Sumario:Currently, most of the world’s forests are directly or indirectly affected by some kind of human activity. More people are getting concerned with the state of tropical forests. However, the international community has not tracked the rate and extent of ecological change in forests of the boreal zone, which is the largest biome in the world and comprise one-third of the world's forest area. Although European temperate forests were transformed centuries ago, there are still some large areas of forest in a relatively natural state left in boreal regions of Russia, Canada, Finland and Sweden. Five years ago, a team of Russian experts associated with non-governmental environmental organisations started to create new maps of Europe's last remaining wilderness forests, using high-resolution satellite images in combination with GIS, existing topographical maps and field work. The result of their effort, “The Last Intact Forest Landscapes of Northern European Russia”, was released by the World Resources Institute's Global Forest Watch (GFW) project and Greenpeace Russia in October 2001. The maps were created also for the rest of Russia and the “Atlas of Russia’s Intact Forest Landscapes” was released early in 2002. The project “Mapping of Intact Forest Landscapes in Sweden” was initiated by GFW in May 2002. The GFW Pan-Boreal Mapping Initiative originated as an idea to extend the unique Atlas of Russia’s Intact Forest Landscapes (Aksenov et al. 2002) over the World’s entire boreal zone. A number of non-governmental organizations and academic institutions in five countries (Russia, Finland, Sweden, Norway and Canada) were involved in creating a map of “Remaining Wildlands in the Northern Forests” as the first result of their cooperation. The map was presented as a poster at the Johannesburg Summit 2002 (26th August - 4th September 2002). This MSc thesis describes the background context of mapping undisturbed forests in Sweden, as well as the criteria and methods set by the initiating GFW project. Swedish forest conditions are partially covered in the Literature survey chapter, where the history of forest management and the natural characteristics of northern boreal forests are characterised. Previous works about mapping virgin forests in Sweden and related studies dealing with remotely sensed data are mentioned. The essence of the study focuses on the detailed description of the methodology (GIS in combination with the interpretation of satellite data) and the material used to create the map of intact forest landscapes in Sweden. Further, the comparison with other existing old-growth inventories can be found in the Discussion part, where also the significance of the output and the applicability of the Russian criteria to the Swedish vegetation conditions are evaluated.
