Investigations on water balance, soil fertility and microbial decomposition processes were conducted on a 20-year old windthrow site. The former spruce monoculture is now replaced by mixed stand of birch (Betula pendula), trembling aspen (Populus tremula), spruce (Picea abies) and oak (Quercus robur). The site is located in a warm area at low altitude on heavy soils, where the unfavourable environmental conditions for spruce trees are prevailing. the aim of this project part was to determine whether birch could be considered as beneficial to forest re-growth in this area. In addition possible ecological effects of different trees concerning litter decomposition, carbon sequestration and the emission of greenhouse gases could be detected.
