The researchers used acoustic surveys to test the effects of burn severity and variation in fire effects, or pyrodiversity, on 17 species of bats in the region. Individual species responded to wildfire differently, but overall species richness increased from about eight species in unburned forests to 11 species in forests that experienced moderate- to high-severity burns.
