The program

Local help, close to home.

Many BC bats find roosts and shelters in tree cavities, crevices, exfoliating bark, or foliage, typically selecting the largest available old-growth trees and snags. Most bat species move frequently among several roosts to adjust for seasonal changes in weather and in response to disturbances.

When foraging or traveling, bats prefer to fly along habitat edges, with most activity concentrated in wetlands, riparian zones, or within natural openings in forested areas.
