Wild Dormouse: Nest Box Monitoring and Hibernation Welfare

Hazel dormice require specific habitat and nest box provision to support welfare through hibernation and breeding.

Key Facts

UK hazel dormouse populations declined by 72% between 1993 and 2023
Dormice hibernate from October to April and require undisturbed hibernation sites
Nest box schemes in suitable coppiced woodland successfully support breeding populations
Dormice are highly sensitive to cold snaps during emergence from hibernation

Welfare Considerations

Dormice disturbed during hibernation burn critical fat reserves and may die from cold exposure. Nest box monitoring following strict protocols protects individual welfare. Connecting dormouse populations through hedgerow restoration reduces isolation stress and inbreeding.
