    Keywords : European ash; silviculture; Fraxinus excelsior; thinning; ash dieback; guidelines;

    Abstract : European ash Fraxinus excelsior L. is a large deciduous tree species common throughout Europe. It can grow on a wide range of sites and is often found in mixed broadleaved forests. Ash rarely occurs in pure stands, which probably explains why silviculture of the species has received little attention in the past. READ MORE

    Keywords : Fuel pellets; Extractives; CCF-design; MLR-regression; Pellet quality;

    Abstract : The use of renewable resources is rapidly increasing in Sweden, especially the use of fuel pellets. Through pelletizing the energy content per volume unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips.
