Wild Common Lizard and Climate Warming

Climate warming is affecting common lizard distribution and behaviour. Warmer springs enable earlier emergence and additional reproductive cycles, but extreme heat events create welfare risks.

Key Facts

Common lizards are ectotherms that regulate body temperature by moving between warm and cool microhabitats
Earlier spring warming allows common lizards to emerge from hibernation sooner
Extreme heat events cause lizards to retreat to shade, reducing foraging time and food intake
Climate warming may enable common lizards to expand their range northward in the UK
Habitat structural diversity becomes more critical in warmer climates as thermal refugia are needed

Welfare Considerations

Climate change creates both opportunities and challenges for common lizard welfare. Structural habitat diversity that provides thermal refugia alongside basking sites becomes increasingly important as temperatures rise.

What You Can Do

Create structurally diverse garden habitats including both warm and cool microhabitats for lizards
Record common lizard emergence dates as a contribution to climate impact monitoring
Support heathland and grassland restoration projects that maintain lizard habitat diversity
