Australia, which generally occur in association with rock outcrops or in tree hollows. They have spines that protrude from the dorsal scalation and are capable of pushing their body hard up against the surrounding surface, making it very difficult for a predator to dislodge them.

Dragons (Family Agamidae)

Dragon lizards occur from the western Pacific, through Australia, Asia to Africa and Europe. There are 89 species recorded from Australia, with 21 species in the MDB. Most occur in arid and semi-arid open habitat. The majority of species are terrestrial, though some are arboreal and even semi-aquatic. They are broadly similar with four limbs each with five clawed digits and rough scalation often with tubercles and spines. They have a movable, scaly eyelid. Smaller species feed on invertebrates while larger species tend to be omnivorous. All Australian species are oviparous, producing from two to 30 soft-shelled eggs that are deposited in a burrow dug by the female. They are diurnal, sun loving lizards and can be found throughout the MDB.

Monitor lizards/goannas (Family Varanidae) Monitors occur from the western Pacific, through Australia, Asia and Africa. This family contains the largest lizards in the world. There are 30 species recorded from Australia and are known as goannas (a corruption of the word ‘iguana’). They range in size from small arboreal species to large and powerful terrestrial species and all Australian members of the family Varanidae belong to the genus Varanus.

Monitor lizards/goannas (Genus Varanus) Active, diurnal lizards found throughout Australia, with five species recorded from the MDB. The species are broadly similar and easily recognised by their long flat head, long neck and a conspicuous tympanum. They have four strong limbs, each with five sharp, clawed digits. The tongue is long and deeply forked and continually flicked in and out while foraging. They have a long slender tail, which the larger species use as a defensive weapon. All species are oviparous, producing clutches of up to 35 soft-shelled eggs. They are carnivorous, consuming anything that can be overpowered and their diet also includes carrion.

Australia has a reputation for having many species of dangerous snakes. Although it is true that many Australian species have potent venom, there are also many other types of snakes ranging from small, harmless, burrowing blind snakes that feed on ants to large pythons that overpower their prey items through constriction. Snakes are an important part of ecosystems and it can be difficult to accurately assess the threatening processes, but certainly land clearing for grazing and agriculture is a serious concern. Drying out of wetlands that do not receive periodic flooding will seriously impact frogs, a main food item for many snakes. The implementation of correct fire regimes appears to be another important factor. Feral animals also play a major role in the declines of snakes through direct predation, competition for prey items and habitat disturbance.

The Murray–Darling Carpet Python (Morelia spilota metcalfei) is Endangered in the southern part of its range as its habitat has been reduced and divided through land clearing, logging and firewood collection. In particular, the loss of River Red Gums along the Murray River is continuing to cause the reduction of preferred habitat. Foxes, cats and dogs are also implicated in the decline of this iconic species. Natural fire regime is the pattern, frequency and intensity of fires that prevail in an area over long periods of time and is considered an integral part of fire ecology and renewal for certain types of ecosystems. However, too frequent and extensive burns, supposedly to reduce fuel, may have a devastating impact on certain species of reptiles.

Basin, appears to have declined precipitously in areas that have undergone ‘management’ burning. Conversely, pitfalltrapping has produced specimens in areas of old growth spinifex with leaf litter and ground cover that have not been subjected to controlled burning. The Mud Adder or De Vis’ Banded Snake (Denisonia devisi) is well known in the northern MDB but its presence in the south-western area of the Basin was confirmed only in recent times. This species is known only from a small area and is possibly an isolated population. It is Critically Endangered in Victoria. In 1857, museum collector and herpetologist, Gerard Krefft recorded a specimen of the Common Death Adder (Acanthophis antarcticus) at Lake Boga in northern Victoria. This is the only specimen of a Common Death Adder known from Victoria and represents the most southerly record for the Murray–Darling Basin. A variety of snakes occur in the MDB and a deep-seated fear of snakes was no doubt ingrained in the early settlers of this region. An image taken in 1906 shows a snake hunt on the Murray River resulting in the deaths of many snakes, in just one day.

Some notable records of dangerous snakes are specimens of the Inland Taipan (Oxyuranus microlepidotus) collected at ‘Mondellium’, a camp site near the junction of the Murray and Darling rivers during a museum collecting trip in 1857. Apart from a possible record at Tindaree in NSW, this dangerously venomous snake (considered to be the most venomous land snake in the world) otherwise appears to be restricted to the Lake Eyre Basin. The Eastern Brown Snake (Pseudonaja textilis) is a highly defensive species and responsible for more bites in Australia than other venomous snake species. It is widespread and has no doubt prospered from wheat farming in the Mallee areas of the southern Murray–Darling-Basin, due to generalised habitat preferences and a diet that includes introduced rodents. There are 13 dangerously venomous snakes in the MDB capable of inflicting a lethal bite: • Common Death Adder Acanthophis antarcticus • Highlands Copperhead Austrelaps ramsayi • Lowlands Copperhead Austrelaps superbus • Eastern Small-eyed Snake Cryptophis nigrescens • Mainland Tiger Snake Notechis scutatus scutatus • Inland Taipan Oxyuranus microlepidotus • Mulga Snake Pseudechis australis • Spotted Black Snake Pseudechis guttatus • Red-bellied Black Snake Pseudechis porphyriacus • Strap-snouted Brown Snake Pseudonaja aspidorhynca

SNAKES

• Western Brown Snake Pseudonaja mengdeni • Eastern Brown Snake Pseudonaja textilis • Rough-scaled Snake Tropidechis carinatus The incidence of snakebite in Australia is low, with most people being bitten by snakes only when they interfere with them. The death rate from snakebite in Australia averages only one to two persons per year. In the event of a dangerous snakebite, first aid should be immediately (see Box) applied and the patient hospitalised as soon as possible. Snakebite antivenom is available for all Australian dangerous species.

