Wild Hedgehog Hibernation Welfare and Winter Preparation

Hedgehog hibernation is a critical welfare period. Disturbance of hibernating hedgehogs and inadequate fat reserves are significant causes of winter mortality.

Key Facts

Hedgehogs typically hibernate from November to March in the UK
They need to weigh 600g or more to survive winter hibernation
Juvenile hedgehogs born late in the year may be underweight and vulnerable
Disturbing a hibernating hedgehog can be fatal - it loses critical energy reserves

Welfare Considerations

Never disturb potential hibernation sites between November and March. Underweight hedgehogs found in autumn can be overwintered by wildlife rehabilitators to ensure they enter spring at a healthy weight.

What You Can Do

Check bonfires before lighting for hibernating hedgehogs
Leave areas of dead leaves and log piles undisturbed through winter
