    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
