Abstract Integrative management strategies that simultaneously aim for wood production and biodiversity conservation are considered crucial to protect biodiversity of forest species outside protected areas. In this study, we evaluated whether deadwood enrichment as an integrative strategy at a scale of 17,000 ha resulted in enhanced biodiversity of saproxylic and non-saproxylic taxa eight years after the implementation of the strategy. The strategy included active deadwood enrichment with harvest remnants, retention of deadwood, and nature forest reserves areas. The analysis was based on data on the occurrence of plants, fungi, beetles, true bugs and birds from directly before and after the implementation of the strategy. The implementation of the strategy resulted in an increase in the deadwood amount by an average of 90 ± 40 m3 ha−1 (mean ± SE) over this period. While deadwood amounts doubled in production forests (+90%), they increased even more in nature forest reserves (+160%). Multidiversity (species density of all taxa) increased with an increase in deadwood amount; this was a result of an increase in the multidiversity of saproxylic species as the non-saproxylic multidiversity did not respond. Among single taxon groups, fungal and beetle species density responded positively to the increase in deadwood amount, especially when only saproxylic species were analysed. Importantly, this effect was not only found in the nature forest reserves, but also in the production forests. We thus conclude that active deadwood enrichment in production forests and nature forest reserves is a promising tool to rapidly promote the protection of forest biodiversity.

结合综合和隔离保护元素的枯木富集增强了管理林中多种类群的生物多样性

摘要 同时以木材生产和生物多样性保护为目标的综合管理策略被认为对保护保护区外森林物种的生物多样性至关重要。在这项研究中，我们评估了作为 17,000 公顷规模的枯木富集的综合策略，在该策略实施 8 年后是否会增强腐木和非腐木类群的生物多样性。该策略包括利用收获的残余物进行积极的枯木浓缩、保留枯木和自然森林保护区。该分析基于该战略实施前后的植物、真菌、甲虫、真正的昆虫和鸟类的发生数据。在此期间，该策略的实施导致枯木量平均增加了 90 ± 40 m3 ha-1（平均值 ± SE）。虽然生产林中的枯木数量翻了一番 (+90%)，但它们在自然森林保护区 (+160%) 中增加得更多。多样性（所有分类群的物种密度）随着枯木数量的增加而增加；这是由于腐氧基物种的多样性增加，因为非腐氧基多样性没有反应。在单一分类群中，真菌和甲虫物种密度对枯木数量的增加有积极的反应，特别是当只分析腐木物种时。重要的是，这种影响不仅存在于自然森林保护区，也存在于生产林中。
