A community-based postal survey (questionnaire and map) was undertaken in the Eden region of south-eastern New South Wales in 1991–92 to help determine the local distribution of koalas and to obtain information on which to base a regional plan of management for koalas. The 1198 replies from the II 600 households in the region represented all parts of the area surveyed. The survey responses suggest that koalas are rare in the Eden region, and that the number of koalas has been constantly low for the last four decades. The records are scattered both chronologically and geographically. National Parks and Nature Reserves have never been the stronghold of local koala populations, and freehold land, particularly farmland, is not a major reservoir of koalas. Most koalas reported were in, or adjacent to, State Forests, particularly Murrah–Berrnagui and Tantawangalo–Glenbog–Yurammie. These areas appear to contain the core of the surviving koala population of the region. An assessment of the vegetation where koalas were sighted indicated that dry forest is the preferred habitat. The once abundant and widespread local koala population of late last century has been reduced by habitat loss and fragmentation to a few small, isolated populations. This regional survey, which was undertaken by use of a carefully constructed questionnaire, revealed an invaluable source of records and contributed 70% of the records in the database used for this study. This study also laid a basis for assessing koala management options in south-eastern New South Wales.

A regional survey of the forests in north-eastern New South Wales recorded eight species of nocturnal forest birds and nine species of arboreal marsupials from 291 sites. Three major environmental gradients accounting for the distribution of these species in north-eastern New South Wales were identified: elevation, forest type (wet forest types having a dense mesic understorey or dry forest types having an open or sparse understorey), and logging intensity. Characteristic assemblages of species were associated with each end of these three gradients. A core group of species occurred across a wide range of environmental conditions, including logged and unlogged forest. Most species occurred with similar frequency in logged and unlogged forest. Implications for forest management are discussed.

Habitat loss and fragmentation are key threats to local koala (Phascolarctos cinereus) populations. Broad-scale management is suboptimal for koalas because distribution models are not easily generalised across regions. Therefore, it is imperative that data relevant to local management bodies are available. Genetic data provides important information on gene flow and potential habitat barriers, including anthropogenic disturbances. Little genetic data are available for nationally significant koala populations in north-eastern New South Wales, despite reported declines due to urbanisation and habitat loss. In this study, we develop 14 novel microsatellite loci to investigate koala populations in north-eastern New South Wales (Port Macquarie, Coffs Harbour, Tyagarah, Ballina) and south-eastern Queensland (Coomera). All locations were significantly differentiated (FST = 0.096–0.213; FʹST = 0.282–0.582), and this pattern was not consistent with isolation by distance (R2 = 0.228, P = 0.058). Population assignment clustered the more northern populations (Ballina, Tyagarah and Coomera), suggesting contemporary gene flow among these sites. For all locations, low molecular variation among (16%) rather than within (84%) sites suggests historical connectivity. These results suggest that koala populations in north-eastern New South Wales and south-eastern Queensland are experiencing contemporary impediments to gene flow, and highlight the importance of maintaining habitat connectivity across this region.

The eastern pygmy possum (Cercartetus nanus) has a wide distribution in New South Wales (NSW), but is infrequently detected in fauna surveys. We collated available information on the distribution, habitat and detection rates for C. nanus in NSW from results of published and unpublished fauna surveys. These data, and those from the National Parks and Wildlife Service and Australian Museum databases, suggest that C. nanus populations are concentrated in south-eastern NSW and are sparsely distributed throughout the rest of the state. Several records extend the distribution of this species further west than currently shown by published distribution maps. Records show differences in habitat types occupied by C. nanus between south-eastern and north-eastern NSW. In south-eastern NSW, C. nanus occupies a range of habitats including heath, woodland and open forest, at a range of altitudes. In north-eastern NSW, C. nanus appears to be associated mainly with rainforest at high altitudes. Of the range of techniques available, nest boxes and Elliott traps positioned against flowering Banksia species are most effective at capturing C. nanus. Given the large survey effort and the small number of surveys detecting >I0 C. nanus, it appears that this species is rare throughout most of NSW. We recommend that C. nanus be considered for listing as a vulnerable species in NSW.

