Wild Hedgehog Hibernation and Winter Welfare

Hedgehog hibernation is a critical survival strategy in the UK, and both weather patterns and food availability before hibernation determine individual welfare outcomes.

Key Facts

Hedgehogs should weigh at least 600g before hibernation to survive the winter
Juveniles born late in the season may not reach hibernation weight, requiring intervention
Hibernation can be interrupted by warm winter spells, using vital fat reserves
Hibernating hedgehogs should not be disturbed as arousal costs significant energy
Log piles and purpose-built hibernation boxes provide safe overwintering habitat

Welfare Considerations

Hedgehogs that enter hibernation underweight face starvation before spring. Late juveniles and those in poor body condition require targeted intervention including supplementary feeding and potentially overwintering in care to survive and contribute to population recovery.

What You Can Do

Leave log piles and leaf litter as hedgehog hibernation habitat
Supplement hedgehog feeding in autumn to support hibernation weight
Check bonfires for hibernating hedgehogs before lighting
Contact a local hedgehog rescue if you find a small hedgehog active in November or later
