Grass Snake Welfare in Gardens

Grass snakes are the UK's largest native snake and visit gardens to hunt amphibians, bask and lay eggs in warm composting material, providing an important link in garden food chains.

Key Facts

Grass snakes lay eggs in compost heaps and rotting vegetation where temperatures are stable
They are harmless to humans and primarily hunt frogs, toads and newts
UK populations have declined significantly due to habitat loss and mortality on roads
Compost heaps and log piles provide critical nesting and hibernation sites

Welfare Considerations

Grass snake welfare in the UK is compromised by fragmentation of habitat between suitable breeding sites, hibernation areas and hunting grounds. Garden features such as compost heaps represent some of the last remaining suitable egg-laying sites in some suburban areas. Persecution by humans who fear snakes remains a welfare risk.

What You Can Do

Maintain a traditional compost heap to provide egg-laying sites for grass snakes
Do not disturb or relocate a grass snake found in the garden — they are harmless
Avoid using strimers in long grass during May-July when snakes may be sheltering
Report grass snake sightings to the Amphibian and Reptile Conservation Trust
