  1. 16. Faktorer som bidragit till nyetablering av ädellövskog i Dalsland

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Adrian Andersson; [2023]
    Nyckelord :Broadleaf forest; tempered deciduous forest; Noble deciduous trees; Ädellövskog; Ädla lövträd; Ädellöv; Ädellövskogsbruk;

    Sammanfattning : Sett över hela landet växer ädellövskog endast på en procent av den produktiva skogsmarken. I det studerade området Dalsland utgörs virkesförrådet uppskattningsvis av tre procent ädla lövträd. Dess förekomst är därför att betrakta som relativt sällsynt. LÄS MER

  3. 17. Recent expansion of the endangered beetle Plagionotus detritus in the greater Stockholm area

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Elin Lönnberg; [2023]
    Nyckelord :;

    Sammanfattning : Biodiversity is declining worldwide, and the biggest reason for this is habitat destruction. In Sweden one third of all the red listed species belongs in broadleaved deciduous forests. The  most common reason for the endangerment of these species is the destruction of the deciduous forest.

    Sammanfattning : The raccoon (Procyon lotor) has been a part of German fauna since the 1920s, following a number of releases and escapes from captivity. This study intends to investigate the distribution and activity patterns of this non-native mesopredator in Hainich National Park, which lies in Central Germany, in-between 3 core areas of established raccoon populations.

More than 500 men were employed for the canal construction and it took them 10 years to connect a waterway between the two large lakes. LÄS MER

  7. 20. How hot are retention patches as structural hotspots? : comparing key elements for biodiversity in retention patches and reference forest stands

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

    Författare :Maja Östlund; [2022]
    Nyckelord :retention forestry; retention patches; deadwood; live conservation trees; retention forestry; biodiversity preservation; substrate diversity;

    Sammanfattning : Sweden’s historical and current forestry regime has created structurally simplified forest stands with little resemblance of boreal old-growth forests, leading to a decline in many forest dwelling species. Retention forestry was introduced to counteract the negative development by retaining biologically important forest elements. LÄS MER
