Natural Predator
The night owl is the gliders only natural predator in Tasmania. It swoops on the glider in flight and snaps off its tail, sending it plummeting to the ground, to become easy prey. Glider tails are regularly spotted by bushwalkers.
New Predators and problems of the 1900's
- The cat - both feral and domestic
- The dog - both feral and domestic
- Increases in numbers of introduced European rat
- European wasps competing for tree hollows
- Rural land clearing robs them of feeding and breeding sites
- Logging and wood chipping of old growth forest
- Monoculture tree plantations (non-flowering)
- Changing weather patterns have driven them into suburbia
