between species (Jackson, 2001; Goldingay & Jackson, 2004).
The primary genera of trees utilised to obtain nectar and pollen include Corymbia, Eucalyptus and Melaleuca of the family Myrtaceae (Van Dyck, 1993; Jackson, 2001). The only rainforest species known to be utilised for nectar and pollen include the Cadargi (Corymbia torelliana) and Euodia (Melicope elleryana) on the edge of rainforest and in riparian forest (Van Dyck, 1993; Jackson, 1998; 2001). The importance of pollen as a source of protein in the diet was confirmed by several studies that discovered that between 30 and 99% of the contents of pollen grains consumed are digested (Dettman et al., 1995; Jackson, 2001).
Other important food items include sap from the tree White Siris (Albizia procera) and Hickory Wattle (Acacia mangium), and arils from the seed pods of the Thick-podded Salwood (Acacia crassicarpa), Red Wattle (A. flavescens) and Hickory Wattle (A. mangium). A variety of insects are also eaten, as well as lerps (coverings or testa excreted by the nymphs of psyllids, under which they shelter and feed); honeydew (sugary waste excreted by psyllids on the leaves and other parts of the plant on which they feed); and fruit from mistletoes of the family Loranthaceae (Van Dyck, 1993; Jackson, 2001). Nectar and sap from the flower spikes of Johnson's Grass Tree (Xanthorrhoea johnsonii) are important when these are available (Van Dyck, 1993). The diet of the Mahogany Glider relies on complex seasonal cycles of food availability requiring a high diversity of plants, with each species having distinct periods when it provides food during the year (Jackson, 2001).

3.2.3             Movement patterns and habitat use
The home-range of the Mahogany Glider is on average 19 ha for males and 20 ha for females in contiguous habitat, while male and female pairs occupy a combined area of approximately 23 ha. Observations of the home-range in fragmented habitat has recorded this to be as low as 11 ha for males and 7 ha for females, with a combined home-range of male and female pairs being 12 ha (Jackson, 2000b). Paired male and female home-ranges overlap with each other by approximately 86%, compared with only 11% for non-paired individuals. This finding suggests that this species is socially monogamous (Jackson, 2000b). The density of Mahogany Gliders averages 0.24 individuals/ha in contiguous forest and 0.16 individuals/ha in fragmented habitat (Jackson, 2000a). These densities appear to reflect their large home-ranges and the limited overlap with non-paired animals and are typically lower than sugar and squirrel gliders, but not as low as observed in the yellow-bellied glider (Goldingay & Jackson, 2004).
In traversing their home-ranges, the Mahogany Glider is highly mobile, travelling an average distance of 1,500 m (range from 600 to 3,400 m)