Pressure and immobilisation first aid method for snakebite

• Apply a broad pressure bandage from below the bite site, upwards on the affected limb. Leave the tips of the fingers or toes unbandaged to allow the patient’s circulation to be checked. Do not remove clothing: bandage over the clothes. • Bandage firmly (as for a sprain), which is tight enough to compress the lymphatic vessels but not enough to prevent circulation. • If possible, bind a splint to the bitten limb to prevent further movement. Seek medical assistance immediately. The following families of snakes occur in the MDB region: • Typhlopidae (blind snakes) 11 species • Pythonidae (pythons) 5 species

Blind snakes (Family Typhlopidae)

This is a group of poorly understood, harmless burrowing snakes that are distributed in the warmer parts of the world. They occur throughout Australia except in the lower south-eastern mainland and Tasmania. All endemic Australian species belong to the genus Anilios. A single introduced species, the Flowerpot Snake Indotyphlops braminus, is becoming more established in coastal areas.

Australasian blind snakes (Genus Anilios) This genus contains 45 Australian species of worm-like snakes with eyes reduced to dark spots on the top of a blunt head. Eleven species are recorded from the MDB. The snout may be smoothly rounded or sharply beaked and the small mouth is set back from the snout. They have glossy scales and a short tail, which, in all but one species, terminates in a spine. If handled, an offensive substance can be released from their cloacal glands. They are oviparous. These are Australia’s only insectivorous snakes, feeding on termites and the eggs, larvae and pupae of ants. Small-headed Blind Snake Anilios affinis TL: 220 mm Description: Body slender with short blunt tail. Dorsum dark brown to pinkish brown merging on to the lower flanks. Head pale with a bluntly rounded snout from above. Mid-body scale rows: 18. Ventral area pale

Pythons (Family Pythonidae)

Pythons are the largest living snakes and are distributed mostly through tropical areas of Sub-Saharan Africa, Asia, New Guinea and Australia. They are well known for their ability to swallow large prey, which they overpower by means of constriction. All pythons are non-venomous with solid curved teeth. Most have heat sensitive pits along the lips to assist in the detection of warm-blooded animals. They have a pair of cloacal spurs on either side of the vent, which is larger in males than females. Pythons are mostly nocturnal but also encountered basking during the day. They are oviparous, producing soft-shelled eggs and the female usually coils around the clutch to assist with incubation by generating heat internally through muscular ‘shivering’.

Spotted Python Antaresia maculosa TL: 1.05 m Description: Body robust with short tapering tail. Dorsum pale brown to chocolate brown or purplish brown with pattern of ragged-edged darker brown blotches, paler on lower flanks. Head light brown and elongated with square-shaped snout. Dark streak through each eye and pale lips. Ventral area whitish. Scales

Terrestrial pythons (Genus Antaresia) This genus contains four species of Australia’s smallest pythons that are widespread from arid and semi-arid areas to tropical woodlands and rainforest margins. Two are recorded from within the MDB. They feed on a variety of reptiles, frogs, mammals and birds. Heat sensory pits are located on some lower scales but not in the rostral. The head is covered with large symmetrical shields and there are three or more loreal scales.

Venomous land snakes (Family Elapidae)

This is a widespread family distributed through Africa, Asia, Australia and the Americas, containing the most venomous species of snakes in the world. Terrestrial elapid snakes reach their greatest diversity in Australia, with 106 described species. They have a fixed immovable, relatively short fang at the front of the upper jaw. It is connected at the base to a venom gland via a duct. The venom of Australian elapid snakes is largely neurotoxic but in some species it is more haemotoxic. Features of elapids include enlarged symmetrical scales on top of the head, large ventral scales and lack of a loreal scale. Some are oviparous and others livebearing: the latter trait being almost exclusive to Australasian species. Of the 40 elapid snakes that occur in the MDB, 13 are dangerously venomous but all species should be treated with caution.

Common Death Adder Acanthophis antarcticus TL: 700 mm Description: Body short and robust with slender tail terminating in soft spine.

and moderately large eyes with a round pupil. Prey items include frogs, lizards, birds and small mammals. It is livebearing. It is most likely to be confused with the harmless Keelback, Tropidonophis mairii, but that species has the anal and subcaudal scales divided and a loreal scale present. It could also be confused with the Tiger Snake Notechis scutatus, but that species has smooth scalation and fewer mid-body scales rows. Rough-scaled Snake Tropidechis carinatus TL: 900 mm Description: Body large and robust with slender tail. Dorsum yellowish brown to dark brown and olive, usually with irregular

narrow dark crossbands. Some individuals plain coloured. Head long, slightly distinct from neck, with moderately rounded snout. Ventral area cream, yellow or olive-green, often with numerous darker blotches. Scales keeled and in 23 rows at mid-body. Ventrals: 160–185. Anal scale single. Subcaudals: 50–60, all single. Habitat: Generally encountered around streams and swamps in wet sclerophyll forest and rainforest in the north-eastern MDB. Notes: Nocturnal and diurnal. Mostly terrestrial, but readily climbs into low foliage to bask. Livebearing with litters of five to eight young recorded. A nervous and very dangerous snake, quickly becoming aggressive if disturbed. Dangerously venomous. Identification: Tropidechis carinatus can be identified by having 23 mid-body scale rows and single anal and subcaudal scales. Conservation status: Not listed. MDB catchments: Condamine-Balonne.

Bandy bandys (Genus Vermicella) This genus contains five species of black and white ringed burrowing snakes distributed throughout Australia. One species is widespread in the MDB.
