The tiny Leadbeater’s possum is critically endangered from a combination of habitat destruction, timber harvesting, the effects of high-intensity forest fires, and habitat fragmentation from roads and fire-breaks. We tested two different designs of canopy bridges across roads in their forest habitat and both were used, reducing the risk of predation by terrestrial predators and wildlife-vehicle collision.

Conservation landscapes are often frequently visited by tourists wanting to interact with wildlife, which can also increase threatening processes such as wildlife-vehicle collisions. Understanding how roadkill rates change with increasing tourism, and wildlife abundances concurrently, could help to identify successful mitigation measures which could be implemented pre-emptively.

Lighting in wildlife underpasses significantly reduces their use by bats. Bats are more likely to cross the road rather than use the underpasses when they are lit, greatly increasing their risk of mortality.
