Status
Reserve These bats are difficult to see or hear. Although not yet recorded on the reserve, they are almost certainly present, feeding amongst the trees.
Kent Widespread throughout the county.
Britain One of the three most common species in Britain.
Europe Abundant and widespread.
Conservation Has declined in Britain due to changing land use, which has resulted in loss of suitable feeding habitat and hollow trees for roosting. It is particularly susceptible to pesticides, including in roofs.
