The ongoing shifts in natural vegetation zones predict the expansion of European beech (Fagus sylvatica L.) into Eastern Baltic region, suggesting it will become a potential alternative to birch (Betula pendula Roth. and Betula pubescens Ehrh.) forest regeneration. For successful application regeneration material, an evaluation susceptibility disturbances (e.g., wind) is necessary for reliable ...
Fire, as a natural ecological disturbance factor in forest, this study located in the Marivan region, Northern Zagros forest, and western Iranian state of Kurdistan. In each burned and unburned area 30 circle sample plot (1000 m2) were collected by randomized–systematic method in the 100×200 m net (in total 60 plots). In every sample plot the kind of species, number of tree, the heig...

چکیده ندارد.
In this chapter we discuss tree species that exhibit rapid growth in northern Europe, i.e. the Nordic and Baltic countries. These species include both common indigenous species and introduced species. We continue with an evaluation of current breeding work and the genetic potential of species that may be suitable for biomass production in this region. Because short rotation times are commonly d...
