Wild Dormouse Decline and Hibernation Welfare

The hazel dormouse has declined dramatically in the UK and faces welfare challenges from climate change affecting hibernation cycles and food availability.

Key Facts

UK dormouse populations fell 70% between 1993 and 2018
Dormice hibernate for 7 months and are extremely sensitive to temperature fluctuations
Warm autumns can prevent dormice achieving sufficient weight before hibernation
Hazel coppice and hedgerow connectivity are essential habitat requirements
Nest tube monitoring programs track population trends and individual welfare

Welfare Considerations

Dormice face welfare harm from climate disruption to hibernation cycles - waking during warm winter periods burns critical fat reserves causing starvation. Habitat connectivity allowing access to diverse food sources throughout the active season is the primary welfare protection. Conservation management maintaining hazel coppice preserves this essential habitat.

What You Can Do

Support dormouse conservation programs including nest tube monitoring
Advocate for hazel coppice habitat restoration in your area
Create garden habitat with climbing plants and shrubs supporting dormouse food
