• Aim: Determine the long term ecological consequences of stump harvest

Project description: Tree stump biomass is a large potential source for renewable energy. To start stump harvesting, a law demand is that analyses of environmental consequences must be performed. A summary of present knowledge, introduced by STEM, shows that long term, and large scale studies are needed for such an analysis. A possibility for such studies already exists as a consequence of stump harvesting around the Mackmyra area during 1977-89. The harvested area is mapped and the intention of this study is to improve knowledge by comparing environmental parameters in stump harvested areas with areas that are not stump harvested. The BIOCORE involvements consist of a comparision of ground living and wood living beetle communities on harvested and non harvested stands. The new knowledge that this generates can be used for an analysis of the environmental implications of stump harvest and for designing compensatore measures.
