THREATENED SPECIES INFORMATION Brush-tailed Rock Wallaby Warrumbungles Endangered Population Petrogale penicillata (Gray, 1825) Other common name(s) None Conservation status 1999). In the remainder of Australia, the Brush-tailed Rock Wallabies in the Brush-tailed Rock Wallaby occurs in south-east Warrumbungle Ranges were thought to be Queensland and in an isolated population in extinct until their re-discovery in 1993 (Wong Victoria (Eldridge & Close 1995). 1999). The population in the Warrumbungle bitat Ranges is now listed as Endangered on The Warrumbungles Endangered Population Schedule 1, part 2 of the Threatened Species of the Brush-tailed Rock Wallaby inhabits Conservation Act 1995 (TSC Act). In the steep, rugged, rocky sites. Vegetation on these remainder of NSW, the Brush-tailed Rock rocky sites generally consists of low shrubs, Wallaby is listed as an Endangered Species on figs and grasses (Moss et al 1997). Adjacent Schedule 1 of the TSC Act. foraging habitat varies from Spinifex grassland to Acacia woodland with a grassy understorey Description (summarised from Eldridge & and Cyprus Pine and Ironbark woodland with Close 1995) a shrubby understorey (Moss et al 1997). Head and Body Length Elsewhere in NSW, the Brush-tailed Rock 529-586 (557)mm (males) Wallaby occurs in a variety of habitats, ranging 510-570 (536)mm (females) from rainforest to sclerophyll forest and open Tail Length woodland (Eldridge & Close 1995). 510-700 (611)mm (males) 500-630 (563)mm (females) Weight 5.5-10.9 (7.9)kg (males) 4.9-8.2 (6.3)kg (females) The Brush-tailed Rock Wallaby has brown fur above, merging into rufous on the rump and grey on the shoulders. The fur on the underside is pale to white. Distinguishing features are the prominent brush-tail, pale cheek stripe and black stripe from the forehead to back of head. The tail, feet and paws are dark brown to black. istribution The Endangered Population of the Brush-tailed Rock Wallaby occurs within and outside of Warrumbungle National Park, to the west of Coonabarabran. Elsewhere in NSW, this species has a fragmented distribution on the coast and ranges from the Queensland border to the south coast. It is very rare in the southern E Holland/NPWS and western parts of its distribution (Dovey et al. 1997) and to the west of the Great Dividing Range, only Brush-tailed Rock Wallaby the population in the Warrumbungles remains (Wong x $$$$$$$ r$$$$$$$$$$ $ r$$$$ $$ $$$$$$$$$r$$$$$$$$$$$$$$$$$$ $$$$ rr #Y $ r Lismore $$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$ #Y $ $ #Y Moree $$ Tibooburra $ $$ $$$$$$$ $$ #Y $ $ Grafton $$$ $ #Y $ $$$$$ $ Brourke r $r $r r $ rr $$$$$$$ $ #Y r$$$$ $$$$$$$$$ Tamwo$$$$$rth r $$ #Y $$$ $ Port Macquarie r #Y Broken Hill r #Y $$ Dubbo r $ $ $ $ $ $$ r $$$ $$$ rr $ $$$ $$$$$ #Y $$ $$$$$r$$$ Newcastle $ $$$ $$$$rrr $ r $$$$$$ $$ $ $ $ r $$ $ r rrrr $r #Y N $ Sydney #Y Griffith $ W E #Y Wollongong $ r$$$$ S $ $r$$rr $$rr #Y Wagga Wagga r $ The sightings represented on this m ap are #Y Bega only indicative.

Sunny, north- aggressively when in contact with each other facing sites are also preferred (Short 1982). (Jarman & Bayne 1997). Individual animals often use the same refuge over a period of time (Jarman & Bayne 1997). This small wallaby Ecology is particularly agile and is able to escape Brush-tailed Rock Wallabies occur in small predators on steep cliffs (Short 1982) and in groups or ‘colonies’ each usually separated by the lower branches of trees (Jarman & Bayne hundreds of metres (Jarman & Bayne, 1997). 1997). A total of seven colonies make up the Warrumbungles population, each colony Brush-tailed Rock Wallabies remain in the consisting of five to six individuals (NSW shelter and safety of refuges for much of the Scientific Committee). day, emerging to feed during the evening, usually within 200m of the refuge site (Jarman Each colony uses a number of different rocky & Bayne 1997). This species feeds outcrops or ‘refuges’ (Jarman & Bayne, 1997). predominantly on grasses and forbs and the Refuges are generally caves or crevices among foliage of shrubs and trees (Short, 1989). Seeds large boulders, but dense vegetation, in and fruits are eaten on a seasonal basis (Short, THREATENED SPECIES INFORMATION 1989).
