The pads of the feet are well developed and their coarse texture allows good traction on rock surfaces. In modern times, these populations have come to be viewed as exotic pests, with severe impacts on the indigenous flora and fauna. Attempts at reintroduction into the Grampians National Park during 2008-12 were not successful, largely due to fox predation. Before the breeding program, the last Southern Brush-tailed Rock-Wallaby was seen in the wild in the ACT in 1959. Currently, the primary threat to the population of the Brush-tailed rock-wallabies is modification of their natural habitat due to: invasion of non-native plants; exotic herbivore grazing; drought; disease outbreaks; fires; clearance of habitat; tourism; residential development. Due to an escape of a pair in 1916, a small breeding population of the brush-tailed rock-wallabies also exists in the Kalihi Valley on the island of Oahu in Hawaii. Herbert's rock-wallaby (P. herberti) overlaps in the northern range of this species, their coloration is greyer than the warm brown of this species and lighter at the darker features of the limbs; the tail of that species also lacks the blackish features and bushy end. Black colored bands run along the pale grey flanks of the wallaby. Brush-Tailed Rock-Wallaby on The IUCN Red List site -, https://en.wikipedia.org/wiki/Brush-tailed_rock-wallaby, http://www.iucnredlist.org/details/16746/0. The species favours north facing refuges, and while largely nocturnal in venturing out from shelter they will bask in winter sun for short periods. Australian Government: VULNERABLE Environment Protection and Biodiversity Conservation Act 1999 New South Wales: ENDANGERED Threatened Species Conservation Act 1995 Victoria: THREATENED Flora and Fauna Guarantee Act 1998 According to the IUCN Red List, the total population size of Brush-tailed rock-wallabies is estimated to be between 15,000 and 30,000 individuals, including 20,000 mature individuals. The paler under parts may feature a white blazon on the chest. In Victoria, the Brush-tailed Rock-wallaby now exists in only two small and isolated locations. [4] However, due to the large bushfire event currently occurring in South-East Australia around 70% of all the wallaby's habitat has been lost as of January 2020. They live in colonies, and although they rarely make a sound, scientists believe that members communicate using a complex array of behaviours and chemical signals. They also spend time sunbathing on steep rocks. The Mount Rothwell Research and Conservation Reserve started with 20 southern brush-tailed rock wallabies in 2016. In addition, the long and bushy tail of the animal helps the wallaby balance, when it leaps over boulders. The Brush-tailed Rock-wallaby has long, dense fur with a coarse texture. This agile species lives in rugged, rocky areas and can bound great distances, up and across rocky terrain. Both males and females fiercely defend their home ranges as well as their den sites. A small and muscular macropod, the Brush-tailed rock-wallaby is known for its long and bushy tail, white cheek stripe and black stripe from its forehead to the back of its head. The fur on its chest and belly are paler, and some individuals have a white blaze on their chest. The species was first described by John Edward Grey: in 1927, he gave the wallaby its name based on a drawing by Lewin from what was then called New Holland. The weight range is from 5 to 8 kilograms. [3] The taxon has been named for a species complex, the Petrogale penicillata-lateralis group, the systematics of which continued to be resolved, A species of Petrogale, the rock wallabies, with a dense and shaggy pelage that is rufous or grey brown. In 2003 some Kawau brush-tails were relocated to the Waterfall Springs Conservation Park north of Sydney, New South Wales, for captive breeding purposes.

The Brush-tailed Rock-wallaby has a characteristic, long and bushy, dark rufous-brown tail that is bushier towards its tip. In course of time, Brush-tailed rock-wallabies have adapted to their rugged habitat, becoming able to move swiftly through rocky terrains of their range. The general dorsal colour from mid back to rump is grey-brown. 1. To survive on the rocky areas that they live in they have strong back legs and a long tail to balance on the steep slopes. Brush-tailed rock-wallabies typically rest in vegetation, caves or overhang. Their great agility while hopping and climbing provides opportunities at ledges, cliff-faces, overhangs, caves and crevices. Brush-tailed Rock-wallabies (BTRW) naturally live in areas with bare rock in rocky hills and gorges, and these habitats are mostly found in the uplands of the Great Dividing Range. The brush-tailed rock-wallaby or small-eared rock-wallaby (Petrogale penicillata) is a kind of wallaby, one of several rock-wallabies in the genus Petrogale. In 2000 they were declared nationally vulnerable to extinction. In addition, staring intensely is another form of communication in this species. Individual foraging territories for the species are around 15 hectares, perhaps more for males.[6]. The black-footed and flanked species Petrogale lateralis, which occurs in central Australia, is distinguished by its larger size and the shorter and darker fur of the tail and hind parts. They are classified as Vulnerable (VU), and numbers of their population are decreasing today. The tail is 500 to 700 millimetres long, exceeding the 510 to 580 mm combined length of the head and body. Gestation period lasts for about 30 days, yielding a single joey, which is born with undeveloped eyes, hind limbs and tail. The end third of Brush-tailed rock-wallaby’s tail is bushy, and typically brown to black, giving the animal its common name. This can certainly be shortened as they are subject to predation by eagles.

One of the largest rock-wallabies, this animal, however, is not very big as compared to other wallaby species. The brush-tailed rock wallabies’ most notable feature, as their name implies, is the distinctively bushy tail. The females of the colony cohere as maternal groups, with male progeny moving to other groups within the colony or migrating to another location. Then, for the next 7 - 20 days, the baby leaves the pouch multiple times, returning every time. They have also been observed nose jabbing: this is when a wallaby thrusts its nose towards another individual. Habitat & Distribution. At Jenolan Caves, Sid Bellingham, a local hunting guide, noted in 1899 that the Brush-tailed Rock-wallaby was “at one time plentiful”, “the Grand Arch and other outside caves were simply the camping place of rock wallabies” and “afforded good lively shooting”, but the species was declining by the late 1800s. The shelter on the left, originally used by ferry passengers, is now frequented by rock wallabies.They are accustomed to being fed in this area, with the most wallabies being found after 4.30 p.m. Once a common marsupial, southern brush-tail rock wallabies were almost completely wiped out by the fur trade in the 19th and 20th centuries, and by 1990, the animal was on the brick on extinction. Adult brush-tailed rock-wallabies weigh between five and eight kilograms. > Saving Jenolan’s Brush-Tailed Rock Wallabies from the Brink of Extinction Jenolan’s Brush-Tailed Rock Wallabies Win the Struggle to Survive May 3, 2020 Procreation is founded on breeding females utilising a single male for insemination, with births that occur throughout the year. The soles of their feet also help them to get extra grip on the rocks.

[5], The coloration of the species in the northern parts of population is paler and fur is shorter in length. Between 1967 and 1975, 210 rock-wallabies were captured on Kawau Island and returned to Australia, along with thousands of other wallabies. And finally, at 9 months old, the young wallaby is completely weaned. Where do they live? Very dark fur covers the lower parts of the limbs, paws and feet, and on the sides beneath the fore limbs of the animal; a whitish stripe may appear along the side of the body.
