The Red Kangaroo is the largest macropod and is Australia's heraldic animal, appearing on the Coat of Arms of Australia. The fauna of Australia comprises a huge variety of unique animals; some 83% of mammals, 89% of reptiles, 90% of fish and insects and 93% of amphibians that inhabit the continent are endemic.[1] This high level of endemism can be attributed to the continent's long geological isolation, tectonic stability, and the effects of an unusual pattern of climate change on the soil and flora over geological time. A unique feature of Australia's fauna is the relative scarcity of native placental mammals. Consequently the marsupials, a group of mammals that raise their young in a pouch including the macropods, possums and dasyuromorphs, mostly fill the ecological niches that are occupied by placental mammals elsewhere in the world. Australia is home to the two of the five extant egg-laying monotremes, and has numerous venomous species, which include the monotremes, spiders, scorpions, octopuses, jellyfish, molluscs, stonefish, stingrays. Uniquely, Australia has more venomous than non-venomous species of snakes. The settlement of Australia by Indigenous Australians more than 40,000 years ago, and by Europeans from 1788, has had a significant impact on the fauna. Hunting, the introduction of non-native species and land-management practices involving the modification or destruction of habitats have led to numerous extinctions, some examples include the Paradise Parrot, Pig-footed Bandicoot and the Broad-faced Potoroo. Unsustainable land use continues to threaten the survival of many species. In recognition of the threats to the survival of its fauna, Australia has passed wide-ranging federal and state legislation and has established numerous protected areas to protect the fauna. However, many people believe that these measures fail to address the immanent threats to the survival of many species.

Several reasons for the uniqueness of Australia's fauna have been advanced. Australia was once part of the southern supercontinent Gondwana, which also included South America, Africa, India and Antarctica. Gondwana began to break up 140 million years ago (MYA); 50 MYA Australia separated from Antarctica, and was relatively isolated until the collision of the Indo-Australian Plate with Asia in the Miocene era 5.3 MYA. The establishment and evolution of the present-day fauna was apparently shaped by the unique climate and the geology of the continent. As it drifted, Australia was, to some extent, isolated from the effects of global climate change, and the unique fauna that originated in Gondwana, like the marsupials, was conserved and radiated in Australia. After the Miocene, fauna of Asian origin were able to establish themselves in Australia. The Wallace Line—the hypothetical line separating the zoogeographical regions of Asia and Australasia—marks the tectonic boundary between the Eurasian and Indo-Australian plates. This continental boundary prevented the formation of land bridges, which explains the distinct zoological distribution and limited overlap of most Asian and Australian fauna, with the exception of birds. Following the emergence of the circumpolar current in the mid-Oligocene era (some 15 MYA), the Australian climate became increasingly arid, giving rise to a diverse group of arid-specialised organisms, just as the wet tropical and seasonally wet areas have produced their own adapted species. Mammals Australia has a rich mammalian fossil history, and a varied group of extant species dominated by the marsupials. The fossil record shows that monotremes have been present in Australia since the Early Cretaceous 145–99 MYA [2], and that marsupials and placental mammals date from the Eocene 56–34 MYA [3], when modern mammals first appeared in the fossil record. Although marsupials and placental mammals did coexist in Australia in the Eocene, only marsupials have survived to the present. The placental mammals made their reappearance in Australia in the Miocene as Australia moved closer to Indonesia, and bats and rodents started to appear reliably in the fossil record. Marsupials evolved to fill similar niches and are in many cases physically similar to their placental counterparts in Eurasia and North America, which occupy similar ecological niches in a phenomenon known as convergent evolution.