NatureScot Commissioned Report 520: Expansion zone survey of pine marten (Martes martes) distribution in Scotland 2012
This study investigates the changing distribution of the pine marten. The survey focused on an ‘Expansion Zone’ mainly to the east and south of the marten’s previously known range (based on the last survey in the 1990s) and included eastern Caithness, Moray, Aberdeenshire, Angus, much of Argyll, Perth & Kinross, Stirlingshire and the Trossachs, Fife and Dumfries & Galloway. The method involved experienced teams searching for pine marten scats (faeces) along 1km transects during May to August. Molecular techniques were used to extract DNA from scats to confirm their species of origin. The findings confirm that the species continues to recolonise its former range and now occurs close to some of Scotland's major urban areas.
