Distribution Map from YOUR records of adders
Each button or rectangle represents a 0.1 degree Latitude by 0.1 degree Longitude area within which you have reported at least one, but possibly more, snakes or slow-worms.

This lack of detail is intentional to prevent sites from damage and animals from persecution.

 Additionally at this stage none of these records have been verified.
