Saving England's most threatened species from extinction

Adder

The Adder is one of our three native species of snake and our most widespread, being found from the south of England to the north of Scotland.

However, populations in central Britain are in decline. The Adder is easily recognised by a dark, continuous 'zig-zag' stripe along its back. The background colour varies from grey-white in the male to shades of brown or copper in the female. Young Adders are copper, light brown or reddish, with darker brown markings. Adders can grow to around 60cm in length and have rather a stocky appearance.
