  1. 11. 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

  3. 12. Extended phenotypes in the canopies of Norway spruce

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Christofer Johansson; [2016]
    Keywords : extended phenotypes; Cinara spp.; Picea abies; associated organisms; C:N ratio; growth rate; aphid abundance;

    Abstract : The extended phenotype may help us understand how genetically determined trait variation in foundation species can influence associated organisms. Today, there is no existing demonstration of how genetically determined trait variation in Norway spruce (Picea abies) may affect associated organisms in tree canopies. READ MORE

  4. 13. Tree cover and tree traits affects soil carbon and soil compaction in parklands in central Burkina Faso

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

    Author : Gustaf Dal; [2016]
    Keywords : Burkina Faso; soil; soil organic carbon; dry bulk density; parklands; trees; agroforestry; vegetation density; tree density;

    Abstract : Burkina Faso is a country with an insufficient agricultural production and this is partly due to the fact that the population is growing and also because of environmental factors such as drought, erosion and poor soils. The most common agricultural system in this part of the world is the parkland which can be defined as farmlands with scattered well-grown trees. READ MORE

  5. 14. Regeneration dynamics of pedunculate oak in natural temperate forests: a case from southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Olle Finnström; [2016]
    Keywords : eutrophic temperate mixed broadleaf forest; competition; crown size; disturbance; oak regeneration; pedunculate oak; quercus robur; stem diameter; tree height;

    Abstract : Oaks are some of the most wide-spread and iconic trees in human culture, yet populations of oaks are declining due to land conversion, disease and because of lack of disturbance in temperate forests. Oaks are fairly light demanding trees, requiring large-scale disturbance to create suitable environments for regeneration. READ MORE

  6. 15. Olika röjningsprograms effekter på kvalitets och diameterutveckling i Bokskog

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Hampus Plantman; [2015]
    Keywords : röjning; Fagus sylvatica; kvalitet; volymutveckling; bokskog; pre-commercial thinning; European beech; quality development; volume production; stand development;

    Abstract : Boken är Sveriges näst viktigaste ädellövträd och ett utpräglat sekundärt trädslag som trivs bäst i sluttningar med god bonitet. För att uppnå en god virkesproduktion med en tillfredställande kvalitet har boken relativt höga ståndortskrav. Av boktimmer görs det huvudsakligen fanér, möbler och finsnickerier. READ MORE