[4] For example, the top predator in Australia, the Tasmanian Tiger, bore a striking resemblance to canids such as the Gray Wolf; gliding possums and flying squirrels have similar adaptations enabling their arboreal lifestyle; and Numbat and anteaters are both digging insectivores. Monotremes and marsupials The Platypus is one of a small group of venomous mammals. Two of the five living species of monotreme occur in Australia: the Platypus and the Short-beaked Echidna. The monotremes differ from other mammals in their methods of reproduction; in particular, they lay eggs instead of giving birth to live young. The Platypus — a venomous, egg-laying, duck-billed amphibious mammal — is considered to be one of the strangest creatures in the animal kingdom. When it was first presented by Joseph Banks to English naturalists it was thought to be so strange that it was a cleverly created hoax. The Short-beaked Echidna is similarly strange, covered in hairy spikes with a tubular snout in the place of a mouth, and a tongue that can move in and out of the snout about 100 times a minute to capture termites. The Spotted Quoll is mainland Australia's largest carnivorous marsupial and an endangered species. Australia has the world's largest and most diverse range of marsupials. Marsupials are characterised by the presence of a pouch in which they rear their young. The carnivorous marsupials—order Dasyuromorphia — are represented by two surviving families: the Dasyuridae with 51 members, and the Myrmecobiidae with the numbat as its sole surviving member. The Tasmanian Tiger was the largest Dasyuromorphia and the last living specimen of the family Thylacinidae; however, what appears to have been the last known specimen died in captivity in 1936. The world's largest surviving carnivorous marsupial is the Tasmanian Devil; it is the size of a small dog and can hunt, although it's mainly a scavenger. It became extinct on the mainland some 600 years ago, and is now found only in Tasmania. There are four species of quoll, or native cat, all of which are threatened species. The remainder of the Dasyuridae are referred to as 'marsupial mice'; most weigh less than 100 g. There are two species of Marsupial Mole — order Notoryctemorphia — that inhabit the deserts of Western Australia. These rare, blind and earless carnivorous creatures spend most of their time underground; little is known about them. The Sugar Glider. The bandicoots and bilbies — order Peramelemorphia — are marsupial omnivores. There are seven species in Australia, most of which are endangered. These small creatures share several characteristic physical features: a plump, arch-backed body with a long, delicately tapering snout, large upright ears, long, thin legs, and a thin tail. The evolutionary origin of this group is unclear, because they share characteristics from both carnivorous and herbivorous marsupials. The Koala does not normally need to drink, because it can obtain all of the moisture it needs by eating leaves. Herbivorous marsupials are classified in the order Diprotodontia, and further into the suborders Vombatiformes and Phalangerida. The Vombatiformes include the Koala and the three species of wombat. One of Australia's best-known marsupials, the Koala is an arboreal species that feeds on the leaves of approximately 120 species of eucalyptus. Wombats, on the other hand, live on the ground and feed on grasses, sedges and roots. Wombats use their rodent-like front teeth and powerful claws to dig extensive burrow systems; they are mainly crepuscular and nocturnal. The Phalangerida includes six families and 26 species of possum and three families with 51 species of macropod. The possums are a diverse group of arboreal marsupials and vary in size from the Little Pygmy Possum, weighing just 7 g, to the cat-sized Common Ringtail and Brushtail possums. The Sugar and Squirrel Gliders are common species of gliding possum, found in the eucalypt forests of eastern Australia, while the Feathertail Glider is the smallest glider species. The gliding possums have membranes called 'patagiums' that extend from the fifth finger of their forelimb back to the first toe of their hind foot. These membranes, when outstretched, allow them to glide between trees. The macropods are divided into three families: the Hypsiprymnodontidae, with the Musky Rat-kangaroo as its only member; the Potoroidae, with 10 species; and the Macropodidae, with 40 species. Marcopods are found in all Australian environments except alpine areas. The Potoroidae include the bettongs, potaroos and rat-kangaroos, small species that make nests and carry plant material with their tails. The Macropodiae include kangaroos, wallabies and associated species; size varies widely within this family. Most macropods have large hind legs and long, narrow hind feet, with a distinctive arrangement of four toes, and powerfully muscled tails, which they use to move in a bipedal, energy-efficient hopping motion. The short front legs have five separate digits. The Musky Rat-kangaroo is the smallest macropod and the only species that is not bipedal, while the male Red Kangaroo is the largest, reaching a height of about 2 m and weighing up to 85 kg. Placental mammals The Dingo was the first placental mammal introduced to Australia by humans. Australia has indigenous placental mammals from two orders: the bats — order Chiroptera — represented by six families; and the mice and rats—order Rodentia, family Muridae. Bats and rodents are relatively recent arrivals to Australia; bats are present in the