  1. 1. Can precommercial thinning be used to create more diversity after planting spruce?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Astrid Bygge; [2024]
    Keywords : Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Abstract : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. READ MORE

  3. 2. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity

    University essay from SLU/Dept. of Ecology

    Author : Hannah Sophie Jakob; [2023]
    Keywords : coarse woody debris; conservation; biodiversity; boreal forest; Daldinia loculata; Fennoscandia; prescribed burning; regeneration; wildfire; woodpecker;

    Abstract : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. READ MORE

  4. 3. Tree Species Impact on Forest Fire Spread Susceptibility in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sara Sharon Jones; [2023]
    Keywords : Geography; GIS; Physical Geography; Forest Fire; Forest Fire Susceptibility; Sweden; logistic regression modelling; Earth and Environmental Sciences;

    Abstract : Klimatförändringar förväntas leda till längre brandperioder och ökad brandrisk. I Sverige, där homogen produktionsskog utgör största delen av landskapet, finns ett behov av bättre förståelse för skogens mottaglighet för bränder för att kunna mildra risker. READ MORE

  5. 4. Scots pine for fika : the role of local moose density in determining browsing damages to pine across commercial forests in Sweden

    University essay from SLU/Dept. of Ecology

    Author : Rebecca Partemi; [2022]
    Keywords : moose; Scots pine; browsing damage; forestry; Äbin;

    Abstract : By browsing on young Scots pine (Pinus sylvestris), moose (Alces alces) can cause significant damage to commercial forests. The National Forest Agency monitors browsing damage and moose faecal pellet groups annually on pre-defined plots throughout Sweden. READ MORE

  6. 5. Evaluation of the forest composition in browsed Scots pine plantations

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Carl Noyce; [2022]
    Keywords : browsing damage; forest owners; mera tall; moose; pine regeneration; Södra;

    Abstract : Since the early 2000s browsing damage to Scots pine (Pinus Sylvestris) in the Götaland region of Sweden has been consistently estimated to be 15% per year, peaking at around 25% between 2009-2016, the highest of any region in the country. The Swedish Forest Agency has set a goal of achieving pine damage levels below 5% on average in the long-term, even if higher levels can be accepted in an individual year. READ MORE
