Species Greater horseshoe bat, Rhinolophus ferrumequinum, mammal
Habitat SPECIES-RICH HEDGES CALCAREOUS GRASSLAND
Background and status Nationally, the decline is said to have been about 99% over the last century, although in the last few decades a slight increase in numbers has occurred. There is now thought to be only 4000 - 6600 individuals restricted to South West England and South West Wales. There are currently 35 recognised maternity and all-year roosts and 369 hibernation sites.
Main Threats

Reductions in insect prey abundance, especially loss of old pasture due to high-intensity agricultural systems

Loss, destruction and disturbance of roosting and hibernation sites.

Loss of insect-rich feeding habitats and flyways, due to loss of wetlands and hedgerows and the conversion of permanent pasture to other arable.

Conservation and targets

Increase current population by 25% by 2010.

Maintain all existing maternity roosts and associated hibernation sites.

The greater horseshoe bat is the subject of an English Nature Species Recovery Programme, concentrating on feeding requirements. A project officer is employed in Devon to give advice to land managers, within the range of roost sites, on how to manage the land to benefit this species.
