Here, we give a brief overview of the current knowledge of tree species mixing effects on growth at the stand, species, and tree level. Main causes of the tree species mixing effects Overyielding of mixed versus mono-specific stands results mainly...
The study of past landscapes and ecosystems is known as paleoecology, which is closely related to geology, biology and botany, as well as history and archaeology. The unique benefit of paleoecology as compared to neo-ecology is the time perspective, as...
With increased awareness of wood production for bioenergy, high-productive mixed stands become more relevant for forestry where high growth rate, high carbon sequestration and resilience are combined with other important goals. For example, two-storied mixed plantations combining late successional and...
– Mixed-species forests can fulfil many forest functions and services better than mono-specific stands and receive growing attention in forest science and practice. Hans Pretzsch, professor at the Technical University of Munich has his expertise in silviculture and has worked...
One aim of the Ph.D project is to gather the overall existing information on the differences between and within the different provenances of subalpine fir (Abies lasiocarpa) with regards to mortality, growth, tree properties, resistance to aphids and fungi, post-harvest...
NordGen Forest policy brief: Is Nordic forestry prepared for climate change? Climate change is recognised as one of the most important challenges for both society and many ecosystems. Although forest ecosystems are generally robust, there is a concern that the...
The Nordic cooperation aims for carbon neutrality within the energy sector by 2015. – This goal is difficult to reach if one does not include forest biomass to a greater degree, with foreign tree species playing an important part when...
Text: Ditte C. Olrik, Ministry of Environment and Food of Denmark, Nature Agency Ash dieback disease is characterised by necrosis in the bark and basal part of the stem, as well as leaf loss, formation of epicormic shoots and crown dieback....
Text: Juho Hautsalo, Natural Resources Institute Finland (Luke) Finnish pedunculate oak (Quercus robur) populations are very small, isolated and when compared to Central European oak populations they have higher genetic diversification rate and lower diversity. This is typical for populations...
Text: Kari Leinonen (Finland) and Claes Uggla (Sweden) The directive[1] is applied for most of the important forest tree species in Europe, 47 in total (see annex 1 of the Directive, link below). Other tree species are not covered by...
