Bechstein Bat: Ancient Woodland Specialist

Bechsteins bat is one of Europes rarest bats in Britain restricted to ancient woodland with abundant tree cavities.

Key Facts

Bechsteins bat is one of Europes rarest bats with perhaps fewer than 1,500 in Britain
They depend entirely on old trees with natural cavities for roosting and hibernation
Bechsteins bats are short-winged and highly manoeuvrable for hunting inside dense woodland
They form small maternity colonies of up to 30 females in tree cavities
UK population is mainly in southern England in areas of ancient woodland

Welfare Considerations

Bechsteins bats face extreme welfare vulnerability from loss of ancient woodland and veteran trees with natural cavities. Tree felling eliminates roosting habitat for this cavity-dependent species. Woodland management that removes standing dead wood and veteran trees is particularly damaging. Bat box provision is less suitable as Bechsteins bats prefer natural cavities. Disturbance during hibernation in hollow trees can cause fatal energy expenditure.

What You Can Do

Support ancient woodland protection and veteran tree retention programmes
Install multiple bat boxes of varying designs in woodland as supplementary roost sites
Never disturb trees with potential bat roost features without surveying first
Support Bat Conservation Trust Bechsteins bat research and monitoring
Donate to Woodland Trust campaigns to protect ancient woodland from development
