Skötsel av ekblandskogar: naturvårdsgallring och respons hos träd och buskar Management of oak-rich mixed forests: conservation- oriented thinning and response of trees and shrubs

摘要: During the last century Swedish forestry has intensified with large-scale forest plantations, especially Norway spruce (Picea abies), and use of clearcutting, which have influenced biodiversity negatively. Efforts to conserve include legal protection voluntary set-asides, mainly managed through minimal intervention (passive management). Oaks (Quercus spp.) formerly grew a large extent in open habitats, such as woodland pastures. Abandonment pastures led many closed-canopy mixed forests. Conservation-oriented thinning is type active management, aim favour oaks robur / Q. petraea) associated species. In this thesis, I investigate whether how conservation-oriented favoured oak regeneration, also examine effects on other woody species, comparison factors, 25 oak-rich forests southern
