Dormouse Habitat and Conservation

The hazel dormouse is one of Britain's most charming and threatened mammals. Its welfare and conservation depend on maintaining complex woodland edge habitats.

Key Facts

Hazel dormouse populations in Britain have declined by 70% over the last 25 years
They depend on continuous scrubby woodland edge with diverse flowering and fruiting shrubs
Dormice hibernate from October to April and enter torpor during cold summer spells
Nest boxes in suitable habitat provide important supplementary nesting sites for monitoring
Licensed handling for monitoring is strictly controlled due to their protected status

Welfare Considerations

Dormice face welfare challenges from habitat loss that forces them into suboptimal areas with insufficient food diversity. Interrupted hibernation in mild winters increases energy expenditure, threatening survival. Disturbance of hibernation nests by gardening or woodland management causes stress and energy loss. Conservation management that maintains diverse scrubby woodland edge with continuity enables dormice to meet their complex habitat needs across seasons.

What You Can Do

Support woodland and hedgerow management charities maintaining dormouse habitat
Install licensed dormouse boxes in suitable habitat and participate in monitoring schemes
Avoid disturbing leaf litter and scrubby base vegetation in dormouse habitat during winter
Plant dormouse-friendly shrubs including hazel, honeysuckle, and bramble in garden settings
Report dormouse sightings to local wildlife trusts to improve distribution data
