我们估计了维持瑞典森林生物多样性所需的自然保护区。利用栖息脊椎动物保护伞物种长期生存的生境丧失阈值和森林干扰机制的差异，对四个生物地理区域的长期保护进行了估算。假定正常管理可以模拟的森林环境不需要储备。对保护区长期需求的估计从9%（瑞典北部）到16%（瑞典最南部）不等，并分为：(1)现有保护森林（1.6-0.6%）；(2)特殊森林管理对生物多样性的估计效益（0.7-0%）；(3)现有具有高保护价值的未保护森林（3.5-1.9%）。满足长期保护目标的剩余面积为文化景观栖息地（0-2.2%）和栖息地恢复和再创造用地（3-11%）。我们的分析表明，迫切需要保护所有的自然森林和文化景观栖息地，但仅靠保护森林不足以维持森林生物多样性。
We estimated the need for nature reserves to maintain forest biodiversity in Sweden. Using habitat-loss thresholds for long-term survival of resident vertebrate "umbrella" species, and differences in forest disturbance regimes, we estimated the long-term protection in four biogeographic regions. No reserve need was assumed for forest environments that can be emulated by normal management. The estimates of the long-term need of reserves ranged from 9% (northern Sweden) to 16% southernmost Sweden) and was divided into: (1) existing protected forests (1.6-0.6%): (2) estimated benefits for biodiversity of special forest management (0.7-0%): (3) existing unprotected forests with high conservation value (3.5-1.9%). The remaining areas required to satisfy the long-term reserve goal were cultural landscape habitats (0-2.2%), as well as land for habitat restoration and re-creation (3-11%). Our analysis suggests that it is urgent to maintain all remnants of natural forests and cultural landscape habitats, but that forest protection alone is insufficient to maintain forest biodiversity.