fossil record only from as recently as 15 MYA, and probably arrived from Asia. There are only two endemic genera of bats, although 7% of the world's bats species live in Australia. Rodents first arrived in Australia 5–10 MYA and underwent a wide radiation to produce the species collectively known as the 'old endemic' rodents. The old endemics are represented by 14 extant genera. A million years ago, the rat entered Australia from New Guinea and evolved into seven species of Rattus, collectively called the 'new endemics'. Since human settlement, many placental mammals have been introduced to Australia and are now feral. The first animal introduced to Australia was the Dingo. Fossil evidence suggests that people from the north brought the Dingo to Australia about 5000 years ago. [5] When Europeans settled Australia they intentionally released many species into the wild including the Red Fox, Brown Hare, and the European Rabbit. Other domestic species have escaped and over time have produced wild populations including the cat, Fallow Deer, Red Deer, Sambar Deer, Rusa Deer, Chital, Hog Deer, Domestic Horse, Donkey, Pig, Domestic Goat, Water Buffalo, Blackbuck and the Dromedary. Only three species of placental mammal were not deliberately introduced to Australia, the House Mouse, Black Rat and the Brown Rat. The Dugong is an endangered species; the largest remaining population is found in Australian waters. Forty-six marine mammals from the order Cetacea are found in Australian coastal waters. Since the majority of these species have global distribution, some authors do not consider them Australian species. There are nine species of baleen whale present, including the enormous Humpback Whale. There are 37 species of toothed whale, which include all six genera of the family Ziphiidae, and 21 species of oceanic dolphin, including the Australian Snubfin Dolphin, a species first described in 2005. Some oceanic dolphins, such as the Orca, can be found in all waters around the continent; others, such as the Irrawaddy Dolphin, are confined to the warm northern waters. The Dugong is an endangered marine species that inhabits the waters of northeastern and northwestern Australia, particularly the Torres Strait. It can grow up to 3 m long and weigh as much as 400 kg. The dugong is the only herbivorous marine mammal in Australia, feeding on sea grass in coastal areas. The destruction of sea grass beds is a threat to the survival of this species. Eleven species of seal — family Pinnipedia — live off the southern coast. Birds The Emu is the second largest surviving species of bird. It is a heraldic bird, appearing on the Coat of Arms of Australia. Australia and its territories are home to over 800 species of bird; about 350 of these are endemic to the zoogeographic region that covers Australia, New Guinea and New Zealand. The fossil record of birds in Australia is patchy; however, there are records of the ancestors of contemporary species as early as the Late Oligocene.[6] Birds with a Gondwanan history include the flightless ratites (the Emu and Southern Cassowary), megapodes (the Malleefowl and Australian Brush-turkey), and a huge group of endemic parrots (order Psittaciformes). Australian parrots comprise a sixth of the world’s parrots, including many cockatoos and galahs. The Kookaburra is the largest species of the kingfisher family, which has a long history in Australia. Passerine, peculiar to Australasia, are descended from the ancestors of the Crow (Corvi). Examples include wrens, robins, the magpie group, thornbills, pardalotes, the huge honeyeater family, treecreepers, lyrebirds, birds of paradise and bowerbirds. The Satin Bowerbird is a fascinating case that has attracted the interest of evolutionary psychologists: it has a complex courtship ritual in which the male creates a bower filled with blue, shiny items to woo mates. A female Gang-gang Cockatoo. Relatively recent colonists from Eurasia are swallows, larks, thrushes, cisticolas, sunbirds, and some raptors, including Australia's raptor, the Wedge-tailed Eagle. A number of bird species have been introduced by humans: some, like the European Goldfinch and Greenfinch, coexist happily with Australian species; others, such as the Common Starling, European Blackbird, House Sparrow and Indian Mynah, are destructive of some native bird species and thus destabilise the native ecosystem. About 200 species of seabird live on the Australian coast, including many species of migratory seabird. Australia is at the southern end of the East Asian-Australasian flyway for migratory water birds, which extends from Far-East Russia and Alaska through Southeast Asia to Australia and New Zealand. About two million birds travel this route to and from Australia each year. A large and very common seabird is the Australian Pelican, which can be found in most waterways in Australia. The Little Penguin is the only species of Penguin that breeds on mainland Australia. Amphibia