Wombat

Wombats are short-legged, muscular quadrupedal marsupials of the family Vombatidae that are native to Australia. Living species are about 1 m (40 in) in length with small, stubby tails and weigh between 20 and 35 kg (44 and 77 lb). They are adaptable and habitat tolerant, and are found in forested, mountainous, and heathland areas of southern and eastern Australia, including Tasmania, as well as an isolated patch of about 300 ha (740 acres) in Epping Forest National Park[2] in central Queensland.

Genera and species

Etymology

The name "wombat" comes from the now nearly extinct Dharug language spoken by the aboriginal Dharug people, who originally inhabited the Sydney area.[3] 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 [51 cm] 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."[4] Wombats were often called badgers by early settlers because of their size and habits. Because of this, localities such as Badger Creek, Victoria, and Badger Corner, Tasmania, were named after the wombat.[5] The spelling went through many variants over the years, including "wambat", "whombat", "womat", "wombach", and "womback", possibly reflecting dialectal differences in the Darug language.[3]

Evolution and taxonomy

Though genetic studies of the Vombatidae have been undertaken, evolution of the family is not well understood. Wombats are estimated to have diverged from other Australian marsupials relatively early, as long as 40 million years ago, while some estimates place divergence at around 25 million years.[6]: 10–  Some prehistoric wombat genera greatly exceeded modern wombats in size. The largest known wombat, Phascolonus, which went extinct approximately 40,000 years ago,[7] is estimated to have had a body mass of up to 360 kilograms (790 lb).[8]

Characteristics

Wombats dig extensive burrow systems with their rodent-like front teeth and powerful claws. One distinctive adaptation of wombats is their backward pouch. The advantage of a backward-facing pouch is that when digging, the wombat does not gather soil in its pouch over its young. Although mainly crepuscular and nocturnal, wombats may 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.

Wombats leave distinctive cubic feces.[9] As wombats arrange these feces to mark territories and attract mates, it is believed that the cubic shape makes them more stackable and less likely to roll, which gives this shape a biological advantage. The method by which the wombat produces them is not well understood, but it is believed that the wombat intestine stretches preferentially at the walls, with two flexible and two stiff areas around its intestines.[10] The adult wombat produces between 80 and 100, 2 cm (0.8 in) pieces of feces in a single night, and four to eight pieces each bowel movement.[11][12] In 2019 the production of cube-shaped wombat feces was the subject of the Ig Nobel Prize for Physics, won by Patricia Yang and David Hu.[13]

All wombat teeth lack roots and are ever-growing, like the incisors of rodents.[14] Wombats are herbivores; their diets consist mostly of grasses, sedges, herbs, bark, and roots. Their incisor teeth somewhat resemble those of 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 1.0.1.41.0.1.4 × 2 = 24.

Wombats' fur can vary from a sandy colour to brown, or from grey to black. All three known extant species average around 1 metre (3 ft 3 in) in length and weigh between 20 and 35 kg (44 and 77 lb).

Female wombats give birth to a single young after a gestation period of roughly 20–30 days, which varies between species.[15][16] All species 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.[17]

A group of wombats is known as a wisdom,[18][19] a mob, or a colony.[20]

Wombats typically live up to 15 years in the wild, but can live past 20 and even 30 years in captivity.[21][22] The longest-lived captive wombat lived to 34 years of age.[22]

In 2020, biologists discovered that wombats, like many other Australian marsupials, display bio-fluorescence under ultraviolet light.[23][24][25]

Ecology and behaviour

Wombats have an extraordinarily slow metabolism, taking around 8 to 14 days to complete digestion, which aids their survival in arid conditions.[17] They generally move slowly.[26] When threatened, however, they can reach up to 40 km/h (25 mph) and maintain that speed for 150 metres (490 ft).[27] 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).[17]

Dingos and Tasmanian devils prey on wombats. Extinct predators were likely to have included Thylacoleo and possibly the thylacine (Tasmanian tiger). Their primary defence is their 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.[28] According to an urban legend, wombats sometimes 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. However, there is no evidence to support this.[29]

Wombats are generally quiet animals. Bare-nosed wombats can make a number of different sounds, more than the hairy-nosed wombats. Wombats tend to be more vocal during mating season. When angered, they can make hissing sounds. Their call sounds somewhat like a pig's squeal. They can also make grunting noises, a low growl, a hoarse cough, and a clicking noise.[30]

Species

The three extant species of wombat[1] are all endemic to Australia and a few offshore islands. They are protected under Australian law.[27]

