Create artificial caves or hibernacula for bats
A study in 2004–2006 at a wetland nature reserve in Cambridgeshire, UK (Gulickx et al 2007) found that an artificial cave was used by 1–2 hibernating brown long-eared bats Plecotus auritus in each of two years after construction. Bats were found hibernating attached to the cave roof or in between the concrete cave roof sections. The cave (2 m wide x 2 m high x 30 m long) consisted of a trench dug into the underlying limestone with a pre-cast concrete roof containing elongated bat bricks with six gaps in each. A door made of steel and oak boards was constructed to restrict access by predators and humans. Two slots in the top of the door allowed bats to pass through and a fine wire mesh on the bottom of the door allowed air flow. The cave was installed in 2004 and inspected for bats in 2005 and 2006.
