Background information and definitions
This intervention involves providing artificial nest sites for bats or improvements to bat roosts. Summer roost sites where bats rest during the day may be found in buildings, hollow trees, under bridges or in caves (Entwistle et al. 2001). Artificial roost sites in the form of bat boxes can provide additional roosting habitat, they are typically made of wood and may be placed on buildings or trees (Entwistle et al. 2001). Existing roosting sites may be protected from disturbance by installing bat grilles. Grilles allow bats to access their roost sites whilst excluding humans (Mitchell-Jones 2004).
