Hazel Dormouse Welfare: Woodland Management in the UK

The hazel dormouse is a protected British mammal declining across its range due to woodland fragmentation and the loss of traditional coppice management that creates the dense shrub layer it requires.

Key Facts

Hazel dormice have declined by around 51% in the UK over the past 20 years
They depend on interconnected woodland with a rich shrub layer providing berries, nuts and flowers
Dormice spend around half the year in hibernation, making them vulnerable to weather disruptions
Licensed nest box schemes help monitor populations and provide additional nesting sites

Welfare Considerations

Loss of traditional coppice and hazel scrub management has reduced the dense shrub layer dormice require for foraging and nesting. Woodland fragmentation isolates populations preventing genetic exchange. Climate change causing mild wet winters can disrupt hibernation, leading to energy depletion and death. Dormice disturbed during hibernation lose critical energy reserves.

What You Can Do

Support woodland management organisations restoring hazel coppice across southern England
Participate in licensed dormouse nest box monitoring schemes through local wildlife trusts
Never disturb hibernating dormice even if found during woodland work
Donate to People's Trust for Endangered Species working on dormouse recovery
