Collected Evidence: Collected Evidence: Retain riparian buffers on agricultural land One study evaluated the effects of retaining riparian buffers on agricultural land on bat populations. The study was in the UK. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Abundance (1 study): One replicated, paired sites study in the UK found that pipistrelle activity (relative abundance) did not differ along waterways with buffers of vegetation on agri-environment scheme farms and waterways on conventional farms.

Therefore we have no evidence to indicate whether or not the intervention has any desirable or harmful effects.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2285https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2285Tue, 19 Nov 2019 18:23:58 +0000Collected Evidence: Collected Evidence: Restore bat foraging habitat at ex-quarry sites One study evaluated the effects of restoring bat foraging habitat at ex-quarry sites on bat populations. The study was in France. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Abundance (1 study): One replicated, site comparison study in France found that gravel-sand pits had higher overall bat activity (relative abundance) 10 years after restoration than gravel-sand pit sites before or during quarrying.

The study was in Canada. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Survival (1 study): One replicated, randomized, controlled study in Canada found that bat fatalities were reduced when turbine blades were slowed at low wind speeds.

COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (0 STUDIES) BEHAVIOUR (1 STUDY)         Use (1 study): One review in the USA found that bat houses provided as alternative roosts during bridge replacement works were used by fewer Mexican free-tailed bats than the original roost at one site and were not used by bats at all at three sites.
