Bridled Nailtail Wallaby

Onychogalea fraenata

Status

Endangered (State & Commonwealth)

Problem

The removal of cover by sheep, cattle and rabbits, combined with droughts, has left Bridled Nailtails vulnerable to predation by feral cats and foxes. In Queensland the clearing of 5,700,000 hectares of brigalow and softwood scrubs has reduced the area of this wallaby's preferred habitat by around 95%.

Background Information

Bridled Nailtail Wallabies disappeared from the mallee scrubs of New South Wales and Victoria in the early 1900s. Today only one population of around 100 animals remains in remnant brigalow scrubs of Taunton National Park, central Queensland. This (2009) population represents a 30% reduction in the population recorded in the previous year.

Research

Research by the Queensland Department of Environment and Resource Management and the University of Queensland has shown that loss of native grasses and, in particular, encroachment of exotic buffel grass, as well as lack of preferred brigalow regrowth areas and drought within their limited habitat hamper their recovery. More recently, reduction in baiting for introduced predators has resulted in heavy losses attributed to dingoes, foxes and feral cats.

Solution

Control cats, foxes and dingoes. Maintain the existing populations at Taunton and translocation sites (Idalia NP which has 50 individuals and Avocet Nature Reserve, Carnarvon Range). Continue to establish new populations of Nailtails in other areas of suitable habitat.
