Assessment
species while waiting to ambush prey. Weed and pest species that may act as disease vectors will be managed as per the EMP. As such, the Project is not considered likely to introduce disease that may cause the species to decline. While potential foraging habitat will be removed, similar quality habitat remains widely available throughout the region. Ecological surveys did not identify any potential breeding or denning habitat within the project area. Whilst there is the potential for the project area to be used by ghost bats for foraging and/or dispersal, it is unlikely a population will occur within the project area and therefore it is unlikely any project related impact could interfere with the recovery of the species. As such, the project is considered unlikely to interfere with the recovery of the species. While potential foraging habitat will be removed, similar quality habitat remains widely available throughout the region. Ecological surveys did not identify any potential breeding or denning habitat within the project area. The Mt Etna colony likely fulfils the regions breeding requirements making it unlikely that the tunnel within the project area functions as a maternity roost. As such, the project is considered unlikely to cause disruption to ecologically significant locations (breeding, feeding, nesting, migration or resting sites) of a species.

6.9.1.4. Greater glider (southern and central) (Petauroides volans)
The greater glider (southern and central) ( Petauroides volans ) is listed as vulnerable under the EPBC
Act and NC Act.
The species is restricted to mature eucalypt forests and woodlands with an abundance of mature, hollow
bearing trees (Andrews et al., 1994; Kavanagh, 2000; Eyre, 2004; Van der Ree et al., 2004; Vanderduys
et al., 2012). The species has a specialist folivorous diet and displays seasonal food preferences (Kehl
and Borsboom, 1984; Kavanagh and Lambert, 1990). As a result, the species requires access to forests
with a diversity of tree species to provide a consistent food source throughout the year (Kavanagh,
1984). The species dens in large hollows in mature trees (Henry, 1984; Lindenmayer et al., 1991;
Goldingay, 2012). The availability of mature, hollow-bearing trees is a limiting factor. The species has
been found to be absent from forests with fewer than six hollow-bearing trees per hectare (Smith et al.,
1994). The species has a relatively small home range, typically 1 – 4 ha (Henry 1984; Comport et al.
1996; Gibbons and Lindenmayer, 2002). Given the species’ limited capacity for dispersal, and
reluctance to cross vegetation gaps, it is sensitive to habitat fragmentation (McCarthy and Lindenmayer,
1999).
The nearest historical record of a greater glider (from 1881) is located approximately 5 km south of the
project area (DETSI, 2025). Given that the project area is connected to a large, continuous tract of
potential habitat, with unknown availability of tree hollows, the species has the potential to occur within
the project area.