Human relations

History

Depictions of the animals in rock art are exceptionally rare, though examples estimated to be up to 4,000 years old have been discovered in Wollemi National Park.[32] The wombat is depicted in aboriginal Dreamtime as an animal of little worth. The mainland stories tell of the wombat as originating from a person named Warreen whose head had been flattened by a stone and tail amputated as punishment for selfishness. In contrast, the Tasmanian aboriginal story first recorded in 1830 tells of the wombat (known as the drogedy or publedina) the great spirit Moihernee had asked hunters to leave alone. In both cases, the wombat is regarded as having been banished to its burrowing habitat.[33] Estimates of wombat distribution prior to European settlement are that numbers of all three surviving species were prolific and that they covered a range more than ten times greater than that of today.[6]

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.[34] A live animal was taken back to Port Jackson.[34] Matthew Flinders, who was 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[35] to verify that it was a new species. The island was named Clarke Island after William Clark.[36][37]

Wombats were classified as vermin in 1906, and a bounty was introduced in 1925.[6]: 103  This and the removal of a substantial amount of habitat have greatly reduced their numbers and range.

Attacks on humans

Humans can receive puncture wounds from wombat claws, as well as bites. Startled wombats can also charge humans and bowl them over,[38] 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 woollen socks.[39] 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),[40] causing a number of cuts and bite marks requiring hospital treatment. He resorted to killing it with an axe.[41]

Cultural significance

Common wombats are considered by some farmers as a nuisance due primarily to their burrowing behaviour. "Fatso the Fat-Arsed Wombat" was the tongue-in-cheek "unofficial" mascot of the 2000 Sydney Olympics. Since 2005, an unofficial holiday called Wombat Day has been observed on 22 October.[42]

Wombat meat has been a source of bush food from the arrival of aboriginal Australians to the arrival of Europeans. Due to the protection of the species, wombat meat as food is no longer part of mainstream Australian cuisine, but wombat stew was once one of the few truly Australian dishes.[43] In the 20th century, the more easily found rabbit meat was more commonly used. (Rabbits are now considered an invasive pest in Australia.) The name of the dish is also used by a popular children's book and musical.[44]

Wombats have featured in Australian postage stamps and coins. The hairy-nosed wombats have featured mainly to highlight their elevated conservation status. The northern hairy-nosed wombat featured on an Australian 1974 20-cent stamp and also an Australian 1981 five-cent stamp. The common wombat has appeared on a 1987 37-cent stamp and an Australian 1996 95-cent stamp. The 2006 Australian Bush Babies stamp series features an AU$1.75-stamp of a baby common wombat, and the 2010 Rescue to Release series features a 60-cent stamp of a common wombat being treated by a veterinarian. Wombats are rarely seen on circulated Australian coins, an exception is a 50-cent coin which also shows a koala and lorikeet. The common wombat appeared on a 2005 commemorative $1 coin and the northern hairy-nosed wombat on a 1998 Australia Silver Proof $10 coin.[45]

Many places in Australia have been named after the wombat, including a large number of places where they are now locally extinct in the wild. References to the locally extinct common wombat can be found in parts of the Central Highlands of Victoria, for example the Wombat State Forest and Wombat Hill in Daylesford. Other significant places named after the wombat includes the town of Wombat, New South Wales. Numerous less significant Australian places, including hotels, are named after the animals. Prominent sculptures of wombats include in South Australia: "The Big Wombat" at Scotdesco Aboriginal Community (Tjilkaba) and Wudinna visitor information centre, Adelaide Zoo and Norwood; New South Wales: Wombat, New South Wales; Victoria: Daylesford, Trentham, Victoria and Kinglake; Tasmania: Steppes State Reserve.

Wombats have also been a feature of Australian television. While wombats are not generally kept as pets, a notable depiction of a common wombat as a pet is Fatso from the Australian television show A Country Practice. The Brisbane television show Wombat was also named for the animals.

Australian literature contains many references to the wombat. Examples are Mr. Walter Wombat from the adventures of Blinky Bill and one of the main antagonists in The Magic Pudding by Norman Lindsay.

Conservation

All species of wombats are protected in every Australian state.[46]

The northern hairy-nosed wombat is an endangered species.[47] 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.[47][48]

The only known wild populations of this species exist in two locations in Queensland, the Epping Forest National Park, and a smaller colony being established by translocating wombats to the Richard Underwood Nature Refuge at Yarran Downs.[47] This second colony is being created through the Xstrata reintroduction project, which is being funded by Xstrata, a Swiss global mining company.[49]

The wombat population in the Epping Forest National Park has been increasing since a predator-proof fence was erected in the park.[47] According to the latest census, taken in 2013, the park is home to 196 of these endangered wombats, with numbers at the two locations expected to have increased to 230 by late 2015.[47]

Despite its name, the common wombat is no longer common, and it has been officially a protected animal in New South Wales since 1970.[50] However, in eastern Victoria, they are not protected, and they are considered by some to be pests, especially due to the damage they cause to rabbit-proof fences.[47][51] Opportunistic research studies have been conducted on the immune system of common wombats, which could be used as a tool for future conservation efforts.[52]

