Urban bat populations face specific welfare challenges and require legal protection of roost sites during building development.
Urban bat welfare is compromised by development that destroys roosts, lighting that disrupts foraging, and fragmentation of commuting routes between roost sites and feeding areas. Bats cannot simply relocate when roosts are destroyed - maternity colonies and hibernation sites represent irreplaceable welfare resources. Legal protection of bat roosts is essential and must be effectively enforced to have welfare meaning.
