Evidence from a new report raises concerns about the status of adders in Scotland.

The latest Scottish Adder Survey found that the reported distribution of Britain’s only venomous snake shrank significantly in Scotland between 1994 and 2024.

It found that the number of ten-kilometre squares in which adders have been reported in Scotland has substantially declined, from 567 pre-1994 to 364 from 1994 onwards – a 36% decrease.
