Protected areas are not only crucial for biodiversity and natural processes but also for recreation. Although a benign neglect strategy of dealing with natural disturbances in protected areas is beneficial for nature, public debate on avoiding increased pest population growth has intensified. We evaluated the effect of mechanical pest control measures in decreasing populations of insect pests, maintaining nontarget biodiversity, retaining high recreational value, and keeping economic costs low. Debarking and bark scratching or gouging effectively prevented infestation of felled trees by European spruce bark beetles (Ips typographus) and controlled the beetles in recently infested trees. Bark scratching or gouging retained biodiversity at natural levels, whereas debarking decreased biodiversity by 54% with higher economic costs. The public rated bark‐gouged trees more positively than debarked trees. We thus urge authorities to promote bark scratching or gouging in the control of bark beetles in protected areas instead of salvage logging and debarking.

协调针叶林中的虫害控制，自然保护和休闲

保护区不仅对于生物多样性和自然过程至关重要，而且对于娱乐活动也至关重要。尽管处理保护区中自然干扰的良性忽视策略对自然有益，但有关避免有害生物种群增长的公开辩论仍在加剧。我们评估了机械虫害控制措施在减少虫害数量，维持非目标生物多样性，保持较高的娱乐价值以及保持较低的经济成本方面的效果。剥皮和树皮刮擦或刨削有效地防止了欧洲云杉的树皮甲虫对砍伐树木的侵扰（Ips typographus）并控制了最近出没过的树木中的甲虫。树皮的刮擦或刨削将生物多样性保留在自然水平上，而剥皮则使生物多样性减少了54％，同时增加了经济成本。公众对树皮凿树的评价高于对树皮树的评价。因此，我们敦促当局在保护区控制树皮甲虫的过程中促进树皮的刮擦或刨削，而不是打捞和剥皮。
