Fig. 3. Land cover in River Helge å catchment within a buffer of 1000 m extending from the Helge å River main flow. A comparison between a composite of maps from 1865 to 1869 (Topographical Corp of the Swedish Armed Forces) and data from 2000 based on classified satellite images (Kontinuerlig Naturtypskartering av Skyddad Natur [KNAS] project, Swedish EPA, unpublished data). Data show an increase of total forest cover and an increase in coniferous forest cover (km²).
