Despite severe loss of, and damage to wetlands and waterways, Daubenton’s bat seems to be increasing in parts of its range.

This may in part be associated with the increasing number of artificial water bodies, including gravel pits, reservoirs and flooded quarries.

Also low level pollution may encourage a more consistent supply of favourable insects.

However, the loss of diversity of aquatic insects has a detrimental effect on other animals and, without very careful pollution controls, would also affect Daubenton’s bats.

The removal of waterside trees and disturbance to hibernation sites could also lead to a decline in this species.
