dissected by pine plantations.
2)        Cardwell Lowlands – Extends south from Cardwell and the Elphinstone Range to the Cardwell Gap, Mt Cudmore, where habitat is largely restricted to the foothills of the Cardwell Range.
3)        Broadwater – Extends from Mt Cudmore west towards the Herbert River Gorge, terminating at Yamanie Creek.
4)        Lannercost-Henrietta – Bounded by clearing associated with the Stone and Herbert Rivers.
5)        Wharps Holding-Paluma Range – Extends from Ollera Creek, the southernmost record of the glider, to the Stone River, where clearing along the river separates this subpopulation from the Lannercost-Henrietta subpopulation.
The 3 secondary subpopulations have a greater degree of habitat fragmentation than primary subpopulations, with little remaining internal connectivity. Consequently, their Mahogany Glider populations are unlikely to be viable in the longer term without an increase in connectivity. Strategic corridor and habitat plantings would greatly increase the viability of these subpopulations, and the value of these areas for the survival and persistence of the Mahogany Glider. These secondary subpopulations are:
6)        Upper Tully – Covers the balance of the northern-most habitat, west of the highway and north of the Tully River, towards Tully River Gorge.
7)        Hull Heads – Extends north of the Tully River, where rainforest starts to dominate the lowlands under a higher rainfall gradient and suitable glider habitat extends along the coast only as far north as Mission Beach, west to the foothill of Mount Mackay and bounded by the Bruce Highway.
8)        Halifax Bay – Extends east of the Pacific Highway near Ingham, between Cattle Creek and the Herbert River.
In the south and west of the Mahogany Glider's distribution, the climate becomes drier and the habitat becomes more marginal (and the Squirrel Glider becomes more prevalent). Two range limit areas were identified within the modelled distribution where the habitat is relatively intact, but there have been no confirmed sightings of the Mahogany Glider despite considerable search effort. These areas may become populated by the glider if the adjacent subpopulation expands. The 2 range limit areas are:
9)        Herbert River Gorge – Occurs within the confines of the Herbert River Gorge, where suitable habitat becomes relatively discontinuous and potentially less suitable, due to a rain-shadow effect, and the narrow steep topography of the gorge.
10)   Rollingstone – Occurs in the far south, beyond Ollera Creek, there is extensive lowland habitat on the coastal plain that appears suitable but there have been no sightings of the Mahogany Glider over a number of searches.