WomSAT, a citizen science project, was established in 2016 to record sightings of wombats across the country.[53][54] The website and mobile phone app can be used to log sightings of live or deceased wombats and wombat burrows. Since its establishment the project has recorded over 23,000 sightings across New South Wales, Victoria, Tasmania and South Australia.[55][56] More recently, the citizen science project has published findings on wombat roadkill[57] and sarcoptic mange incidence[58] across Australia.

understood Wombats are estimated to have diverged from other Australian marsupials relatively early as long as 40 million years ago while some estimates place divergence at around 25 million years 6 10 Some prehistoric wombat genera greatly exceeded modern wombats in size The largest known wombat Phascolonus which went extinct approximately 40 000 years ago 7 is estimated to have had a body mass of up to 360 kilograms 790 lb 8 Characteristics nbsp Wombat in Narawntapu National Park TasmaniaWombats dig extensive burrow systems with their rodent like front teeth and powerful claws One distinctive adaptation of wombats is their backward pouch The advantage of a backward facing pouch is that when digging the wombat does not gather soil in its pouch over its young Although mainly crepuscular and nocturnal wombats may 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 Wombats leave distinctive cubic feces 9 As wombats arrange these feces to mark territories and attract mates it is believed that the cubic shape makes them more stackable and less likely to roll which gives this shape a biological advantage The method by which the wombat produces them is not well understood but it is believed that the wombat intestine stretches preferentially at the walls with two flexible and two stiff areas around its intestines 10 The adult wombat produces between 80 and 100 2 cm 0 8 in pieces of feces in a single night and four to eight pieces each bowel movement 11 12 In 2019 the production of cube shaped wombat feces was the subject of the Ig Nobel Prize for Physics won by Patricia Yang and David Hu 13 nbsp Wombat cubic scat found near Cradle Mountain in TasmaniaAll wombat teeth lack roots and are ever growing like the incisors of rodents 14 Wombats are herbivores their diets consist mostly of grasses sedges herbs bark and roots Their incisor teeth somewhat resemble those of 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 1 0 1 4 1 0 1 4 2 24 Wombats fur can vary from a sandy colour to brown or from grey to black All three known extant species average around 1 metre 3 ft 3 in in length and weigh between 20 and 35 kg 44 and 77 lb Female wombats give birth to a single young after a gestation period of roughly 20 30 days which varies between species 15 16 All species 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 17 A group of wombats is known as a wisdom 18 19 a mob or a colony 20 Wombats typically live up to 15 years in the wild but can live past 20 and even 30 years in captivity 21 22 The longest lived captive wombat lived to 34 years of age 22 In 2020 biologists discovered that wombats like many other Australian marsupials display bio fluorescence under ultraviolet light 23 24 25 nbsp Dentition as illustrated in Knight s Sketches in Natural History nbsp Wombat skeleton nbsp Female reproductive tractEcology and behaviour nbsp Wombat burrow and scat Narawntapu National Park TasmaniaWombats have an extraordinarily slow metabolism taking around 8 to 14 days to complete digestion which aids their survival in arid conditions 17 They generally move slowly 26 When threatened however they can reach up to 40 km h 25 mph and maintain that speed for 150 metres 490 ft 27 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 17 Dingos and Tasmanian devils prey on wombats Extinct predators were likely to have included Thylacoleo and possibly the thylacine Tasmanian tiger Their primary defence is their 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 28 According to an urban legend wombats sometimes 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 However there is no evidence to support this 29 Wombats are generally quiet animals Bare nosed wombats can make a number of different sounds more than the hairy nosed wombats Wombats tend to be more vocal during mating season When angered they can make hissing sounds Their call sounds somewhat like a pig s squeal They can also make grunting noises a low growl a hoarse cough and a clicking noise 30 SpeciesThe three extant species of wombat 1 are all endemic to Australia and a few offshore islands They are protected under Australian law 27 Common wombat Vombatus ursinus Northern hairy nosed wombat or yaminon Lasiorhinus krefftii 31 Southern hairy nosed wombat Lasiorhinus latifrons Human relationsHistory Depictions of the animals in rock art are exceptionally rare though examples estimated to be up to 4 000 years old have been discovered in Wollemi National Park 32 The wombat is depicted in aboriginal Dreamtime as an animal of little worth The mainland stories tell of the wombat as originating from a person named Warreen whose head had been flattened by a stone and tail amputated as punishment for selfishness In contrast the Tasmanian aboriginal story first recorded in 1830 tells of the wombat known as the drogedy or publedina the great spirit Moihernee had asked hunters to leave alone In both cases the wombat is regarded as having been banished to its burrowing habitat 33 Estimates of wombat distribution prior to European settlement are that numbers of all three surviving species were prolific and that they covered a range more than ten times greater than that of today 6 nbsp Common wombat and joey eating from a bowl at a zooAfter the ship Sydney Cove ran aground on Clarke Island in February 1797 the crew of the salvage ship Francis discovered wombats on the island 34 A live animal was taken back to Port Jackson 34 Matthew Flinders who was 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 35 to verify that it was a new species The island was named Clarke Island after William Clark 36 37 Wombats were classified as vermin in 1906 and a bounty was introduced in 1925 6 103 This and the removal of a substantial amount of habitat have greatly reduced their numbers and range Attacks on humans Humans can receive puncture wounds from wombat claws as well as bites Startled wombats can also charge humans and bowl them over 38 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 woollen socks 39 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 40 causing a number of cuts and bite marks requiring hospital treatment He resorted to killing it with an axe 41 Cultural significance nbsp Side view of Fatso the Fat Arsed Wombat an unofficial mascot for the 2000 Summer

