Torvmarkernas utveckling i östra Uppland

Sammanfattning: This report is about a couple of specially chosen peatlands in eastern Uppland, Sweden. It concerns their development between the year 1922 and 2012. The historic fact originates from a large investigation of peatlands in the south of Sweden made by the Swedish Geological Survey, SGU, in the 1920’s. To be able to choose peatlands an analysis in GIS were made, in which we were able to find locations good enough for our field investigation. During the field investigation we bore to find nice peat cores that later went through several analyses in a lab. The main goal with this investigation was to find out how much humans have been able to affect the peatlands and their development during the years, by for example agricultural activities. The conclusion we came to find was that agricultural activities have affected the peatlands in the form of composition.
