Management Strategies for Wood Fuel Harvesting—Trade-Offs with Biodiversity and Forest Ecosystem Services

Bioenergy is expected to contribute to mitigating climate change. One major source for bioenergy is woody biomass from forests, including logging residues, stumps, and whole trees from young dense stands. However, at increased extraction rates of woody biomass, the forest ecosystem, its biodiversity, and its ability to contribute to fundamental ecosystem services will be affected. We used simulation and optimization techniques to assess the impact of different management strategies on the supply of bioenergy and the trade-offs between wood fuel harvesting, biodiversity, and three other ecosystem services—reindeer husbandry, carbon storage, and recreation. The projections covered 100 years and a forest area of 3 million ha in northern Sweden. We found that the development of novel and cost-effective management systems for biomass outtake from young dense stands may provide options for a significant supply of bioenergy to the emerging bioeconomy, while at the same time securing biodiversity and important ecosystem values in future stand developments. In addition, there is potential to increase the extraction of harvest residues and stumps while simultaneously improving conditions for biodiversity and the amount of carbon stored in forest ecosystems compared to current levels. However, the projected continuing trend of increased forest density (in terms of basal area) has a negative impact on the potential for reindeer husbandry and recreation, which calls for researching new management strategies on landscape levels.
