Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Geoffroy's Bat faces significant population declines across its European range due to the widespread loss and degradation of traditional roosting sites, particularly historic buildings, churches, and caves that undergo renovation or disturbance. Agricultural intensification has severely reduced insect prey availability through pesticide use and habitat simplification, while climate change is altering the timing of insect emergence, disrupting the species' carefully synchronized foraging patterns. Human disturbance at maternity roosts during the critical breeding season causes abandonment and reproductive failure, compounding population pressures.
