Wild Dormouse Ecology and Welfare

The hazel dormouse has undergone major population decline in the UK. These charming nocturnal mammals depend on diverse woodland edge habitats for foraging and hibernation.

Key Facts

Dormice populations have declined by approximately 70% in the UK since the late 1990s
Dormice rely on diverse woodland with hazel, honeysuckle and bramble for food and nesting
Hibernation from October to April makes dormice particularly sensitive to mild autumn conditions
Dormouse nest tubes are used in monitoring and can support populations in managed habitats
Climate change is disrupting hibernation timing, posing new welfare and survival risks

Welfare Considerations

Dormouse welfare and conservation depend on habitat quality and connectivity. As climate change alters hibernation behaviour, welfare risks from premature arousal and food scarcity are increasing.

What You Can Do

Support People's Trust for Endangered Species dormouse conservation programmes
Plant native hedgerows with hazel, honeysuckle and bramble to create dormouse habitat
Report dormouse sightings to local wildlife trusts to support range monitoring
