Abstract:
The eastern barred bandicoot, Perameles gunnii, formerly occurred widely in Victoria and Tasmania. Because it is endangered in Victoria, clarification of its conservation and taxonomic status in Tasmania is important. We observed the distribution and relative abundance of Perameles gunnii in nine localities in Tasmania. Comparisons of trappability in three localities sampled in March 1985 and October- November 1989 showed no decline in relative abundance. P. gunnii were more abundant in November 1989 than on two previous occasions at one location. However, six other localities where P. gunnii were abundant in 1985 showed little evidence of P. gunnii activity in 1989. Spotlighting and trapping efforts, together with anecdotal information, suggest a decline in the status of P. gunnii in the Tasmanian Midland region. The reduction of these populations could be a feature of normal demographic fluctuation or could be indicative of a real decline in the status of P. gunnii. Long-term studies to monitor seasonal and annual abundance changes in Tasmania would be useful for the management of the dwindling Victorian population, and are needed to fully determine the status of Tasmanian populations for conservation and management purposes.

Abstract:
Totals of 32 female and 53 male Perameles gunnii were caught 241 and 330 times, respectively, during 4340 trap-nights at Hamilton, Victoria. Residents comprised 75.3% (n = 64) of the sample. Morphometric comparison indicates that P. gunnii is sexually dimorphic. Sex ratios (expressed in percentage of females) of 55% (dependent juvenile), 45% (independent juvenile) and 37.9% (adult) were determined. The age structure of the live-trapped population changed substantially between July 1989 (42.9% juvenile, 9.5% subadult and 47.6% adult) and August 1990 (46.2% juvenile, 15.4% subadult and 34.6% adult). The mean age of captured female bandicoots increased during the study, from 9.8 months in July 1989 to 15.8 months in August 1990. In all, 24 of 32 females produced 145 pouch young in 66 litters, with a mean W e . ) litter size of 2.2+/-0.1 (n = 66). The number of females that were lactating each month was high throughout the study (85%) and peaked during spring and autumn when all captured females were lactating. Sexual maturity for males and females occurred at about 5 and 3.5 months of age, respectively. The causes of mortality of P. gunnii between 1980 and 1990 included road death (63%, n = 85), cat predation (17.8%, n = 24), disease (8.1%, n = 11), trap death (5.2%, n = 7), machinery (3.7%, n = 5) and dog predation (2.2%, n = 3). A total of 25 P. gunnii died from unknown causes. Cat predation of P. gunnii may be high amongst juveniles and subadults but low for adults. A net emigration rate of 18% of individuals known to be alive indicates that the Hamilton Municipal Tip is a source for dispersal to other subpopulations. The 1990 distribution of the population was about 169 ha, within the City of Hamilton and adjacent Shire of Dundas, Victoria. There has been a decline in distribution and some local extinctions of P. gunnii in several areas between 1988 and 1990.

Abstract:
Once widespread throughout Victoria, the Eastern Barred Bandicoot Perameles gunnii has declined to near extinction on the Australian mainland due to habitat loss and predation by exotic predators. The last remaining wild population occurs in Hamilton, western Victoria. Founders for a captive breeding program were taken from this population in 1988, which has persisted without predator control or supplementation from captive-bred animals. The species was reintroduced to eight sites from 1989: Woodlands Historic Park, Hamilton Community Parklands, Mooramong, Floating Islands Nature Reserve, Lake Goldsmith, Lanark, Cobra Killuc, and Mount Rothwell. Although all reintroduced populations initially increased, declines were observed during the mid- to late 1990s, from which they have never recovered. A combination of drought and predation by Red Foxes Vulpes vulpes and Cats Felis catus is thought to be responsible. Currently, management techniques focus on intensive control of Red Foxes by poison baiting and shooting, and by construction and maintenance of predator barrier-fences at some sites. Understanding which characteristics lead to the success or failure of a reintroduction site is paramount to the success of the recovery programme for this species. This paper reviews the status of all reintroduction sites, and examines characteristics that could account for the performance of their populations.

Abstract:
On mainland Australia, eastern barred bandicoots (Perameles gunnii) are now restricted to a single wild population at Hamilton in western Victoria, and recovery efforts are focussed on establishing new populations at reintroduction sites. The success in founding these populations has been variable, and post-release survival has not been accurately quantified. It is believed that predation by the red fox (Vulpes vulpes) is largely responsible for post-release loss of P. gunnii, despite the implementation of predator control programs at release sites. An intensive fox control program was established to protect 10 released P. gunnii at Woodlands Historic Park, near Melbourne. Monitoring of fox activity was undertaken prior to and after the release in an attempt to better understand the effectiveness of control operations. Seven bandicoots were known to be alive at the conclusion of the study five weeks after their release (and an additional animal was trapped four months later), with weight loss appearing to be an important factor in determining post-release survival. Despite constant levels of bait-take by V. vulpes, fox activity measured from sand-pads remained high. We hypothesise that the presence of suitable refugia is allowing the persistence of a low-density bandicoot population at Woodlands despite constant, high levels of fox activity.

