Abstract:
The rate and spatial scale at which natural environments are being modified by human land-uses mean that a regional or national perspective is necessary to understand the status of the native biota. Here, we outline a landscape-based approach for using data from the ‘New Atlas of Australian Birds’ to examine the distribution and status of avifauna at a regional scale. We use data from two bioregions in south-east Australia – the Gippsland Plain and the Strzelecki Ranges (collectively termed the greater Gippsland Plains) – to demonstrate this approach. Records were compiled for 57 landscape units, each 10′ latitude by 10′ longitude (~270 km2) across the study region. A total of 165 terrestrial bird species was recorded from 1870 ‘area searches’, with a further 24 species added from incidental observations and other surveys. Of these, 108 species were considered ‘typical’ of the greater Gippsland Plain in that they currently or historically occur regularly in the study region. An index of species ‘occurrence’, combining reporting rate and breadth of distribution, was used to identify rare, common, widespread and restricted species. Ordination of the dataset highlighted assemblages of birds that had similar spatial distributions. A complementarity analysis identified a subset of 14 landscape units that together contained records from at least three different landscape units for each of the 108 ‘typical’ species. When compared with the 40 most common ‘typical’ species, the 40 least common species were more likely to be forest specialists, nest on the ground and, owing to the prevalence of raptors in the least common group, take prey on the wing. The future status of the terrestrial avifauna of the greater Gippsland Plains will depend on the extent to which effective restoration actions can be undertaken to ensure adequate representation of habitats for all species, especially for the large number of species of conservation concern.

Abstract:
Toothed Leionema is one of four subspecies of Leionema bilobum from the Rutaceae family. A dense shrub or small tree, growing to ~4 m high, it is a poorly investigated species which is considered rare in Victoria, Australia. This paper presents the results of a study using Geographical Information Systems and Weights-of-Evidence predictive modelling to assess the importance of seven environmental factors in determining habitat suitability for this species in the Strzelecki Ranges, Victoria. This method is particularly useful in understanding the distribution of rare species, especially where the ecology of the species of interest is not well understood. Of the seven environmental factors considered here, four were found to be important: elevation, aspect, distance to water and distance to plantation (disturbed) areas. The modelling results indicate that areas with elevations between 350 and 550 m and a dominant south-western aspect that are close to plantation areas (within 700 m), and to water (within 1100–1200 m), provide potentially suitable habitat for Toothed Leionema in the region.

Abstract:
The nesting requirements of the yellow-tailed black-cockatoo (Calyptorhynchus funereus) were studied at 68 sites in Eucalyptus regnans forest in the Strzelecki Ranges, South Gippsland, Victoria. Nest trees were located and their characteristics related to forest stand variables. Eighteen nest hollows were found. Nest trees had a mean diameter at breast height of 2.5 m, a mean estimated age of 221 years, a mean height of 58 m and for live nest trees a mean crown diameter of 22 m. The currently proposed rotation time for silvicultural systems of 80-150 years will reduce the number of hollow-bearing trees suitable for nesting yellow-tailed black-cockatoos. Adequate numbers of trees must be retained in logged areas and wildlife corridors and reserves, and protected to ensure a continual supply for yellow-tailed black-cockatoos and other hollow-dependent species. If agonistic behaviour is operating between female yellow-tailed black-cockatoos, nesting potential may be enhanced if trees retained on coupes are evenly distributed rather than clumped. Silvicultural systems that facilitate the protection of trees retained on coupes would benefit the conservation of the yellow-tailed black-cockatoo.

Abstract:
In many suburban parts of Australia the removal of snakes from private property by licenced snake catchers is employed to mitigate perceived risks to humans and their pets. The number of snakes translocated around greater Melbourne, Victoria, each year can be very high (at least many hundreds). However, the effects of translocation on the behaviour and welfare of individual snakes, and the impact on existing snake populations at release sites are unknown. We used radio-telemetry of ‘resident’ and translocated snakes to investigate the consequences of translocation on the spatial ecology of tiger snakes (Notechis scutatus) in a suburban parkland near Melbourne. Fourteen snakes (two female and four male residents, and four female and four male translocated snakes) implanted with radio-transmitters were tracked between spring 2002 and autumn 2003. Translocated snakes exhibited home ranges ~6 times larger than those of residents, although each group maintained core ranges of similar size. Translocated snakes travelled longer distances and were often located in residential areas adjacent to the park, whereas resident snakes were never located outside of the park.

