UK Dormouse Conservation: Microhabitat Needs

The hazel dormouse is declining across the UK due to habitat fragmentation, with welfare implications for one of Britain's most charming native mammals.

Key Facts

UK dormouse populations declined by 51% between 1995 and 2016
Dormice require a mosaic of woodland edge, hazel coppice, and dense hedgerow habitat
Hibernation from October to April makes them vulnerable to mild winters caused by climate change
Dormice are protected under the Wildlife and Countryside Act and European Habitats Directive

Welfare Considerations

Individual dormouse welfare is affected by food availability in the period before hibernation and by winter temperature instability that can cause mid-hibernation arousal, depleting fat reserves. Habitat restoration and corridor creation are the most impactful welfare and conservation interventions.

What You Can Do

Support woodland management schemes that include hazel coppice management
Join dormouse nest tube monitoring programmes in suitable habitat
Advocate for hedgerow protection and restoration in agricultural planning
