Development of single oak trees in a mixed coniferous stand

摘要: Pedunculate oak (Quercus robur) and sessile petraea) are important tree species in the southern half of Sweden. Oak trees house a large biological fauna can have high value timber. Managing oaks pure stands is common but portion found admixed coniferous stands. The aim study was to investigate growth single multi-layered, conifer-dominated mixed stand relation thinning method, competing age. The conducted Tonnersjoheden experimental forest Sweden on 100-year old pine with naturally regenerated spruce oak. area divided into different target diameter harvest treatments thinned 2008-2009. 90 were sampled for analyses, 30 age analyses data from long-term used comparison. Results revealed that grew significantly more than control. difference between various not significant. Oaks higher number neighbouring Norway less few or no trees. Any effect distance size found. measured 38-68 years had positive DBH height. Due light demanding nature oak, essential sufficient suppressed How be this study. by neighbour noticed while neighbours not, implying focus (in case spruce) when promote growth.
