  1. 1. Thinning strategies of birch in Latvia, with application in a newly established field experiment

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Dagnija Saicane; [2019]
    Keywords : silver birch; abandoned agriculture land; thinning; pruning; design;

    Abstract : Birch (Betula pendula Roth) is an early successional species which, if grown in suitable soils with wise management, can have high and valuable production. Large-dimension birch-wood is used for saw logs and plywood production, but smaller ones for pulpwood and energy wood. READ MORE

  2. 2. Restoration of mixed forest : effects of fencing, site preparation and distance to existing mixed forest on planted European beech and natural tree regeneration

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Mateusz Szydło; [2017]
    Keywords : European beech; fencing; mixed forest restoration; mechanical site preparation; Scots pine; Raslången ecopark;

    Abstract : During restoration of mixed forest from mono-specific spruce forest there is a great need for knowledge of the extent to which proximity to other mixed forest affects regeneration results and diversity of tree and shrub layers. There is also lack of knowledge of what fencing means for the regeneration of individual species, as well as how mechanical site preparation (MSP) influences both planted and naturally regenerated plants.

  3. 3. Forest succession on abandoned agricultural land and its carbon stock

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Parisa Mazinanian; [2017]
    Keywords : forest succession; carbon stock; tree species; understorey vegetation; agricultural land abandonment; biomass; secondary forest; old-growth forest; soil carbon; carbon sequestration;

    Abstract : The development of secondary forest on abandoned agricultural lands has proven significant to land cover changes, especially in marginal areas across Europe. It is therefore important to quantify secondary forest succession in order to sustainably manage forest and agricultural resources, and also for modelling climate change. READ MORE

  4. 4. Degradation and restoration method interact to affect the performance of planted seedlings in tropical rainforest restoration : evidence from plant functional traits

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

    Author : Julia Mellåker; [2016]
    Keywords : Dipterocarpaceae; enrichment planting; INIKEA; secondary rainforest; hjälpplantering; sekundär regnskog;

    Abstract : A common action to improve or save biodiversity in the tropics is restoration of degraded rainforest. To understand the complex ecological structures of the forest and adapt the restoration actions after them, studies have focused on characterizing species with functional traits. READ MORE

  5. 5. Natural regeneration on clear cuts in Southern Sweden : how fencing, soil treatment and distance from broad-leaved forest affect tree regeneration and ground vegetation

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Jón Ásgeir Jónsson; [2016]
    Keywords : natural regeneration; forest restoration; pioneers; noble broadleaves; Picea abies; soil scarification; fencing; distance from broad-leaved forest; Raslångens ekopark;

    Abstract : The forests of Europe have seen a dramatic shift in structure, species composition and area coverage in the last centuries. Large areas previously covered by a mixed broad-leaved forest are now used for agriculture or other land uses. READ MORE
