许多报告的影响，传统的抢救性伐木，清除倒下和损坏的树木后，灾难性的风对随后的森林恢复集中在短期的结果发生在不到20年，但是，这个时间尺度是不够的，特别是对于北方森林，因为树木生长所需的时间。在这里，我们研究的长期影响救助伐木后，灾难性的风灾事件在1954年对北方森林的恢复力，通过评估针叶树的持续招聘，典型的针叶树种的优势，并为未来的招聘潜力。我们针对两个地区不同比例的针叶树，受到三个干扰和管理的历史：风抛（WT：倒下的树木完好无损），风抛和打捞（WT+SL：打捞记录后的风抛），和老增长（OG：不受风抛）。在这两个地区，过去的抢救对针叶树的持续补充和未来补充的潜力产生了严重的负面影响。仅在混交林中观察到对典型针叶树种优势度的负面影响。结果表明，与针叶林相比，混交林的恢复力较弱，即：森林保持其特征的能力，通过风干扰和抢救性采伐后典型针叶树物种的优势和补充来评估。我们发现，抢救性采伐可能会影响森林结构，甚至60年后，通过破坏先进的增长，包括潜在的母树，苗圃床的典型针叶树种的幼苗。
Many reports on the effects of conventional salvage logging—the removal of fallen and damaged trees after a catastrophic windthrow—on subsequent forest restoration have focused on short-term results occurring over less than 20 years; however, this time scale is inadequate, especially for boreal forests, because of the time required for tree growth. Here, we examine the long-term effects of salvage logging after a catastrophic windthrow event in 1954 on the resilience of a boreal forest by assessing the continuous recruitment of coniferous trees, dominance of typical coniferous tree species, and potential for future recruitment. We targeted two regions with different proportions of coniferous trees that were subject to three disturbance and management histories: windthrow (WT: fallen trees left intact), windthrow and salvage (WT+SL: salvage logged after the windthrow), and old growth (OG: not affected by the windthrow). In both regions, past salvaging has had serious negative impacts on the continuous recruitment of coniferous trees and potential for future recruitment. Negative impacts on the dominance of typical coniferous tree species were only observed in mixed forests. Our results suggest that in comparison to the coniferous forest, the mixed forest was less resilient, i.e.; the capability of a forest to maintain its identity as assessed by the dominance and recruitment of typical conifer species after wind disturbance and salvage logging. We found that salvage logging could affect forest structure, even 60 years later, by destroying advanced growth, including potential mother trees, and nursery beds for seedlings of typical conifer tree species.
