1. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing
Master-uppsats, SLU/Dept. of EcologySammanfattning : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

2. The effects of management practices and environmental variables on the biodiversity of Nardus grasslands in the national park Hohe Tauern, Austria
Master-uppsats, SLU/Dept. of EcologySammanfattning : Introduction. A large part of the biodiversity of the Alps is linked to an interaction between the natural environment and traditional land-use practices. This study focuses on the priority habitat type of species rich Nardus grasslands (Natura 2000 Code 6230*), which is endangered, but continues to thrive in extensively managed subalpine pastures.

3. Long term restoration effects : Effects of restoration measures on restoration success in nature reserves in acidic fen, buffered fen, dry heather, wet heather, and wet grassland in Drenthe, Netherlands
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Habitat degradation, fragmentation and loss are important factors causing loss in biodiversity and red listed species, and restoring habitats is essential in preventing this. However, there is a limited knowledge of the long term effects of restoration measures. LÄS MER
4. Floristic change in the province of Scania in southernmost Sweden 1800-2020: using fragmented data to study landscape-level shifts
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : Vascular plant observances were compiled for 10 well-documented parishes throughout southernmost Sweden from published floras, herbarium specimens, modern inventories, and a large citizen-science database to provide presence/absence of species from 1800-2020 at the decade level. A regionally-specific database of species-specific plant traits and ecological indicator values was used to examine floristic and ecological changes across an extended timeline which indicates that several of the most apparent conservation issues including climate warming, woody encroachment, and soil chemistry alterations have acted for long over a century.

5. How former arable fields with permanent grazing differ from managed semi-natural pastures in Sweden
Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : New farming needs and innovations have, over time, led to changes in land use. Arable fields have been turned into pastures and semi-natural pastures into arable fields. LÄS MER
