Adder Vipera berus

This enigmatic snake typically displays the vibrant zig-zag dorsal pattern along the length of its body, though the patterning is variable. It hibernates during the winter; when active during warmer months, it can be seen basking and foraging. Despite being a protected species, the number and range of adders continues to slowly decline.

Conservation status

Adders have a widespread distribution within Britain. They are scarce across much of East Anglia, but there are strongholds that exist along coasts and heaths. Heathland habitat has declined in Norfolk and it is likely that with the loss of this habitat adders have also declined in numbers and range.
