Australia's gliding possums depend on hollow-bearing trees and connected forest for their welfare, both of which are disappearing through logging and development.
Gliders trapped in isolated forest patches face chronic food stress as their eucalyptus foraging range is restricted. Greater gliders descending to cross open ground between trees face predation from foxes, cats and dogs. Nest hollow loss forces gliders into suboptimal sites with inadequate thermal insulation, increasing cold stress mortality in winter. Bushfire-induced canopy loss in 2020 eliminated habitat across millions of hectares simultaneously.
