The Woylie is a small marsupial with greyish-brown fur on the upperparts and flanks and pale grey fur on the underside. The tail is darkly coloured with a distinctive black brush at the end (hence the species’ common and scientific name). Adult males grow to 36 cm (head-body) and 1.8 kg. Females are slightly smaller than males. The Woylie population has declined from 225,000 to between 10,000 – 20,000 in the last 15 years. Picture: Australian Wildlife Conservancy

Brush tailed rabbit rat. Capture rates for brush-tailed rabbit rats have dropped by 60 per cent. University of Melbourne ecologist Hugh Davies said they had caught about 40 per cent less animals than in the 2002 surveys. “So for every ten animals caught last time, this time we only trapped six,” he said. “The result for brush-tailed rabbit-rats was worse. “We only caught about a third the number as last time, and only found them at half the number of sites.
