In recent years the sika has extended its range, especially in Scotland. The distribution map shows how it is now well established from Argyll up to the Great Glen and again north from Inverness to Sutherland. Another colony in Peebles is now expanding northward and eastward. In England sika are to be found in Lancashire and Yorkshire, southern Dorset and the New Forest. In addition, small local populations exist in the vicinity of several of the parks from which they originally escaped.
