  1. 1. Planteringspunktens påverkan på plantöverlevnad

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Albin Lindberg; Oskar Lindström; [2023]
    Nyckelord :planteringspunkt; plantöverlevnad; vitalitet;

    Sammanfattning : Skogsvårdslagen har sedan 1903 satt krav på återväxt på avverkade skogsmarker. Skyddet för dessa plantor har historiskt gått från kemisk plantbehandling till mekaniskt skydd och olika former av markbehandling. LÄS MER

  3. 2. Efficiency of chemical and mechanical plant protection on sites without mechanical site preparation in Scania

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Gustav Nylander; [2021]
    Nyckelord :pesticide; mechanical protection; Pine Weevil; Hylobius abietis; Black spruce beetle; Hylastes conicularius; Strophosoma capitatum; No mechanical site preparation; Norway spruce; Picea abies; Regeneration; Seedlings; Hylonox; Imprid Skog; Forester; Woodcoat; wax;

    Sammanfattning : An important part of the regeneration after clearcutting is to have a high growth and a high level of survival of the planted seedlings. A big threat to the seedlings is the pine weevil (Hylobius abietis), but the black spruce beetle (Hylastes conicularius) can cause some serious damage too, as well as Strophosoma capitatumn. LÄS MER

  4. 3. Vilken granplanta bör användas vid föryngring? : en jämförelse mellan leverantörer, planttyper och plantskydd

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Patrik Oleinikoff; [2018]
    Nyckelord :plantförsök; borrotsplanta; snytbagge;

    Sammanfattning : The purpose of this study is to compare suppliers and variation of spruce seedlings that Linköpings Skogstjänst AB often uses in the rejuvenation phase. A trial plot has been laid out in the fields where seven different plants have been compared. A comparison has also been made between the bare root seedling and containerized seedlings. LÄS MER

  5. 4. Alternativa metoder till hägn för att minimera viltskador på hybridaspföryngringar

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

    Författare :Annette Eilert; [2017]
    Nyckelord :Hybrid aspen; herbivore damage; browsing; seedling protection; anthropogenic disturbance; fence;

    Sammanfattning : The purpose of the study was to find alternatives to fences by comparing the frequency of damages on different configurations of chemical treated, mechanically protected and untreated hybrid aspen seedlings, planted on agricultural land. The study also explored whether anthropogenic disturbance (proximity to roads and buildings) had any effect on the frequency of seedlings damages. LÄS MER

  7. 5. Tree establishment under high browsing pressure in Eriksberg Wildlife Park, Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Peteris Virs; [2017]
    Nyckelord :Browsing; ; ; seedling protection; forest regeneration; Eriksberg Wildlife Park;

    Sammanfattning : The aim of the study was to investigate under which conditions (in terms of topography, amount of rocks, presence of thorny bushes, visibility, etc.) temperate trees can establish under very high browsing pressure. The study was conducted in Eriksberg Wildlife Park (EWP), Blekinge, Sweden. LÄS MER
