Wild Grass Snake Welfare and Habitat

Grass snakes are the UK's largest native snake and depend on warm, moist habitats with access to water and basking sites.

Key Facts

Grass snakes are excellent swimmers and primarily prey on amphibians
They lay eggs in warm decomposing vegetation including compost heaps
Garden compost heaps are used as incubation sites in many UK gardens
Grass snakes are legally protected and must not be killed or disturbed
Habitat loss through drainage, development, and agricultural intensification has caused decline

Welfare Considerations

Grass snakes unable to find suitable basking and egg incubation sites in fragmented habitats cannot thermoregulate or reproduce effectively. Creating and retaining south-facing log and leaf piles and compost heaps in gardens directly supports grass snake welfare. Never destroying or disturbing compost heaps in summer protects incubating eggs.

What You Can Do

Create south-facing log piles and leave compost heaps undisturbed in summer
Create or maintain garden ponds to support amphibian prey for grass snakes
Report grass snake sightings to local wildlife trusts and reptile surveys
