1. 21. Determinants of winter browsing intensity on young Scots pine (Pinus sylvestris) by moose (Alces alces) across a bio-geographical gradient in Sweden

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

   Författare :Lenka Vysinova; [2010]
   Nyckelord :moose; Alces alces; browsing; Scots pine; Pinus sylvestris; spatial scale; determinants; forage cover; tree species composition;

   Sammanfattning : Intensive moose (Alces alces) browsing pressure has a large impact on ecosystems as well as economics of forestry companies. Moose winter browsing pressure on young Scots pine (Pinus sylvestris) is affected by a range of factors and I modelled effects of such factors across a bio-geographical gradient in Sweden. LÄS MER

3. 22. Forage production and summer use by ungulates on game fields and surrounding areas

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

   Författare :Lovisa Nilsson; [2009]
   Nyckelord :browsing; damage; game fields; forage availability; ungulates;

   Sammanfattning : Ungulates are causing conflicts between stakeholders due to browsing damage on forests and agricultural crops. At the same time there is a big demand of keeping high ungulate densities for sports hunting and recreational purposes. Movement patterns of ungulates are strongly correlated with forage availability. LÄS MER

4. 23. Herbivory on woody plants and induced responses in two similar species of Acacia in the Kruger National Park, South Africa

   L3-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Fredrik Engdahl; [2008]
   Nyckelord :large herbivores; savanna system; Kruger national park; tree responses;

   Sammanfattning : I studied browsing patterns and the effects of browsing by different groups of herbivores on woody plants in Kruger National Park in South Africa. I determined how the browsing pressure varied with distance to water and measured inducible responses on two species of Acacia (A. exuvialis and A. grandicornuta). LÄS MER

5. 24. Jämförelse mellan maskinell markberedning/plantering med EcoPlanter och manuell plantering efter konventionell harvning : etablering och tillväxt i tall- och granbestånd 7-9 år efter plantering i Östergötland

   L3-uppsats, SLU/Dept. of Silviculture

   Författare :Pär-Ragnar Frank; [2006]
   Nyckelord :mekaniserad skogsföryngring; södra Sverige; barrträd; etablerad ungskog;

   Sammanfattning : I skogsbruket ställs ständigt krav på effektiviseringar och ökad tillväxt. Samtidigt efterfrågas, via certifieringskrav, lagändringar och opinionsyttringar, ett skonsammare skogsbruk med ökad miljömedvetenhet och ett mer hållbart nyttjande av skogen som resurs. LÄS MER
