The pine marten has a wide distribution in the Palaearctic, being found throughout most of Europe, Asia Minor, northern Iraq and Iran, the Caucasus, and in westernmost parts of Asian Russia (Western Siberia). It is widespread in continental Europe, with the exception of most of Iberia and Greece, and parts of Belgium and the Netherlands. It is found on the Mediterranean islands of Corsica, Sardinia, and Sicily. It was introduced historically to the Balearics (S. Roy pers. comm.). It was formerly widespread in the British Isles, but is now restricted to northern Britain and Ireland, where it is still common (S. Roy pers. comm.). Altitude ranges from sea-level to the timber line (2,300 m in the Pyrenees).