Abstract:
Shiny Nematolepis Nematolepis wilsonii is a small understorey tree endemic to Victoria, south east Australia. The species is listed as threatened due to its limited distribution and low abundance. The sole known population, of approximately 400 metres individuals, is located in the Yarra Ranges National Park, Victoria. Paired exclusion plots were erected to investigate the impact of antler rubbing and thrashing activities of Sambar Cervus unicolor on Shiny Nematolepis. Sambar rubbing activities removed, on average, over half the circumference of bark down to the cambium of mature trees. Rubbing damage covered a range of tree sizes, with rubbed individuals in significantly poorer health and exhibiting 19% less relative foliage cover than non-rubbed individuals. Saplings selected by Sambar for thrashing had a significantly greater stem diameter and were most commonly situated beside the road. Other forms of damage to Shiny Nematolepis included storm events and biting by Yellow-tailed Black Cockatoo Calyptorhynchus funereus, but Sambar pose an added threat, which is likely to result in further decline of this threatened population.

Abstract:
To investigate movements and habitat selection by wild dogs we attached satellite-linked global positioning system (GPS) units to nine wild dogs (Canis lupus dingo and Canis lupus familiaris) captured in eastern Victoria in summer 2007. Units estimated locations at 30-min intervals for the first six months and then at 480-min intervals for six more months. DNA testing revealed all these wild dogs to be related. Home ranges of males were almost three times larger than those of females (males: 124.3 km2 ± 56.3, n = 4; females: 45.2 km2 ± 17.3, n = 5) and both sexes preferred subalpine grassland, shrub or woodland at the landscape and home-range scales. Wild dogs were recorded more often than expected within 25 m of roads and less often than expected within 25 m of watercourses. Wild dogs displayed higher-velocity movements with shallow turning angles (generally forwards) that connected spatial and temporal clusters comprising slower-velocity, shorter, and sharper turning movements. One wild dog travelled 230 km in 9 days before returning to its home range and another travelled 105 km in 87 days. The home-range sizes reported in this study are much larger than previously reported in south-eastern Australia. This finding, together with previous studies, suggests that the spatial scale at which wild dog management occurs needs to be reconsidered.

Full text
Abstract:
Conservation and planning for threatened species requires knowledge of the species? spatial distribution, prefered habitat and response to disturbance factors such as fire. The white-footed dunnart (Sminthopsis leucopus) is currently listed as ?Vulnerable? due to its patchy distribution, the low density of populations and extinction threats. Studies of the species have been limited, and the aims of this study were to investigate the spatial distribution with relationship to landscape, habitat and fire factors. The study was undertaken in the Eastern Otway Ranges, southern Victoria where the species was recorded at 42 sites (44% of survey sites). The sites were all located within 10 km of the coast, and located in vegetation ranging from sclerophyll communities (forest, woodland and heathland) to coastal shrublands dominated by sedges and grasses. Logistic regression models were generated for species occurrence and predictor variables. The most parsimonious model was selected and although there was an association between presence of S. leucopus with landsystem and altitude, support for the models was not strong. The relationship with altitude was negative, indicating a preference for lower elevations. Models developed for other fauna species have identified landscape variables as being strongly predictive of occurrence, indicating that variables other than those investigated may be more suitable in predicting occurrence of S. leucopus at a landscape level. S. leucopus was recorded at a high percentage of sites 6-15 years post-fire age, and at maximal relative abundance at 4-9 years, providing evidence that it prefers mid succession habitats.

Abstract:
Abstract Dasyurids are small mammals that can conserve energy and water by using shelters that insulate against extreme conditions, prevent predation, and facilitate torpor. To quantify the diurnal sheltering requirements of a poorly known, endangered dasyurid, the sandhill dunnart, Sminthopsis psammophila, we radiotracked 40 individuals in the Western Australian Great Victoria Desert between 2015 and 2019. We assessed the effect of habitat class (broad habitat features), plot-level (the area surrounding each shelter), and shelter characteristics (e.g., daily temperature ranges), on shelter selection and sheltering habitat preferences. Two hundred and eleven diurnal shelters (mean of 5 ± 3 shelters per individual) were located on 363 shelter days (the number of days each shelter was used), within mature vegetation (mean seral age of 32 ± 12 years postfire). Burrows were used on 77% of shelter days and were typically concealed under mature spinifex, Triodia spp., with stable temperature ranges and northern aspects facing the sun. While many burrows were reused (n = 40 across 175 shelter days), spinifex hummock shelters typically were used for one shelter day and were not insulative against extreme temperatures. However, shallow scrapes within Lepidobolus deserti hummock shelters had thermal advantages and log shelters retained heat and were selected on cooler days. Sminthopsis psammophila requires long-unburned sheltering habitat with mature vegetation. Summer fires in the Great Victoria Desert can be extensive and destroy large areas of land, rendering them a key threat to the species. We conclude that the survey and conservation of S. psammophila requires attention to long-unburned, dense lower stratum swale, sand plain, and dune slope habitats, and the tendency of S. psammophila to burrow allows the species to survive within the extreme conditions of its desert environment.