and reptiles The Eastern Banjo Frog is a common frog species across eastern Australia. Australia has four families of native frogs and one introduced toad, the Cane Toad. In a disastrous decision in 1935, the Cane Toad was introduced to Australia in a failed attempt to control pests in sugarcane crops, and has since become a devastating pest, spreading across northern Australia. As well as competing with native insectivores for food, the Cane Toad produces a venom through parotoid glands that is toxic to native fauna, as well as humans. The Myobatrachidae, or southern frogs, are Australia's largest group of frogs, with 120 species from 21 genera. A notable member of this group is the colourful and endangered Corroboree Frog. The tree frogs, from family Hylidae, are common in high rainfall areas on the north and east coasts; there are 77 Australian species from three genera. The 18 species from two genera of the Microhylidae frogs are restricted to the rainforests; the smallest species, the Scanty Frog, is from this family. There is a single species from the world's dominant frog group, family Ranidae — the Australian Wood Frog — which only occurs in the Queensland rainforests. As elsewhere, there has been a precipitous decline in Australia's frog populations in recent years; although the full reasons for the decline are uncertain, it can be at least partly attributed to the fatal amphibian fungal disease chytridiomycosis. The Saltwater Crocodile is the World's largest reptile. Australia has both saltwater and freshwater crocodiles. The Saltwater Crocodile, known colloquially as the 'salty', is the largest living crocodile species; reaching up to 7 m and weighing up to 1000 kg, they can and do kill humans. They live on the coast and in the freshwater rivers and wetlands of northern Australia, and they are farmed for their meat and leather. Freshwater Crocodiles are found only in the freshwater waterways of Northern Australia, and are not considered dangerous to humans. The Australian coast is visited by six species of sea turtle: the Flatback, Green Sea, Hawksbill, Olive Ridley, Loggerhead and the Leatherback Sea Turtles; all are protected in Australian waters. There are 29 species of Australian freshwater turtles from eight genera of family Chelidae. The Australasian Pig-Nose Turtle is the only Australian member of that family. Australia and Antarctica are the only continents without any living species of land tortoise. Blue-tongued lizards are the largest species of skink. Australia is the only continent where venomous snakes outnumber their non-venomous cousins. Australian snakes belong to seven families, of these the most venomous species including the Fierce Snake, Eastern Brown Snake, Taipan and Eastern Tiger Snake are from the family Elapidae. Of the 200 species of elapid, 86 are found only in Australia. Thirty-three sea snakes from family Hydrophiidae inhabit Australia's northern waters; many are extremely venomous. Two species of sea snake from the Acrochordidae also occur in Australian waters. Australia has only 11 species from the world's most significant snake family Colubridae; none are endemic, and they are considered to be a relatively recent arrival from Asia. There are 15 species of boa, and 31 species of insectivorous blind snake. There are more lizards in Australia than anywhere else in the world, with representatives of five families. There are 114 species in 18 genera of gecko found throughout the Australian continent, but not in Tasmania. The Pygopodidae is a family of limbless lizards endemic to the Australian region; of the 34 species from eight genera, only one species does not occur in Australia. The Agamidae or Dragon lizards are represented by 66 species in 13 genera, including the Thorny Devil, Bearded Dragon and Frill-necked Lizard. There are 26 species of monitor lizard, family Varanidae, in Australia, where they are commonly known as goannas. The largest Australian monitor is the Perentie, which can reach up to 2 m in length. There are 389 species of skink from 38 genera, comprising about 50% of the total Australian lizard fauna; this group includes the blue-tongued lizards. Fish Main article The Queensland Lungfish normally uses its gills for respiration, but is also capable of taking in oxygen from the air. More than 4400 species of fish inhabit Australia's waterways;[7] of these, 90% are endemic. Australia has a relatively small freshwater fish fauna of only 170 species—this may be related to the relative scarcity of freshwater waterways in the continent. Two families of freshwater fish have ancient origins: the Queensland Lungfish and the bony tongues. The Queensland Lungfish is most primitive of the lungfish, having evolved before Australia separated from Gondwana. The Salamanderfish, peculiar to the south-west of Western Australia, is one of the smallest freshwater fish and can survive desiccation in the dry season by burrowing into mud. Other families with a potentially Gondwanan origin include the Retropinnidae, Galaxiidae, Aplochitonidae and Percichthyidae. Apart from the ancient freshwater species, 70% of Australia's freshwater fish have affinities with tropical Indo-Pacific marine species that have adapted to freshwater.