Fig. 1From: Increasing loss of mature boreal forests around protected areas with red-listed forest speciesThe study area, Finland, and the three boreal forest vegetation zones. The background of the map shows the amount of forest habitat (from CORINE 2000 database) visualised using a 1 km moving window, and the agglomerations of the red-listed forest species occurrences in the current protected area network overlaid on the background map with a 10 km kernel density heat mapBack to article page
