|Scientific Name:||Petaurus australis|
|Species Authority:||Shaw, 1791|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Assessor(s):||Woinarski, J., Burbidge, A.A. & Johnson, C.N.|
|Contributor(s):||Menkhorst, P., Quin, D., Goldingay, R., Eyre, T., Lindenmayer, D., Lunney, D. & Winter, J.|
Listed as Near Threatened because the few ongoing monitoring programs demonstrate decline in population size and/or area of occupancy that may approach 30% over a three generation period, because it is likely to face ongoing decline because of legacy impacts of habitat fragmentation, recent increases in land clearing in the Queensland parts of the distribution, and because habitat quality continues to be affected by inappropriate fire regimes and/or logging. For these reasons the species may be close to meeting the requirements for listing as Vulnerable under criteria A2bc+3bc+4bc.
|Previously published Red List assessments:|
|Range Description:||The Yellow-bellied Glider is endemic to eastern Australia, where it occurs from the Mount Windsor tablelands (Queensland) in the north to the Victoria/ South Australia border (Goldingay 2008). There is a distributional gap of about 400 km between the undescribed Wet Tropics subspecies and nominate subspecies.|
Native:Australia (New South Wales, Queensland, South Australia, Victoria)

|Population:||There is no reliable estimate of population size. Maxwell et al. (1996) considered it ‘uncommon throughout range’. Carthew (2004) estimated that there were (then) only six individuals present in South Australia, in a single 200 ha forest patch. It typically occurs at low densities (0.05-0.14 individuals/ha: Kavanagh 1984; Henry and Craig 1984; Craig 1985; Goldingay and Kavanagh 1991; Goldingay and Jackson 2004).|
Many subpopulations have been extirpated (e.g. Carthew 2004) and the key threats are likely to continue.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:|
The Yellow-bellied Glider occurs in eucalypt-dominated forests and woodlands. Habitat suitability is determined in part by floristics, with a clear preference for forest types dominated by gum-barked and winter-flowering eucalypts (Kavanagh 1987; Eyre and Smith 1997; Eyre 2004), and with forest age sufficient to provide suitable trees for shelter and foraging (Milledge et al. 1991; Incoll et al. 2001; Eyre and Goldingay 2003). The Yellow-bellied Glider is reliant on large areas of mature forest (Milledge et al. 1991; Eyre and Smith 1997; Lindenmayer et al. 1999a; Incoll et al. 2001; Eyre 2002, 2004; van der Ree et al. 2004).
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||4.5|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Habitat loss and fragmentation due to timber-harvesting and agriculture are the main threats to this species. Due to past forest management there is a current dearth of available live hollow-bearing trees within Yellow-Bellied Glider habitats. Remaining hollow-bearing trees are therefore an important resource, but these are at risk of collapse due to regular prescribed burning regimes and windthrow. In Queensland and New South Wales (and possibly Victoria) broad-scale land clearing had been stopped due to newly introduced vegetation management legislation However, in Queensland relaxation of this legislation during the last three years has resulted in a sharp increase in forest clearing since 2013 (see https://theconversation.com/land-clearing-in-queensland-triples-after-policy-ping-pong-38279). The effects of this recent change on Queensland populations of the Yellow-bellied Glider have not yet been specifically evaluated, but they are potentially significant. Furthermore, degradation to existing habitat (e.g., through fire, timber removal) within the habitat of isolated populations, but also between non-isolated populations, is a major threat to the species (essentially inducing a fragmentation effect) throughout its range, due to its wide-ranging and extensive habitat requirements (Woinarski et al. 2014).|
|Conservation Actions:||This species is present in a number of protected areas. Management of timber such that large areas of intact, contiguous forest remain is important for this species. Currently sap trees must be identified and preserved, but the effectiveness of this measure is uncertain (Goldingay 2008). Timber-harvesting and fire management should be aimed at maintaining tree-hollows and extensive areas of suitable forest.|
