Key messages

  • One study evaluated the effects of engaging farmers and landowners to manage land for bats on bat populations. The study was in the UK.

COMMUNITY RESPONSE (0 STUDIES)

POPULATION RESPONSE (1 STUDY)

  • Abundance (1 study): One study in the UK found that during a five-year project to engage farmers and landowners to manage land for bats, the overall population of greater horseshoe bats at four maternity roosts in the area increased (but see summary below).

BEHAVIOUR (1 STUDY)

  • Change in human behaviour (1 study): One study in the UK found that a landowner engagement project resulted in 77 bat-related management agreements covering approximately 6,536 ha of land.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A study in 1995–2003 of the greater horseshoe bat project in England, UK (Longley 2003) found that the landowner engagement project resulted in 77 bat-related management agreements covering approximately 6,536 ha of land in Devon, Cornwall, and Somerset. This included 80 km of new/restored hedgerow and 400 ha of grassland within key areas surrounding greater horseshoe bat Rhinolophus ferrumequinum maternity roosts. The overall population of greater horseshoe bats at four maternity roosts in Devon was found to increase by 58% in 1995–2003, although the authors note that it is difficult to directly attribute this increase to the project. Advice was provided to 163 landowners and five organisations during farm visits, training seminars and farm walks. Support was also provided with grant applications. The project was widely publicised in the press (24 articles) and TV/radio (five programmes).
