Hazel dormice are enigmatic and endearing. They are also threatened with extinction. Join us in helping to bring them back from the brink.
Our national monitoring shows the population of hazel dormice has declined by half since 2000, with the species hanging on mostly in southern parts of England and Wales. Climate change, as well as changes in woodland management, farming practices and loss of hedgerows, have all taken a heavy toll on their living space. Dormice are good indicators of animal and plant diversity, and dormouse-friendly habitats are also good for woodland birds, bats and butterflies which is why we’re working hard to reverse the decline and promote recovery in British woodlands.
National Dormouse Footprint Tunnel Survey
The National Dormouse Footprint Tunnel Survey will be based on a search for dormice in hedgerows rather than any other habitat. Footprint tunnels are relatively easy to use and can be used by people who do not have a dormouse licence.
