  1. 1. Ekoparkernas inverkan på långhornskalbaggar (Cerambycidae) : artrikedom, abundans och artsamhällen i jämförelse med kommersiellt brukad skogsmark

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Elias Skogqvist; Emil Andersson; [2022]
    Nyckelord :naturvård; aktiv restaurering; död ved; substrat; rödlista; unika arter;

    Sammanfattning : Several dead wood-dependent beetles need substrates which to great extent have been disfavored by intense forestry. Active and continuous restoration in Ecoparks may offer an option with intention to improve the habitation conditions. LÄS MER

  3. 2. Diversity patterns and composition of wild bee communities (Hymenoptera: Anthophila) in Swedish boreal forests under different management regimes

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Jaime Ramón Luna Santa-María; [2021]
    Nyckelord :wild bees; Anthophila; forest management; functional diversity; landscape ecology; inventory diversity; boreal forest;

    Sammanfattning : Intensive forest management has led to forest homogenization with associated changes to biodiversity. Compensatory actions have been taken to counteract the negative effects of these practices on biodiversity, but the effectiveness of these actions depends both on which scale they are evaluated and the group of species they are addressed to.

  4. 3. Effects of active and passive conservation on forest structure and bird diversity in Färna Ecopark

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Arvid Sandström; [2021]
    Nyckelord :biodiversity; deciduous forest; avifauna;

    Sammanfattning : Voluntary set-asides are an important part of the conservation of forest species in Sweden. Set aside stands are either treated passively by leaving them untouched (in Swedish abbreviated as NO) or with active, often invasive maintenance (NS). LÄS MER

  5. 4. Från lövsanering till björkens ekopark : den historiska användningen av herbicider inom ekopark Käringberget

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Sandra Pettersson; Petter Rönneland; [2019]
    Nyckelord :herbicider; ekopark; fenoxisyror; flygbesprutning; skogshistoria; lövträd;

    Sammanfattning : I början av 1940-talet utvecklades en ny typ av effektiva ogräsdödande kemikalier, så kallade hormonderivat. Dessa hormonderivat, som är en typ av herbicider kom att användes för att bekämpa lövvegetation inom skogsbruket i Sverige. LÄS MER

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

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

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

    Sammanfattning : 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.
