4.2.5             Small population
The highly fragmented nature of the remaining Mahogany Glider habitat has resulted in numerous small isolated fragments that contain small numbers of Mahogany Gliders. The population viability studies undertaken on this species suggest that populations less than 800 individuals (within an estimated 8,000 ha) have an increasingly high probability of extinction as they get smaller (Jackson, 1999). These deleterious impacts include inbreeding that can result in a reduced genetic diversity causing inbreeding depression, and greater susceptibility to stochastic events such as cyclones (Caughley, 1994; Jackson, 1999).

4.2.6             Roads and easement corridors
The limited available information suggests that roads pose a potentially significant threat to the Mahogany Glider, with 15 road fatalities recorded between 1991 and 2005 (Smith, 1996; Parsons, 2005). Of the road kills recorded, almost all occurred on the Bruce Highway and appear to have been juveniles, suggesting that the width and volume of traffic on a road may be a barrier to dispersal (Parsons & Latch, 2006). Although the maximum recorded glide distance is 60 m (Jackson, 2000c), gaps in habitat across roads should ideally not be greater than the average glide distance of 30 m. In an attempt to mitigate road casualties, glider poles have been established in some areas to improve gliders' ability to cross safely. Roads also have a less