[8] Nevertheless, fossil evidence indicates that many of these freshwater species are still ancient in origin. These species include freshwater lampreys, herrings, catfish, rainbowfish, and some 50 species of gudgeon, including the Sleepy Cod. Native freshwater game fish include the Barramundi, Murray Cod, and Golden Perch. Two species of freshwater shark are found in the Northern Territory, both endangered. A number of exotic freshwater fish species, including Brown, Brook and Rainbow Trout, Atlantic and Chinook Salmon, Redfin Perch, Carp and Mosquitofish, have been introduced to Australian waterways with serious detrimental effects.[9] The Mosquitofish is a particularly aggressive species known for harassing and nipping the fins of other fish and has been linked to declines and/or localised extinctions of a number small native fish species. The predatory introduced trout species have had serious negative impacts on a number of upland native fish species including Trout Cod, Macquarie Perch and Galaxias species as well as other upland fauna such as the Spotted Tree Frog. The Carp is strongly implicated in the dramatic loss in waterweed and permanently elevated levels of turbidity in the Murray-Darling system. Weedy Sea Dragon is found in waters around southern Australia. Most of Australia's fish species are marine. Groups of interest include the Moray eels, squirrelfish, pipefish and seahorses, whose males incubate the eggs in a specialised pouch. There are 80 species of grouper in Australian waters, including one of the world's biggest bony fish—the Giant Grouper—which can grow as large as 2.7 m and weigh up to 400 kg. The trevally, a group of 50 species of silver schooling fish, and the snappers are popular species for commercial fishing. The Great Barrier Reef supports a huge variety of small- and medium-sized reef fish, including the damselfish, butterflyfish, angelfish, gobies, cardinalfish, wrasse, triggerfish and surgeonfish. There are a number of venomous fish, among them several species of stonefish and pufferfish and the Red Lionfish, all of which have toxins that can kill humans. There are 11 venomous species of stingray, the largest of which is the Smooth Stingray. The barracudas are one of the reef's largest species; large reef fish should not be eaten for fear of ciguatera poisoning. The Spotted Wobbegong is the largest wobbegong shark, reaching a length of 3.2 m. Sharks inhabit all the coastal waters and estuarine habitats of Australia’s coast. There are 166 species, including 30 species of requiem shark, 32 of catshark, six of wobbegong shark, and 40 of dogfish shark. There are three species from the family Heterodontidae: the Port Jackson Shark, the Zebra Horn Shark and the Crested Horn Shark. In 2004, there were 12 unprovoked shark attacks in Australia, of which two were fatal.[10] Only 3 species of shark pose a significant threat to humans: the Bull shark, the Tiger Shark and the Great White Shark. Some popular beaches in Queensland and New South Wales are protected by shark netting, a method that has reduced the population of both dangerous and harmless shark species through accidental entanglement. The overfishing of sharks has also significantly reduced shark numbers in Australian waters, and several species are now endangered. A Megamouth Shark was found on a Perth beach in 1988; very little is known about this species, and this discovery may indicate the presence of the species in Australian coastal waters. Invertebrates Taxonomic group Estimated number of species described Estimated total number of species in Australia Porifera 1,416 ~3,500 Cnidaria 1,270 ~1,760 Platyhelminthes 1,506 ~10,800 Acanthocephala 57 ~160 Nematoda 2,060 30,000 Mollusca 9,336 ~12,250 Annelida 2,125 ~4,230 Onychophora 56 ~56 Crustacea 6,426 ~9,500 Arachnida 5,666 ~27,960 Insecta 58,532 ~83,860 Echinodermata 1,206 ~1,400 Other invertebrates 2,929 ~7,230 Modified from: Williams et al. 2001.[1] Of the estimated 200,000 animal species in Australia, about 96% are invertebrates. While the full extent of invertebrate diversity is uncertain, 90% of insects and molluscs are considered endemic. [1] Invertebrates occupy many ecological niches and are important in all ecosystems as decomposers, pollinators, and food sources. The largest group of invertebrates is the insects, comprising 75% of Australia's known species of animals. The most diverse insect orders are the Coleoptera, with 28,200 species of beetles and weevils out of an estimated 300,000 worldwide. There are 20,816 species of Lepidoptera, including butterflies and moths, out of an estimated 100,000, and 12,781 species of Hymenoptera, the order that included the ants, bees and wasps from 100,000 worldwide. Order Diptera, which includes the flies and mosquitoes, comprises 7,786 species out of 150,000; and of the estimated 60,000 species of Hemiptera (including bugs, aphids and hoppers), 5,650 are found in Australia. There are 2,827 species of order Orthoptera, including grasshoppers, crickets and katydids, out of an estimated global total of 20,000.