NARRS - Adder Surveys

Adders are one of the "widespread" UK species we are most concerned about. The species was found in just 7% of reptile surveys in the first three years of NARRS - see the report here . NARRS widespread reptile surveys will help us monitor changes in distribution and occupancy rate for the adder in the UK, but we think more research is needed to help us target efforts for their conservation.

To report adders you've seen or places where you used to see adders, visit our Add an Adder survey page. Both historic and contemporary information will help us examine what has changed for adders in recent years.

If you'd like to get involved in regular monitoring of adder populations, consider taking part in Make the Adder Count. This project aims to provide data with which to monitor population trends and to strengthen the case for better conservation and protection. If you regularly see adders after their springtime emergence, you could help provide this important information.
