Surveys of Arboreal and Terrestrial Mammals in The Montane Forests of Queanbeyan, New South Wales.

Abstract

Surveys of arboreal and terrestrial mammals were conducted across four State Forests in south-east New South Wales encompassing 80 000 ha. Methods used included spotlighting, Elliott trapping, pitfall trapping, hair-tubing and predator scat analysis. The survey included a plot-based approach and the targeting of areas containing the potential habitat of endangered species. Seven species of arboreal marsupial were detected during spotlighting. The greater glider (Petauroides volans) was significantly more abundant in moist forest compared to dry forest. Its density in moist forest was twice as high in unlogged compared to logged forest and is equivalent to the highest recorded in any forest in NSW. Other arboreal species were less abundant. The yellow-bellied glider (Petaurus australis), which is Threatened in NSW, was detected at only two sites despite the occurrence of suitable habitat throughout the study area. Eight species of native terrestrial mammals were detected. The tiger quoll (Dasyurus maculatus), which is Threatened in NSW, appears to be more common in the southern part of the study area adjoining large areas of National Park, than in other State Forests of south-east NSW. Continued analysis of predator scats is required to determine whether several other species of Threatened terrestrial mammal occur in these forests.