[11] Introduced species that pose a significant threat to native species include the European Wasp, the Red Fire Ant, the Yellow Crazy Ant and feral honeybees which compete with native bees. There are 1,275 described species and subspecies of ant from Australia.[12] This species is the Australian bull ant. Australia has a wide variety of arachnids, including 135 species of spider that are familiar enough to have common names. There are a number of highly venomous species, including the notorious Sydney Funnel-web and Red-back spiders, whose bite can be deadly. There are thousands of species of mites and ticks from order Acarina. Australia also has eight species of pseudoscorpion and nine scorpion species. There are two families of native terrestrial worms: the Enchytraeidae, and the Megascolecidae that includes the world's largest earthworm, the Giant Gippsland Earthworm. The Giant Earthworm is found only in Gippsland, Victoria, on average they reach 80 cm in length and specimens up to 3.7 m in length have been found. There are many more families of aquatic oligochaetes than there are terrestrial families. Wolf spider Lycosa godeffroyi is common in many areas of Australia. Females from this family of spiders carry their egg-sac. Freshwater crustaceans include the large family Parastacidae, which incorporates 124 species of freshwater crayfish. Australian species include the world's smallest crayfish, Swamp Crayfish, which does not exceed 30 mm in length; and the world's largest crayfish, the Tasmanian Giant Freshwater Crayfish, measuring up to 76 cm long and weighing 4.5 kg. The genus Cherax includes the Common Yabby—the most widely distributed species—in addition to the farmed species Marron and Queensland Red Claw. Species from the genus Engaeus, commonly known as the land crayfish, are also found in Australia. Engaeus species are not entirely aquatic, because they spend most of their lives living in burrows. Australia has seven species of freshwater crab from the genus Austrothelphusa. The crabs live burrowed into the banks of waterways and can plug their burrows, surviving several years through drought. The freshwater mountain shrimp occur only in Tasmania; they are a unique group because they are extremely primitive, resembling species found in the fossil record from 200 MYA. Clownfish in their home, a Magnificent Sea Anemone on the Great Barrier Reef. A huge variety of marine invertebrate taxa are found in Australian waters, with the Great Barrier Reef being an obvious source of this diversity. Families include the Porifera or sea sponges, the Cnidaria (includes the jellyfish, corals and sea anemones, comb jellies), the Echinodermata (includes the sea urchins, starfish, brittle stars, sea cucumbers, the lamp shells) and the Mollusca (includes snails, slugs, limpets, squid, octopuses, cockles, oysters, clams, and chitons). Venomous invertebrates include the Box Jellyfish, the Blue-ringed Octopus and ten species of Cone Snail, which can cause respiratory failure and death in humans. The Crown-of-Thorns Starfish usually inhabits the Reef at low densities. However, under conditions that are not yet understood by science, they can reproduce to reach an unsustainable population density when coral is devoured at a rate faster than it can regenerate. This presents a serious reef management issue. Other problematic marine invertebrates include the native species Purple Sea-urchin and the White Urchin, which have been able to take over marine habitats and form urchin barrens due to the over harvesting of their natural predators. Introduced pests include the Asian Mussel, New Zealand Green-lipped Mussel, Black-striped Mussel and the Northern Pacific Seastar, all of which displace native shellfish. There are many unique marine crustaceans in Australian waters among the country's seven represented classes. The best-known class, to which all the edible species of crustacean belong, is Malacostraca. The warm waters of northern Australia are home to many species of Decapod crustaceans, including crabs, false crabs, hermit crabs, lobsters, shrimps, and prawns. The Peracarids including the amphipods and isopods are more diverse in the colder waters of southern Australia. Less-well-known marine groups include the classes Remipedia, Cephalocarida, Branchiopoda, Maxillopoda (which includes the barnacles, copepods and fish lice), and the Ostracoda. Notable species include the Tasmanian Giant Crab, the second largest crab species in the world, found in deep water, and weighing up to 13 kg and the Australian