  1. 1. Mängden död ved i värdekärnor i Söderåsens nationalpark

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Gustav Thurell; [2024]
    Nyckelord :volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

    Sammanfattning : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

  3. 2. A comparison of thinning programmes in European beech (Fagus sylvatica L.) based on permanent plots in Southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Delphine Anni Fortu; [2023]
    Nyckelord :beech; volume growth; diameter development; thinning programme; quality traits;

    Sammanfattning : The present study investigated 7 thinning experiments in beech which were established in 1971. The purpose was to compare two thinning programmes with different thinning intervals. The programmes (A and B) were designed according to yield tables by Carbonnier (1971). The experimental plots have been measured regularly in 5 to 10 years intervals. LÄS MER

  4. 3. Beech provenance trail in Sweden : growth and timber quality evaluation

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Lukás Vanícek; [2021]
    Nyckelord :Beech; climate change; growth; provenance; Sweden; timber quality;

    Sammanfattning : Provenance trails allow to test tree growth differences and meet current requirements for timber quality in a particular experimental site. The aim of this manuscript was to distinguish the differences in growth and timber quality features between European beech (Fagus sylvatica L. LÄS MER

  5. 4. Growth and timber quality evaluation of 33 European beech (Fagus sylvatica L.) provenances from a site in Southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :John Bergkvist; [2019]
    Nyckelord :trial; climate change; adaptation; growth; survival; Sweden;

    Sammanfattning : This study aims to shed more light on the differences in growth and timber quality characteristics between European beech provenances at its northern distribution margin. Data was collected from a provenance trial established in 1998 in southern Sweden to determine the growth and development of 33 provenances of European beech (Fagus sylvatica L. LÄS MER

  7. 5. Estimation of the potential BVOC emissions by the different tree species in Malmö

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Larissa Lisa Gesa Scholz; [2019]
    Nyckelord :BVOC emissions; isoprene; monoterpene; air quality; Malmö; Earth and Environmental Sciences;

    Sammanfattning : BVOC emissions from trees contribute to ozone and secondary aerosol formation and therefore have an impact on air quality. The two most abundant BVOCs emitted from trees are isoprene and monoterpenes. LÄS MER
