- Bats appear to be resilient to forest fires, and some species may even benefit from the effects of fire on the landscape.
The results showed that the responses of the six phonic groups to moderate and high-severity fire were either neutral or positive. The heterogeneity such fires create in the landscape may be an important feature, resulting in a habitat structure that benefits a range of species, Frick said.
"Bats could be resilient to this kind of natural disturbance," she said. "We go out there and see a charred landscape and we think it's totally destroyed, but the bats may find it a productive habitat for their needs."
Some species seem to prefer burned areas for foraging. This could be due to reduced clutter and increased availability of prey and roosts after a fire, although further research on these topics is needed, according to coauthor Michael Buchalski, a doctoral student at Western Michigan University. "Fire may provide a pulse of insects immediately after the fire and create roosting habitat later on as snags decay and their bark peels back," he said.
Buchalski and Fontaine share first authorship of the paper. Frick led the survey of echolocation activity, and coauthors Paul Heady of the Central Coast Bat Research Group and John Hayes of the University of Florida also contributed to the study.
