Hazel Dormouse Welfare and Coppice Woodland Restoration

The hazel dormouse is one of Britain most charismatic small mammals, spending half the year in hibernation and depending on ancient coppice woodland for food and nest sites, yet its population has declined by over 70% since 2000.

Key Facts

UK hazel dormouse numbers declined by around 72% between 2000 and 2020
They spend around seven months in hibernation, the longest of any British mammal
Dormice nest in dense woodland understorey and require a succession of flowering and fruiting plants through summer
Their welfare is closely linked to the health of ancient coppice woodland, which has declined due to management abandonment
People Trust for Endangered Species runs a national dormouse monitoring program using nest tubes

Welfare Considerations

Dormouse welfare depends on the availability of structurally diverse ancient woodland with a well-developed shrub layer providing food from hawthorn, honeysuckle, bramble, and hazel in succession. Abandonment of coppice management allowing canopy closure eliminates the shrub layer that dormice depend on. Poor hibernation body condition from insufficient autumn fat deposition causes mortality during prolonged cold winters. The species extreme sensitivity to disturbance means survey activities must follow strict protocols to avoid welfare harm.

What You Can Do

Support coppice woodland restoration programs through Hazel Dormouse Conservation Group and Wildlife Trusts
Advocate for agri-environment payments for traditional coppice management renewal
Contribute to People Trust for Endangered Species nest tube monitoring programs
Never disturb hibernating dormice found under logs or in nest boxes between October and April
Plant native woodland edge species including hazel, honeysuckle, and bramble in gardens adjacent to woodland
