Providing bat houses supports declining bat populations by offering roosting habitat. Understanding bat needs helps create effective structures that benefit colony welfare.
Bats face severe welfare challenges from habitat loss, white-nose syndrome, wind turbine mortality, and roost disturbance. The social nature of bat colonies means roost loss affects many individuals simultaneously. Maternity colony disruption during pupping causes abandonment of dependent pups, resulting in their starvation. Provision of quality artificial roosts offsets some habitat loss and supports population recovery. Insectivorous bats provide enormous ecosystem services and their welfare matters both intrinsically and for the ecosystems they support.
