Wild Adder: Habitat Conservation and Human Conflict

The adder, Britain's only venomous snake, faces serious population decline from habitat loss and deliberate killing, despite being legally protected and posing minimal risk to humans.

Key Facts

Adder populations have declined by up to 90% at some sites over the past 30 years
Adders are legally protected under the Wildlife and Countryside Act - killing or disturbing them is illegal
Most adder bites in the UK occur when people or dogs accidentally tread on them
Adders are reclusive and will always attempt to escape rather than attack when given the opportunity
Heathland fragmentation isolates adder populations, reducing genetic diversity and recolonisation capacity
Controlled burns on heathland management can benefit adder habitat when carried out appropriately

Welfare Considerations

Adder welfare is compromised primarily by deliberate persecution from people who fear them, and by habitat fragmentation that creates small isolated populations vulnerable to disease and genetic bottlenecks. Adders found on paths or in gardens are frequently killed despite legal protection. Injured adders from vehicle strike or dog attack require specialist reptile veterinary care. The decline of adder populations represents individual suffering through habitat loss and persecution that is preventable through better public education and habitat management. Adder conservation is a welfare issue as much as a biodiversity one.

What You Can Do

Never attempt to kill or handle an adder - they are legally protected and will not attack unprovoked
Report adder sightings to local wildlife recording groups to contribute to population monitoring
Keep dogs on leads in known adder habitat during spring and early summer
Seek immediate veterinary care for dogs bitten by adders
Support heathland conservation management that maintains and connects adder habitat patches
