Threats

Like all bats, Leisler's bat is vulnerable to a number of threats, including the loss of roost sites; in particular hollow trees are felled if thought unsafe or 'untidy'. Habitat change and loss, affecting the availability of insect prey and causing the fragmentation of feeding habitat is a serious problem for many bats, furthermore pesticide use has devastating effects, by causing severe declines in insect prey abundance, and contaminating food with toxins that may be fatal (3).

Conservation

In Britain, bats benefit from a very comprehensive level of legal protection (3). Under the Wildlife and Countryside Act it is illegal to intentionally kill, injure, take or sell a bat, posses a live bat or part of a bat, to intentionally (or in England and Wales, recklessly) damage, obstruct or destroy access to bat roosts. Under the Conservation Regulations it is an offence to damage or destroy breeding sites or resting places. Fines of up to £5,000 for every bat affected, and up to six months imprisonment are in place for these offences (7). Several species of bat can also benefit by bat boxes put up by the public.