A community-based survey was undertaken in the Lismore Local Government Area (LGA) of north-eastern New South Wales to provide a basis for the development of a Shire-wide koala management plan. A questionnaire and maps were distributed to identify community attitudes towards P. cinereus conservation and management, as well as to document locations of sightings. There were 1121 surveys returned from 23,751 distributed (4.7% returned) across 18,000 ratepayers (6.2% response). Respondents indicated the frequency with which P. cinereus were seen in different suburbs, whether they had young or were sick, and provided 840 map-based records. Ten percent of respondents saw P. cinereus on at least a weekly basis, highlighting the importance of this LGA for the conservation of this species. More than 80% of respondents considered that roving dogs, land clearing, road traffic and housing development were serious threats to long-term P. cinereus survival. More than 90% of respondents supported restrictions on dogs, tree-planting programs, as well as planning activities to protect P. cinereus habitat while 85% approved of protection zones to control development within P. cinereus habitat. These results if representative of the entire community suggest strong support for the development of conservation options for P. cinereus. The study also confirms the usefulness of conducting such community-wide surveys for conspicuous threatened species.

The distribution of Ornithorhynchus anatinus in the Eden region of south-east New South Wales is defined based on information from two community-based surveys. In 1986-87 a state-wide questionnaire survey was distributed to field staff from various government departments. A search for historical reports was also carried out. Fifty-five reports of platypuses were obtained from the Eden region, including 30 sightings on agricultural land. The second approach was through a joint National Parks and Wildlife Service and State Forests householder postal survey in 1991. The survey returns yielded 273 locations of O. anatinus of which 76% were on freehold rural land, 19% were in State Forests and 5% were in National Parks or Nature Reserves. Records from both surveys, spread from 1930 to the early 1990s, were from all parts of the region. The surveys showed that platypuses have been widespread in the region, but their now fragmented distribution indicates a reduction in the regional population of the species. Management of waterways and catchments are crucial to its long-term survival. The public awareness of the platypus shown by the number of questionnaire returns, is an encouraging sign that local plans to conserve or restore its habitat are likely to be well received if produced through the cooperative approach initiated by community-based surveys.

We examined the distribution and abundance of ground-dwelling mammals in the major eucalypt communities within 500 000 ha of eucalypt forest in south-eastern New South Wales. Data for 22 species of mammal are presented from 13 areas comprising 42 eucalypt communities. Two features were the abundance and widespread distribution of the introduced red fox and cat, and the absence of small wallabies (potoroo size) and low abundance of other medium-sized native mammals such as bandicoots. Six mammal species occurred in all areas and in most eucalypt communities. Although there were differences in the distribution and abundance of species between areas there was no significant difference between areas in the number of native and introduced species. Some mammal species were absent from some eucalypt communities, but no eucalypt community was devoid of ground-dwelling mammals and each had native and introduced species present. The E. fastigata group had the highest number of species (14) and one community (E. fastigata-E. cypellocarpa) contained the highest number of native (9) and introduced (4) species. The E. maculata group contained the lowest number of native species with eastern grey kangaroos absent and common wombats present in one community only. The results of this study suggest that management options for arboreal mammals may not apply to the ground-dwelling mammals. The ground-dwelling mammals present today in south-eastern New South Wales appear to be remnants of a more diverse fauna left after clearing, forestry activities and predation by introduced species. Some species are in urgent need of protection and management if they are to persist.

Native forest at Durras in south-eastern New South Wales and Jarrahdale in south-western Western Australia was examined for the presence of Phytophthora cinnamomi by two sampling and isolation techniques. With the lupin seeding baiting technique, randomly selected samples of soil and fine roots collected from the New South Wales site yielded P. cinnamomi when baited, while similar baiting of comparable samples from Western Australia failed. Direct plating of samples of upper roots and root collars of recently dead Banksia grandis from Western Australian sites yielded P. cinnamomi, while this organism was not isolated from comparable samples of chlorotic Macrozamia communis collected at the New South Wales site. The results suggest that the form of occurrence of P. cinnamomi and its association with disease in Australia vary in different situations. Viewing each situation independently might ensure the adoption of control/prevention strategies appropriate to all.
