Habitat Fidelity

Little has been published about Sminthopsis murina, a small insectivorous marsupial encountered infrequently during trapping studies. Individuals favour vegetation associations found in recently burnt heathlands and forests; however, individuals rarely remain in such areas long enough for repeated capture. We report an unusual occurrence of habitat fidelity by a dense population of subadult S. murina in coastal wet heath, New South Wales, Australia. Individuals were captured repeatedly in the first 16 months following wildfire (30 subadults trapped 154 times: recapture rate = 80%). Densities peaked 10 months after fire at 3.75 individuals ha–1. More males than females were captured (23 males, 7 females). Habitat analyses revealed differential use of regenerating coastal wet heathland by S. murina. Significantly more captures were made in areas of high soil moisture in the first six months following fire. Captures then decreased in these areas but increased where soil moisture had been lower and where vegetation had been growing more slowly. Beyond the 1995/96 breeding season, regenerating vegetation became increasingly dense and less patchy and captures of S. murina ultimately declined to zero. This paper records a rare opportunity to examine habitat preferences of a single cohort of subadult S. murina. Habitat use may have been determined by the presence of a narrow range of vegetation structure.

Natural Range

Caulerpa filiformis is a green seaweed found in New South Wales (NSW, Australia), South Africa, Mozambique and Peru. It has been suggested that the abundance of the species has increased in NSW over recent decades. Extensive aerial and diver surveys identified a 500-km northerly extension to the range of C. filiformis in NSW (to 28°21′S) compared with previous records. The alga has a disjunct distribution with small isolated populations around rocky headlands in far northern NSW, but then no apparent populations for 350km southwards. The far northern populations could be the result of recent human-mediated transport (a species introduction), or were simply not detected previously. The increased distribution around the previous northerly limit is likely a natural range expansion. The distribution of C. filiformis in NSW and globally seems confined to a temperature range of ~16–23°C. We found no relationship between abundance of C. filiformis and human population or oceanic chlorophyll-a (a surrogate for nutrient availability). We demonstrate that C. filiformis is predominately subtidal, being found along sections of coastline where there is a mixture of rocky reefs and beaches. It is argued that sand movement may have facilitated increases in abundance of C. filiformis.

Seven species of possums and gliders were found during a survey in logged coastal forests near Bega, New South Wales. A study of the preferences for the various tree species showed that both commercial and non-commercial species must be retained to support the full range of possum and glider species. Spotlight searches were carried out in 6 adjacent felling areas each autumn from 1981 to 1983. Four species (Petaurus breviceps, P. australis, Petauroides volans and Pseudocheirus peregrinus) were seen frequently enough to determine their habitat preferences. There were significantly fewer possums and gliders in logged areas, with a greater effect on some species, e.g. P. volans, than others, e.g. P. breviceps. Fire rendered the logged areas even less habitable, and drought compounded the effects of logging and fire by further reducing numbers. Deep unlogged gullies were found to be crucial refuges from logging, fire and drought. The primary conclusions are that the current logging operation is causing a significant reduction in numbers, and that gullies need to be redefined to include all drainage lines and to remain unlogged.

In New South Wales, at least 28 species of native rodents have been recorded since European settlement. Four of these are extinct nationally, six are extinct in the State, six are vulnerable and four are endangered; only eight remain non-threatened. Declines and losses have been greatest in central and western New South Wales and least in the State’s north-east. Neither body weight nor habit are associated with status, but taxa such as Rattus species with broad diets and habitat preferences remain generally less threatened than ecological specialists. Threatening processes affect all vulnerable and endangered species, with predation from introduced carnivores, grazing from livestock, clearance of vegetation and changed fire regimes being among the most severe. No species occur entirely on reserved land, while two endangered species have no secure land tenure. A program of survey, research, management and education is proposed to help achieve recovery.

Spatial and temporal patterns of variability in ascidian assemblages were investigated on horizontal subtidal rocky reefs at Port Stephens, New South Wales (NSW). The study was designed to provide a baseline dataset on ascidian diversity and distribution patterns for an area destined to become a marine park (the Port Stephens–Great Lakes Marine Park: PSGLMP). Differences in ascidian assemblages between exposed oceanic island reefs and sheltered reefs within Port Stephens, and between two depth zones within each subtidal reef, were quantified using non-parametric multivariate techniques coupled with analysis of variance (ANOVA). Ascidian assemblages were highly variable between reef sites, reef exposures and particularly between depth zones within each reef surveyed. However, temporal variation was only observed for a few ascidian species. These highly variable spatial patterns in diversity indicate that numerous subtidal reefs may need to be protected within PSGLMP if the aim of the marine park is to adequately represent the entire array of marine biodiversity in the area.

Endangered Population

Context A population of yellow-bellied glider on the Bago Plateau, near Tumbarumba, was listed as an Endangered Population in 2008 under the New South Wales (NSW) Threatened Species Conservation Act 1995. The listing was based on limited data that suggested that the population is geographically and genetically distinct and its habitat in decline. Aims To review the validity of the endangered-population listing following the collection of new data on its distribution, habitat preferences and responses to logging. Methods Surveys for the yellow-bellied glider were conducted at a subset of sites established in 1995 on the Bago Plateau as well as across parts of the neighbouring Kosciuszko National Park, which had not been surveyed previously. The distribution of suitable habitat throughout these areas was evaluated. Key results The yellow-bellied glider was recorded at 29% of 48 sites resurveyed in 2010, 54% of which were previously occupied in 1995. Most changes in glider occupancy occurred at sites that had not been logged during the intervening period. The gliders preferred forest types dominated by montane gums (Eucalyptus dalrympleana, E. viminalis, E. camphora, E. pauciflora and E. stellulata) and used forest types of montane gums mixed with E. robertsonii or E. delegatensis in proportion to their availability across the landscape. The gliders were not observed to use monospecific stands of E. delegatensis. The yellow-bellied glider was also recorded frequently in Kosciuszko National Park. E. dalrympleana was consistently represented in the distribution of this species across the NSW Snowy Mountains. Conclusions Yellow-bellied glider site occupancy was not related to timber harvesting. Its habitat was not restricted by elevation or confined within Bago and Maragle State Forests by the Tumut River Gorge, Blowering and Talbingo Dams, as previously thought. We estimated that there is a large population of the gliders occupying up to 440 000 ha of contiguous habitat across the broader Snowy Mountains region of NSW, extending also into ACT and Victoria. Implications The listing of the Bago Plateau portion of this population as an endangered population appears inconsistent with relevant listing criteria and requires review.
