|Genera and Species|
Wombats are short-legged, muscular quadrupedal marsupials, native to Australia, approximately 1 metre (40 in) in length, with short, stubby tails. They are adaptable in habitat tolerance, and are found in forested, mountainous, and heathland areas of south-eastern Australia, including Tasmania, as well as an isolated patch of about 300 hectares (740 acres) in Epping Forest National Park in central Queensland.
Wombats dig extensive burrow systems with rodent-like front teeth and powerful claws. One distinctive adaptation of wombats is their backwards pouch. The advantage of a backwards-facing pouch is that when digging, the wombat does not gather soil in its pouch over its young. Although mainly crepuscular and nocturnal, wombats also venture out to feed on cool or overcast days. They are not commonly seen, but leave ample evidence of their passage, treating fences as minor inconveniences to be gone through or under, and leaving distinctive cubic faeces.
Wombats are herbivores; their diets consist mostly of grasses, sedges, herbs, bark, and roots. Their incisor teeth somewhat resemble those of the placental rodents (rats, mice, etc.), being adapted for gnawing tough vegetation. Like many other herbivorous mammals, they have a large diastema between their incisors and the cheek teeth, which are relatively simple. The dental formula of wombats is 126.96.36.199 × 2 = 24
Wombats' fur can vary from a sandy colour to brown, or from grey to black. All three known extant species average around a metre in length and weigh between 20 and 35 kg (44 and 77 lb).
Female wombats give birth to a single young in the spring, after a gestation period, which like all marsupials can vary, in the case of the wombat: 20–21 days. They have well-developed pouches, which the young leave after about six to seven months. Wombats are weaned after 15 months, and are sexually mature at 18 months.
Ecology and behaviour 
Wombats have an extraordinarily slow metabolism, taking around eight to 14 days to complete digestion, which aids their survival in arid conditions. They generally move slowly. When threatened, however, they can reach up to 40 km/h (25 mph) and maintain that speed for up to 90 seconds. Wombats defend home territories centred on their burrows, and they react aggressively to intruders. The common wombat occupies a range of up to 23 ha (57 acres), while the hairy-nosed species have much smaller ranges, of no more than 4 ha (10 acres).
Dingos and Tasmanian devils prey on wombats. Their primary defence is its toughened rear hide, with most of the posterior made of cartilage. This, combined with its lack of a meaningful tail, makes it difficult for any predator that follows the wombat into its tunnel to bite and injure its target. When attacked, wombats dive into a nearby tunnel, using their rumps to block a pursuing attacker. A wombat may allow an intruder to force its head over the wombat's back, and then use its powerful legs to crush the skull of the predator against the roof of the tunnel, or drive it off with two-legged 'donkey' kicks.
Humans who accidentally find themselves in an fray with a wombat may find it best to scale a tree until the animal calms and leaves. Humans can receive puncture wounds from wombat claws, as well as bites. Startled wombats can also charge humans and bowl them over, with the attendant risks of broken bones from the fall. One naturalist, Harry Frauca, once received a bite 2 cm (0.8 in) deep into the flesh of his leg—through a rubber boot, trousers and thick woolen socks. A UK newspaper, The Independent, reported that on 6 April 2010 a 59-year-old man from rural Victoria state was mauled by a wombat (thought to have been angered by mange), causing a number of cuts and bite marks requiring hospital treatment. He resorted to killing it with an axe.

Discovery and naming 
After the ship Sydney Cove ran aground on Clarke Island in February 1797, the crew of the salvage ship, Francis discovered wombats on the island. A live animal was taken back to Port Jackson. Matthew Flinders travelling on board the Francis on its third and final salvage trip also decided to take a wombat specimen from the island to Port Jackson. Governor John Hunter later sent the animal's corpse to Joseph Banks at the Literary and Philosophical Society to verify it as a new species. The island was named Clarke Island after William Clark
The name "wombat" comes from the now nearly extinct Darug language spoken by the Aboriginal Darug people who originally inhabited the Sydney area. It was first recorded in January 1798 when John Price and James Wilson, a white man who had adopted Aboriginal ways, visited the area of what is now Bargo, New South Wales. Price wrote: "We saw several sorts of dung of different animals, one of which Wilson called a Whom-batt, which is an animal about 20 inches high, with short legs and a thick body with a large head, round ears, and very small eyes; is very fat, and has much the appearance of a badger." Wombats were often called badgers by early settlers because of their size and habit. Because of this, localities such as Badger Creek, Victoria, and Badger Corner, Tasmania, were named after the wombat. The spelling went through many variants over the years, including "wambat", "whombat", "womat", "wombach" and "womback", possibly reflecting dialectal differences in the Darug language.
The northern hairy-nosed wombat is an endangered species. The biggest threats the species faces are its small population size, predation by wild dogs, competition for food because of overgrazing by cattle and sheep, and disease. 
The only known wild populations of this species exist in two locations in Queensland, the Epping Forrest National Park, and a smaller colony being established by translocating wombats to the Richard Underwood Nature Refuge at Yarran Downs. This second colony is being created through the Xstrata reintroduction project which is being funded by Xstrata, a Swiss global mining company.
The wombat population in the Epping Forrest National Park has been increasing since a predator-proof fence was erected in the park. According to the latest census, taken in 2007, the park is home to 138 of these endangered wombats.
Wombat Day 
Since 2005, an unofficial holiday called Wombat Day has been observed on 22 October.