lobsters like the Western Rock Lobster, which are distinct from other lobster species as they do not have claws. Human impact and conservation Main article For at least 40,000 years, Australia's fauna played an integral role in the traditional lifestyles of Indigenous Australians, who exploited many species as a source of food and skins, and for sport and pest control. Vertebrates commonly harvested included macropods, possums, seals, fish and the Short-tailed Shearwater, most commonly know as the Muttonbird. Invertebrates used as food included insects like the Bogong moth and larvae collectively called witchetty grubs and molluscs. The use of fire-stick farming, in which large swathes of bushland were burnt to facilitate hunting, modified both flora and fauna — including large herbivores with a specialised diet, such as the flightless birds from the genus Genyornis.[13] The role of Indigenous people in the extinction of the Australian megafauna is uncertain. No archæological evidence has been found to support the hypothesis that intensive hunting caused the extinction of megafauna, so climate change in Pleistocene is considered a more likely explanation for the megafauna extinction.[12] The Grey Nurse Shark is critically endangered on the Australian east coast. The impact of Aborigines on native species populations is widely considered to be less significant than that of the European settlers,[14] whose impact on the landscape has been on a relatively large scale. Since European settlement, direct exploitation of native fauna, habitat destruction and the introduction of exotic predators and competitive herbivores has led to the extinction of some 27 mammal, 23 bird and 4 frog species. Much of Australia's fauna is protected by legislation; a notable exception is kangaroos, which are prolific and are regularly culled. The federal Environment Protection and Biodiversity Conservation Act 1999 was created to meet Australia's obligations as a signatory to the 1992 Convention on Biological Diversity. This act protects all native fauna and provides for the identification and protection of threatened species. In each state and territory, there is statutory listing of threatened species. At present, 380 animal species are classified as either endangered or threatened under the EPBC Act, and other species are protected under state and territory legislation.[15] More broadly, a complete cataloguing of all the species within Australia has been undertaken, a key step in the conservation of Australian fauna and biodiversity. In 1973, the federal government established the Australian Biological Resources Study (ARBS), which coordinates research in the taxonomy, identification, classification and distribution of flora and fauna. The ARBS maintains free online databases cataloguing much of the described Australian flora and fauna. Australia is a member of the International Whaling Commission and is strongly opposed to commercial whaling—all Cetacean species are protected in Australian waters. Australia is also a signatory to the CITES agreement and prohibits the export of endangered species. Protected areas have been created in every state and territory to protect and preserve the country's unique ecosystems. These protected areas include national parks and other reserves, as well as 64 wetlands registered under the Ramsar Convention and 16 World Heritage Sites. As of 2002, 10.8% (774,619.51 km²) of the total land area of Australia is within protected areas.[16] Protected marine zones have been created in many areas to preserve marine biodiversity; as of 2002, these areas cover about 7% (646,000 km²) of Australia's marine jurisdiction.[17] The Great Barrier Reef is managed by the Great Barrier Reef Marine Park Authority under specific federal and state legislation. Some of Australia's fisheries are already overexploited,[18] and quotas have been set for the sustainable harvest of many marine species. The State of the Environment Report, 2001, prepared by independent researchers for the federal government, concluded that the condition of the environment and environmental management in Australia had worsened since the previous report in 1996. Of particular relevance to wildlife conservation, the report indicated that many processes—such as salinity, changing hydrological conditions, land clearing, fragmentation of ecosystems, poor management of the coastal environment, and invasive species—pose major problems for protecting Australia's biodiversity.[19] See also Endangered Australian fauna Extinct Australian fauna Recently extinct Australian animals: from 1788 to present; Australian megafauna: from first human colonisation to 1788 List of monotremes and marsupials List of Australian bats List of Australian rodents List of Australian marine mammals List of Australian birds and the list of Australasian birds List of common Australian spiders Invasive species in Australia Notes 1. ^ Williams, J. et al. 2001.
