This open-air lecture and guided acoustic walk explores the bat species that inhabit Geneva’s parks. Participants learn how ultrasonic detectors and listening techniques reveal nocturnal activity, species presence, and behaviour. The session examines bats’ ecological roles, from insect control to ecosystem indicators, and discusses methods for monitoring and conserving urban bat populations. Attendees will gain a practical understanding of acoustic detection, species cues, and why protecting bat habitats matters for urban biodiversity.
