Salvage logging, or logging after natural disturbances such as wildfires, insect outbreaks, and windstorms, is carried out to recover some of a forest's natural and/or economic capital. However, trade‐offs between management objectives and a lack of consensus on the ecological consequences of salvage logging impair science‐based decision making on the management of forests after natural disturbances. We conducted a global meta‐analysis of the impacts of salvage logging on regulating ecosystem services and on fuel loads, as a frequent post‐disturbance objective is preventing subsequent wildfires that could be fueled by the accumulation of dead trunks and branches. Salvage logging affected ecosystem services in a moderately negative way, regardless of disturbance type and severity, time elapsed since salvage logging, intensity of salvage logging, and the group of regulating ecosystem services being considered. However, prolonging the time between natural disturbance and salvage logging mitigated negative effects on regulating ecosystem services. Salvage logging had no overall effect on surface fuels; rather, different fuel types responded differently depending on the time elapsed since salvage logging. Delaying salvage logging by ~2–4 years may reduce negative ecological impacts without affecting surface fuel loads.

打捞伐木对调节生态系统服务和燃料负荷的影响

进行伐木或自然灾害(如野火,昆虫暴发和暴风雨后)的伐木,以恢复森林的某些自然和/或经济资本。但是,管理目标之间的权衡取舍以及对打捞伐木的生态后果缺乏共识,这损害了自然干扰后基于科学的森林管理决策。我们对打捞日志对调节生态系统服务和燃料负荷的影响进行了全球荟萃分析,因为频繁的扰乱后目标是防止随后的野火,这些野火可能因死树干和树枝的堆积而加剧。打捞记录以中等程度的消极方式影响生态系统服务,无论干扰类型和严重性,打捞记录后经过的时间,打捞记录的强度,以及正在考虑的一组调节生态系统服务。但是,延长自然干扰和打捞记录之间的时间可以减轻对调节生态系统服务的负面影响。打捞测井对地面燃料没有整体影响。相反,不同类型的燃料根据打捞记录以来所经过的时间做出不同的响应。将打捞记录延迟约2-4年可减少负面的生态影响,而不会影响地面燃料负荷。
