Grass Snake Welfare in Gardens and Wetlands

The grass snake is Britain largest native snake and is associated with garden compost heaps, ponds, and wetlands, but has declined due to habitat loss and tidying up of rough ground.

Key Facts

Largest native British snake reaching up to 150cm
Lays eggs in warm decaying vegetation including garden compost heaps
Feeds almost exclusively on amphibians and fish
Fully protected under the Wildlife and Countryside Act
Has declined significantly with loss of rough ground and compost heaps

Welfare Considerations

Grass snake welfare is affected by loss of egg-laying sites as compost heaps are replaced with hot composters, garden tidying removes rough ground, and amphibian prey declines. Maintaining traditional compost heaps and garden ponds provides significant welfare and conservation benefit.

What You Can Do

Maintain a traditional open compost heap as a potential egg-laying site
Create wildlife ponds to support amphibian prey populations
Leave rough grass and log piles as habitat
Report grass snake sightings to ARG UK monitoring
Never handle wild snakes unnecessarily as it causes significant stress
