Flying foxes are threatened by over-hunting and deforestation. They are hunted as exotic meat and also consumed as a traditional cure for asthma. Previously, it was thought that flying foxes eat up the flowers of the durian tree and many orchard owners set up nets to trap them.

Studies using camera traps have confirmed that these bats are probably the most effective pollinators for durian trees.

Pollen sticks to their fur as they feed on the nectar, and is transferred when they move off to feed on the flowers of another tree. If flying foxes were to go extinct one day, so might durians. That alone is reason enough to conserve them.
