There are no published estimates of mainland Quokka numbers, but the total adult population in the Northern and Central Jarrah Forest may be as few as 150 (Hayward et al. kidcyber cannot be held responsible for inappropriate sites Note: all kidcyber topics are regularly checked, updated and added to, so keep checking out this website. For example, Fox baiting is in place for most of the known populations on the Darling Scarp, and at Two Peoples Bay NP and Stirling Range NP. Journal of Hygiene. 2005a). 2007 cited in DEC 2013).

The Quokka was first observed by a European in 1658 when the Dutchman, Volkersen, wrote that it resembled an Asian civet cat, but with brown hair. Quokkas look like small kangaroos, they have developed hind legs, round ears, a short broad head. Bureau of Meteorology (2007). In Bullich forest, the understorey includes Acacia linearifolia, Boronia molloyiae and Hypocalymna cordifolium (Hayward 2002). 2005a). Image credit: gadigal yilimung (shield) made by Uncle Charles Chicka Madden. The other sub-populations occur in State Forest, which is not managed for conservation but is baited for foxes (DEC 2007). Individuals and organisations should consider all the They were once found all over southwestern Australia, but are now rarely seen on the mainland. Declaration under s178, s181, and s183 of the Environment Protection and Biodiversity Conservation Act 1999 - List of threatened species, List of threatened ecological communities and List of threatening processes. Storr, G.M., J.W. (1998). Life cycle of mongoose. The environment of the Quokka (Setonix brachyurus) in the Darling Range, Western Australia. Female Quokkas give birth to a single young about a month after mating. 2005a). Habitat, movements, breeding, and growth. [18] Despite the relative lack of fresh water on Rottnest Island, quokkas do have high water requirements, which they satisfy mostly through eating vegetation. 3:44-55. 66:20-24. Available from: http://www.comlaw.gov.au/Details/F2005B02653. Some species information is withheld in line with sensitive species polices. Sinclair, E.A. Department of Conservation and Land Management, unpublished report. Low-intensity control burns generally burn the swamp edges without penetrating the swamp. (1965). [38], Rottnest Island Regulations 1988 (WA), rr 40 & 73; sched. Australian Journal of Zoology. Identifying the presence of Quokkas (Setonix brachyurus) and other macropods using cytochrome b analysis from faeces. [21], An estimated 4,000 quokkas live on the mainland, with nearly all mainland populations being groups of fewer than 50, although one declining group of over 700 occurs in the southern forest between Nannup and Denmark. He named the Island 'Rotte nest' (meaning 'rat's nest') and the name of the Island was eventually adapted to 'Rottnest'. All of these attempts at introduction to this site failed (DEC 2007). Predation and habitat destruction through inappropriate fire regimes are thought to be the key drivers in the ongoing decline of the Quokka. ... Debra on The Life Cycle Of The Monarch Butterfly With Pictures & Facts; This is an indicative distribution map of the present distribution of the species based on best available knowledge. F2005B02653. Strahan R: Photographic Guide to the Mammals of Australia. Banks (2004). This is possibly due to the presence of fleas and ticks, resulting from the introduction of sheep, horses, rats, mice, cats and dogs, which spread disease such as toxoplasma, to which some native animals are susceptible (Abbott 2001). Their success on Bald Island is probably due to their finding suitable food sources and the lack of predators. The information contained in this It's coarse fur is a grizzled brown colour fading to buff underneath and their Anecdotal evidence that populations are affected by wildfire, but increasing in size in response to Fox control. Journal of comparative psychology. Quokka Setonix brachyurus Recovery Plan. Two factors in particular have probably contributed to declines: Fox predation and changed fire frequency. Across most of the region, the rainfall over recent decades has been significantly less than that recorded earlier in the twentieth century (Bureau of Meteorology 2007). Current Quokka capture methods rely on setting large numbers (up to 50) of large (0.5 x 0.5 x 0.9 m) wire cage traps (DEC 2007). Habitat clearing is attributable to agricultural developments (grazing and cropping), urbanisation, and logging. The young will remain in the pouch for about six months. Maxwell, S., A.A. Burbidge & K. Morris (1996). Fossil deposits suggest that the Quokka originally occupied an area of approximately 49 000 km² in the south-west WA. 1985).Quokkas are relatively difficult to trap and the repeated trapping required for mark and recapture studies is time-consuming (Alacs et al. [8] Its coarse fur is a grizzled brown colour, fading to buff underneath. There was another major population reduction in the period 1980–1992. 45(4):616-625.
