  1. 1. Röjningsstrategiers effekt på stubbskottsutveckling och granmedelhöjd i blandbestånd av gran och björk

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Max Lindhe; Jonathan Samuelsson; [2023]
    Keywords : röjningsstrategi; stubbskott; björk; gran;

    Abstract : Olika röjningsstrategier förväntas påverka stubbskottsbildning hos röjstubbar av vårtbjörk (Betula Pendula Roth) och glasbjörk (Betula Pubescens Ehrh), men relativt få studier har gjorts på området, varför det finns utrymme för vidare forskning. Det huvudsakliga syftet med den här uppsatsen var att undersöka skillnaderna i stubbsskottsutveckling till följd av olika röjningsstrategier. READ MORE

  3. 2. Emergence patterns of Ips typographus and Medetera spp. after overwintering in killed spruce trees

    University essay from SLU/Dept. of Ecology

    Author : Oliver Morén James; [2023]
    Keywords : Ips typographus; Medetera; M. signaticornis; M. pinicola; M. ambigua; emergence patterns;

    Abstract : Ips typographus (Coleoptera: Curculionidae, Scolytinae) is a pest species that mainly attacks Norway spruce (Picea abies L. Karst.) and can kill large volumes of spruce trees during outbreaks, leading to economic losses of great magnitude. A common practice to manage attacks is to remove recently killed trees and thereby remove the beetles. READ MORE
