We have compared using simulations the consequences of two of these alternatives − setting aside young forests or extending rotation periods − to that of current practice in managed boreal forest. In all scenarios we applied a constant conservation budget and predicted forest development and harvesting over 200 years. As a proxy for biodiversity conservation, we projected the extinction risk of a dead wood-dependent beetle, Diacanthous undulatus, in a 50 km2 landscape in central Sweden, using a colonization-extinction model. During the first century, setting aside young forest stands rather than old stands increased extinction risk because young stands have lower habitat quality. However, habitat quality of young forests increased as they aged and they were much cheaper to set aside than old stands. Therefore, the strategy allowed a larger set-aside area (within the budget constraint), resulting in lower extinction risk and harvested timber volumes in the second century. Prolonging rotations also decreased the extinction risk but was in the long-term less cost-effective. The most cost-effective strategy in the long-term (200 years) was to set aside a mixture of old and young forest. However, setting aside young stands rather than prolonging rotations or setting aside old stands delays both the benefits (lower extinction risk) and costs (lost harvest volumes), so the optimal strategy depends on the assumed societal values and hence discount rates. date: 2016-12 date_type: published publisher: Elsevier id_number: doi:10.1016/j.biocon.2016.10.017 creators_browse_id: 162 full_text_status: public publication: Biological Conservation volume: 204 pagerange: 197-204 refereed: TRUE issn: 1873-2917 coversheets_dirty: FALSE fp7_project: no fp7_type: info:eu-repo/semantics/article citation: Ranius, T., Korosuo, A. , Roberge, J.-M., Juutinen, A., Mönkkönen, M., & Schroeder, M.
