  1. 6. Browsing behaviour in complex ungulate multi-species systems in Southern Sweden

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Jonatan Sandberg; [2019]
    Nyckelord :browsing pressure; interspecific competition; multi-species;

    Sammanfattning : In recent years several of the ungulate species present in Sweden have increased in both densities and distribution. Browsing pressure has mainly been attributed to moose but recent research shows that with more complex ungulate ecosystems new interactions and connections might emerge. LÄS MER

  3. 7. Ny metod för behandling med viltskydd på skogsplantor

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Victor Ljungar; Linnea Ottosson; [2018]
    Nyckelord :Wildlife; moose; browsing; biodiversity; pine; browsingprotection; forestry; viltbete; viltbetesskador; biologisk mångfald; Tall; Trico viltskydd; RASE.;

    Sammanfattning : A threat is that some of the tree species that are important for the biodiversity are under a lot of pressure because of the high browsing activity. The Swedish forestry agency has now together with the forest industry set an acceptable level of browsing on production forest that 70% must be non-browsed when the stands are 5 meters or higher.

  4. 8. Have wolves (Canis lupus) finally scared moose (Alces alces) in Sweden?

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Mark Jamieson; [2018]
    Nyckelord :landscapes of fear; predator-prey interactions; habitat selection; resource selection functions; ecology;

    Sammanfattning : Carnivores are coming back to Europe and the repercussions of their return on prey species is not fully understood. Research from North American studies suggests predators can indirectly affect how ungulates will select their habitat which can result in a change in vegetation growth as browsing pressure is relaxed in risky areas.

  5. 9. Timing of ungulate browsing and its effect on sapling height and the field layer vegetation : experimental study using seasonel exclosures during one year

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Filip Ånöstam; [2017]
    Nyckelord :clear-cut; ungulates; browsing; saplings;

    Sammanfattning : Browsing and grazing by ungulates affect the forest structure by altering species composition and affect the growth in individual trees. The purpose with this study is to investigate the ungulate species composition visiting the clear cut, how timing of browsing affects the height increment in deciduous and conifer saplings, and how deer grazing affects the field layer coverage and height.

  7. 10. Tree establishment under high browsing pressure in Eriksberg Wildlife Park, Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Peteris Virs; [2017]
    Nyckelord :Browsing; ; ; seedling protection; forest regeneration; Eriksberg Wildlife Park;

    Sammanfattning : The aim of the study was to investigate under which conditions (in terms of topography, amount of rocks, presence of thorny bushes, visibility, etc.) temperate trees can establish under very high browsing pressure. The study was conducted in Eriksberg Wildlife Park (EWP), Blekinge, Sweden. LÄS MER