Abstract:
Perameles gunnii was greatly affected by the introduction of European agriculture to the volcanic plains in Victoria. At Hamilton, agricultural areas possessed little structural complexity and supported a fairly homogeneous composition of pasture species that were generally shorter than 100 mm because of heavy stock grazing. No P. gurznii were caught in agricultural areas at Hamilton. At the Hamilton Municipal Tip, most captures and nest sites occurred where food resources and structural complexity were greatest. Descriptions of 16 diurnal nest sites indicated that a range of natural and artificial materials was used for shelter, including fallen branches, sawn timber, cement culverts, galvanised iron, and scrap metal. Earthworms were most frequently observed in faecal and stomach material, while beetles and crickets were also common. Optimal habitat for P. gunnii was defined by high structural complexity and habitat heterogeneity. Older P. gunnii may usurp optimal habitat and force subordinate adult females into sub-optimal habitat. Associated with their occupation of optimal habitat, older P. gunnii may utilise smaller nocturnal foraging areas. Analysis of the movement of P. gunnii within the Hamilton Municipal Tip indicated that males occupied significantly larger nocturnal foraging areas than females. Mean female and male home ranges (defined by Minimum Convex Polygon analysis) were 1.6 ha (n = 13, range 0.02-5.9 ha) and 4 ha (n = 18, range 0.8-9.0 ha), respectively. Also, nocturnal foraging areas were analysed on the basis of pattern of use of an area, and these were referred to as utilisation distributions. The mean utilisation distributions (defined by Minimum Area v. Probability [0.95] analysis) for females and males were 0.64 ha (n = 13, range 0.01-4.7 ha) and 4.0 ha (n = 18, range 0.01-19.6 ha), respectively. Mean female and male observed range lengths were 173 m (tz = 26, range 0-364 m) and 249 m (n = 34, range 50430 m), respectively. Mean ( +/-s.e ) observed range length (214+/-20, n = 60, range 50-430 m) was less than half the grid width (500 m), which suggests that grid size did not negatively bias the calculated home-range sizes.

Abstract:
The threatened, free-ranging mainland poplation, of the eastern barred bandicoot in the Hamilton area of Victoria declined to near extinction in late 1992. Demographic changes associated with the decline were monitored from 1988 to 1992. About 200 different animals were captured in 1988,49 in 1989, 16 in 1990, 3 in 1991 and 3 in 1992; capture rates (number of bandicoots captured per trap-night) displayed a similar pattern: 0.5 in 1988,O.l in 1989,0.05 in 1990,0.05 in 1991 and 0.02 in 1992. Observed declines lay within the 5% confidence intervals predicted by a demographic model for a population subjected to a removal rate of 14 animals per three months (the number removed for captive breeding by managers). Removal of bandicoots to stock a captive population hastened the demise of the wild population by about seven years; however, even in the absence of removals of animals, extinction was impending within 5-10 years. Sex ratios were male-biased in all years except 1988; the bias may have resulted from stochastic events. Average litter sizes did not differ between the 1988 population and subsequent populations, except for the 1991 population, in which a predominance of non-reproductive females contributed to a strong decline in average litter size. These demographic trends illustrate how the synergy between stochastic and deterministic forces can rapidly drive a small population to extinction.

Abstract:
On the Australian mainland, the eastern barred bandicoot is now restricted to the city of Hamilton in western Victoria. Mark-recapture data from four main population areas, used in a Petersen index, gave a population estimate of about 134 individuals in 1988. When areas not sampled for population abundance were included, the total estimate of abundance for Hamilton was 246 individuals. Sex ratio was significantly male-biased for adults (68%), whereas the sex ratio for pouch young was about equal (45% male). The subadult age class constituted 8.2% of the captures, and accounted for only 10% of the total number of pouch young produced. Mean litter size was 2.11. The number of lactating females and the litter size were greatest during early spring. Eighty per cent of the offspring were produced in litters of 2 or 3. Nests were observed in various substrates, including man-made structures. Selected foraging areas had few native grasses, high ground cover, tall plant height and acid soils of low to medium compaction. Bandicoots were observed feeding on invertebrates, with some orchard fruits also being eaten. Foraging patches were actively defended. Adult home ranges of males (mean 12.94 ha) were larger than those of females (mean 2.38 ha). No female moved more than 150 m whereas males moved up to 2.3 km from their initial point of capture. The major cause of adult mortality observed was road kills. Life-expectancy is probably less than 2 years. Juvenile mortality was high.

Abstract:
The Eastern Barred Bandicoot is one of Australia's most threatened species. When their existence came under extreme threat from habitat loss, predators and human development, Eastern Barred Bandicoots found refuge in the most unlikely of places – a rubbish tip. This captivating true story details the plight these small, nocturnal marsupials faced, and the outstanding efforts that ensured their protection. Written by Rohan Cleave and illustrated by Coral Tulloch, Bouncing Back shows that even on the brink of extinction, there is hope for the survival of our most vulnerable species. Rohan Cleave and Coral Tulloch's first book, Phasmid: Saving the Lord Howe Island Stick Insect, won a Whitley Award for Children's Natural History Book and was an Honour Book in the Children's Book Council of Australia Book Awards (Eve Pownall Information Book category). Bouncing Back is perfect for primary aged readers.
