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. Long-Term Results of a Field Experiment in Conifer Mixed Regenerations

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Hammed Abiola Adekunle; [2023]
   Keywords : regeneration; Drettinge method; Scots pine; Norway spruce; Clearcut; Shelterwood;

   Abstract : A national regeneration experiment was established across the boreal forest of Sweden. This study presents the regeneration results of the combination method, the so-called Drettinge method, which aims to evaluate the establishment of mixtures of naturally regenerated Scots pine (Pinus sylvestris L.) and planted Norway spruce (Picea abies L. Karst. READ MORE

5. 4. Mixed Stand vs Monoculture : a Simulation Study Assessing Growth and Profitability of Norway spruce and Birch in Mixtures and Pure Stands

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Babatunde Dosumu; [2022]
   Keywords : N.spruce-birch stands; monoculture; thinning treatment; mixed forest;

   Abstract : Picea abies L. Karst (N. spruce) monocultures dominate the forest landscape of southern Sweden due to their suitability for the prevalent site conditions, well established silviculture, and profitability. However, disturbances such as windthrow, bark beetle damage, and Heterobasidion root rot pose a risk to N. READ MORE

6. 5. Effects on natural seed regenerated Silver birch (Betula pendula Roth) and Downey birch (Betula pubescens Ehrh) by mechanical soil scarification and environmental factors : påverkan på naturligt fröföryngrad Glasbjörk (Betula pubescens Ehrh) och Hängbjörk (Betula pendula Roth) av mekanisk markberedning och omgivande faktorer

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Oskar Karlsson; [2022]
   Keywords : natural birch regeneration; Birch seed regeneration; soil scarification;

   Abstract : The awareness of forest biodiversity as well as the demand for a higher proportion of deciduous tree species in Swedish forests increases. As such, focus is shifting towards the management of naturally seed regenerated Silver birch (Betula pendula Roth) and Downey birch (Betula pubescens Ehrh). READ MORE