April 2002Common wombats are considered by some farmers as a nuisance due primarily to their burrowing behaviour Fatso the Fat Arsed Wombat was the tongue in cheek unofficial mascot of the 2000 Sydney Olympics Since 2005 an unofficial holiday called Wombat Day has been observed on 22 October 42 Wombat meat has been a source of bush food from the arrival of aboriginal Australians to the arrival of Europeans Due to the protection of the species wombat meat as food is no longer part of mainstream Australian cuisine but wombat stew was once one of the few truly Australian dishes 43 In the 20th century the more easily found rabbit meat was more commonly used Rabbits are now considered an invasive pest in Australia The name of the dish is also used by a popular children s book and musical 44 Wombats have featured in Australian postage stamps and coins The hairy nosed wombats have featured mainly to highlight their elevated conservation status The northern hairy nosed wombat featured on an Australian 1974 20 cent stamp and also an Australian 1981 five cent stamp The common wombat has appeared on a 1987 37 cent stamp and an Australian 1996 95 cent stamp The 2006 Australian Bush Babies stamp series features an AU 1 75 stamp of a baby common wombat and the 2010 Rescue to Release series features a 60 cent stamp of a common wombat being treated by a veterinarian Wombats are rarely seen on circulated Australian coins an exception is a 50 cent coin which also shows a koala and lorikeet The common wombat appeared on a 2005 commemorative 1 coin and the northern hairy nosed wombat on a 1998 Australia Silver Proof 10 coin 45 Many places in Australia have been named after the wombat including a large number of places where they are now locally extinct in the wild References to the locally extinct common wombat can be found in parts of the Central Highlands of Victoria for example the Wombat State Forest and Wombat Hill in Daylesford Other significant places named after the wombat includes the town of Wombat New South Wales Numerous less significant Australian places including hotels are named after the animals Prominent sculptures of wombats include in South Australia The Big Wombat at Scotdesco Aboriginal Community Tjilkaba and Wudinna visitor information centre Adelaide Zoo and Norwood New South Wales Wombat New South Wales Victoria Daylesford Trentham Victoria and Kinglake Tasmania Steppes State Reserve Wombats have also been a feature of Australian television While wombats are not generally kept as pets a notable depiction of a common wombat as a pet is Fatso from the Australian television show A Country Practice The Brisbane television show Wombat was also named for the animals Australian literature contains many references to the wombat Examples are Mr Walter Wombat from the adventures of Blinky Bill and one of the main antagonists in The Magic Pudding by Norman Lindsay Conservation All species of wombats are protected in every Australian state 46 The northern hairy nosed wombat is an endangered species 47 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 47 48 The only known wild populations of this species exist in two locations in Queensland the Epping Forest National Park and a smaller colony being established by translocating wombats to the Richard Underwood Nature Refuge at Yarran Downs 47 This second colony is being created through the Xstrata reintroduction project which is being funded by Xstrata a Swiss global mining company 49 The wombat population in the Epping Forest National Park has been increasing since a predator proof fence was erected in the park 47 According to the latest census taken in 2013 the park is home to 196 of these endangered wombats with numbers at the two locations expected to have increased to 230 by late 2015 47 Despite its name the common wombat is no longer common and it has been officially a protected animal in New South Wales since 1970 50 However in eastern Victoria they are not protected and they are considered by some to be pests especially due to the damage they cause to rabbit proof fences 47 51 Opportunistic research studies have been conducted on the immune system of common wombats which could be used as a tool for future conservation efforts 52 WomSAT a citizen science project was established in 2016 to record sightings of wombats across the country 53 54 The website and mobile phone app can be used to log sightings of live or deceased wombats and wombat burrows Since its establishment the project has recorded over 23 000 sightings across New South Wales Victoria Tasmania and South Australia 55 56 More recently the citizen science project has published findings on wombat roadkill 57 and sarcoptic mange incidence 58 across Australia References a b Groves C P 2005 Order Diprotodontia In Wilson D E Reeder D M
