  1. 1. Evaluating thinning practices and assessment methods for improved management in coniferous production forests in southern Sweden

    Författare :Magnus Persson; Johan Bergh; Lauri Mehtätalo; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; thinning; within-stand variation; tree species classification; Scots pine; Norway spruce; Sentinel-2; Heureka; Precision forestry; thinning detection; basal area; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Most of our knowledge about wood production of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) and associated silvicultural guidelines are based on field experiments. LÄS MER

  3. 2. Regeneration methods and long-term production for Scots pine on medium fertile and fertile sites

    Författare :Mikolaj Lula; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Tree species choice is a central issue for forest management, and survey studies show that urgent improvements in regeneration practices are needed in Sweden. Most Swedish forest is regenerated with Scots pine (Pinus sylvestris L.) or Norway spruce (Picea abies (L.) H. LÄS MER

  4. 3. Impacts of climate change on forest management and implications for Swedish forestry : an analysis based on growth and yield models

    Författare :Narayanan Subramanian; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : While climate change is expected to increase the growth rates of most tree species in Sweden in the future, during this period, there are also increased risks of tree damage due to various risk factors associated with climate change. Therefore, it is necessary to develop adaptive management measures in order to exploit the benefits of climate change and minimize the damage resulting from these risk factors. LÄS MER

  5. 4. Individual-tree-selection in uneven-sized Norway spruce stands in southern Sweden : Developments of tools for simulation and optimization

    Författare :Nils Fagerberg; Johan Bergh; Peter Lohmander; Stergios Adamopoulos; Hubert Hasenauer; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; continuous cover forestry; selective cutting; Picea abies; uneven-aged; single-tree-selection; growth model; knot size model; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Individual-tree-selection (ITS) is a continuous cover forestry method that aims to utilize the uneven-sized stand structure through optimized individual tree selections. ITS is an interesting management alternative to rotation forestry in terms of production of multiple benefits and forest owner profitability. LÄS MER

  7. 5. Forest planning utilizing high spatial resolution data

    Författare :Pär Wilhelmsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis presents planning approaches adapted for high spatial resolution data from remote sensing and evaluate whether such approaches can enhance the provision of ecosystem services from forests. The presented methods are compared with conventional, stand-level methods. LÄS MER
