文摘

Given a fixed budget, we compared forest conservation strategies over 200 years. Extinction risks of a metapopulation were used as a proxy of biodiversity. Combining young and old set-asides generated the lowest long-term extinction risk. Prolonging rotations also decreased the extinction risk but was less cost-effective. The optimal strategy depends on the assumed societal values and hence discount rates.
