Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
The Oak Click Beetle faces severe population declines primarily due to the loss and fragmentation of ancient oak woodlands across its range. Intensive forest management practices, urbanization, and climate change have dramatically reduced the availability of suitable dead wood habitats essential for larval development. Conservation status may vary by region or assessment authority, but the species remains highly vulnerable to continued habitat degradation.
Key Facts
Habitat & Distribution
Ancient oak woodlands and mature deciduous forests with abundant dead wood, fallen logs, and decaying tree stumps. The species requires old-growth forest conditions with substantial amounts of rotting oak timber where larvae can develop over multiple years.
