N2  - The aims of this study were to identify common ecological patterns among threatened fauna in New South Wales, and to identify priority areas for research and management by determining which regions and habitats contain high numbers of threatened fauna. Threatened and non-threatened fauna were taken from the listings of Lunney et al. (1996, 1997). Species were categorized into weight classes, diet groups, habitats and regions and by level of knowledge available about them. All regions and habitats of the State contain threatened species. The northeastern region of New South Wales contains the greatest number of threatened species but the western region has suffered the most extinctions, especially of mammals. Species that historically inhabited a greater number of regions are less likely to be currently threatened or to be extinct than those with restricted distributions, and large species are more likely to be threatened than smaller species. The best predictors of a threatened mammals species were seeds and vegetation in the diet, heavier body weight, and ground-dwelling, burrowing, and rock pile/cave-dwelling habits. The Critical Weight Range (35?5 500g), although strongly associated with extinction of non-volant mammals, was not the most important predictor. Lord Howe Island held the highest proportion of threatened and extinct birds. Factors showing the strongest associations for threatened birds were carnivory, large size, and distribution in the southeastern region. The most poorly-known region for birds was the north-east, and the least known habitat was shrubland (including mallee, heath and chenopod shrubland). The status of reptiles was poorly known in all regions, especially the western region. Frogs were also poorly known in all regions. Frogs were most at risk if they were large, inhabited closed forest or occurred in the central or northeastern region. The study further revealed little association between particular ecological attributes and conservation status. This indicates that there are complex and pervasive threats affecting the status of New South Wales fauna. Research and management priority status could be argued for all regions and most habitats in the State, but the western or northeastern regions may face the most problems depending on the criteria used (e.g., past extinctions, number vs proportion of threatened species). Further, the conservation status of birds, reptiles and frogs is in particular need of attention from researchers.
