  3. 2. Are large clearcuts the only way to manage forests? : a study of economic performance and deadwood production of various silviculture systems

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Haidi Andersson; [2023]
    Nyckelord :uneven-aged forestry; continuous cover forestry; CCF; clearcut; deadwood; RFM; even-aged forest; Net present value; Heureka;
