Wild Adder Conservation and Welfare UK

Adders are the UK's only venomous snake - they face severe population declines and need legal protection and habitat management.

Key Facts

Adder populations have declined by over 50% in recent decades with localised extinctions common
They require mosaics of open sunny areas for basking, dense vegetation for refuge, and suitable hibernation sites
Adders are legally protected under the Wildlife and Countryside Act 1981
Illegal killing remains a significant welfare threat despite legal protection
Dog bites from adders cause significant veterinary welfare concern - treatment requires antivenom
Climate change is affecting basking behaviour and phenology with uncertain welfare consequences

Welfare Considerations

Adder welfare requires both legal protection from deliberate killing and appropriate habitat management. Heathland scrub encroachment shades out basking areas eliminating adders even without persecution. Public attitudes toward adders remain negative in many areas, making education alongside management essential.
