  3. 17. Fukthaltens inverkan på spridningshastigheten i gräsbränder

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Marcel Hermansson; [2017]
    Nyckelord :gräsbrand; naturvård; biologi;

    Sammanfattning : Detta examensarbete undersöker sambandet mellan fukthalt i gräsmarkers finmaterial och spridningshastighet i en brandfront, samt skillnaden mellan betade och obetade marker. Genom att mäta andra förhållanden som biomassa och medelvindhastighet kan även andra eventuella samband beräknas utöver fukthalten. LÄS MER

  5. 19. Auditiv berikning till lappuggla (Strix nebulosa) på Nordens Ark : att stimulera jaktbeteenden

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health
