21. The importance of forest forage resources and a landscape perspective, managing bumblebees (Bombus) in Swedish forest-farmland
Master-uppsats, Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)Sammanfattning : The Swedish forest has been transformed during the last hundred years, from semi-open forest of multiple tree species to dense production forest of mainly spruce and pine. This has led to alterations of species composition in the forest floor, reducing coverage of dwarf shrubs like Vaccinium myrtillus (European blueberry). LÄS MER
22. Peatland restoration: A mossy affair? : The similarities of the vegetation communitiesbetween restored bogs and natural bogs.
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Peatlands function as important global carbon sinks as peatlands store 30% to 40% of the total soil carbon even though peatlands only cover 3% of the Earth's terrestrial surface. However, drainage activities have damaged the ecosystem and caused many peatlands to function as carbon sources instead. LÄS MER
23. Go with the flow - can environmental flows save us? : A study of the flow patterns in Bredforsen and possibilities for the future
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Freshwater systems have, during human history, endured large-scale impacts. According to the water framework directive, measures must be developed to create a better environment for species in, and connected to, freshwater systems. Hydropower plants has caused loss of natural disturbance (e.g. LÄS MER

25. Could horse grazing be used to restore abandoned fields? : a comparison of the vegetation between horse pastures and abandoned fields, and an inventory of the effects of grazing- history and intensity
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Semi-natural fields, created by traditional land-use systems like low-intensity cattle grazing, have high ecological value due to the occurrence of numerous plant species, and their associated faunal communities. In Sweden, this habitat is threatened by both land-abandonment and agricultural intensification. LÄS MER
