  1. 6. 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. 7. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity
