Conservation
Skogforsk is developing nature conservation measures that maximize benefit at minimal cost. The research will enable high and valuable production in forests, combined with effective measures that preserve biodiversity, soil and water.
Current research
Effects of high stumps
In order to develop general conservation, Skogforsk is monitoring 400 high stumps in the area around Grangärde in Dalarna.
