    Nyckelord :pasture restoration; biodiversity; species richness; effective number of species; plants; plant species; number of species; clearing; pasture; betesrestaurering; biologisk mångfald; artrikedom; effektivt artantal; växter; växtarter; antal arter; artantal; hävd; betesmark; naturbetesmark;

    Sammanfattning : Abstract Pasture is a very species-rich but threatened nature type, and compared to 200 years ago, only five percent of natural pastures remain in Sweden. One way to try to save the biological diversity that pastures harbor is to restore overgrown land by clearing and reintroducing grazing animals. LÄS MER

  3. 2. How does grazing and burning affect the occurrence and development of vascular plants?

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Felicia Ivarsson; [2023-02-17]
    Nyckelord :Keywords: burning; grazing; plot; restoration; plant; flower;

    Sammanfattning : Grazing and burning are disturbances that can be used for management of landscapes that are in need of restoration. When applying these disturbances, you can create a more diverse flora and fauna and control the grazing pressure from domestic cattle. LÄS MER

  4. 3. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför Lund

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Erik Borgström; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER

  5. 4. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Marta Holmlund; [2023]
    Nyckelord :wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

    Sammanfattning : 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.

  7. 5. Effekten på artsammansättning i växtsamhällen vid betning av Rangifer tarandus

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emilie Voss-Schrader; [2023]
    Nyckelord :grazing pressure; Rangifer tarandus; species composition; vegetation analysis; Malla Strict Nature Reserve;

    Sammanfattning : The fact that large herbivores, such as Rangifer tarandus, play a part in shaping its environment through grazing and trampling of the ground is widely acknowledged today, as well as that these factors have the potential of affecting regional patterns and even global climate. This study investigated whether a considerable increase in grazing by R. LÄS MER
