Introduce agri-environment schemes
A replicated, site comparison study in 2008 of 18 paired pasture fields in Devon, UK (MacDonald et al 2012) found that fields under agri-environment scheme management had similar bat activity as fields under conventional management. There was no significant difference in the overall number of bat passes recorded over agri-environment scheme fields (average 3 passes/night) and conventionally managed fields (1 pass/night). Seven bat species were recorded in total (see original paper for data for individual species). Paired agri-environment scheme fields and conventionally managed fields were matched where possible by topography, size and landscape context. Agri-environment scheme fields were managed with no pesticide or fertiliser inputs. Conventionally managed fields had no management restrictions. Bat activity was recorded using bat detectors at each pair of fields for 1–2 full nights in May, July or August 2008.
