Changes in the distributions of Red and Grey Squirrels in Scotland

Changes in the distribution of Red and Grey Squirrels in Forestry Commission land were examined using a replacement index for the period of 1980–94. Data from each administrative region in Scotland were examined separately. No region was found to have experienced a significant replacement of Red Squirrels by Grey Squirrels. However, significant trends in the area occupied by one or both Squirrel species were observed in the Borders and Strathclyde. Other areas appear to have experienced little or inconsistent changes in the last 15 years.
