Forest restoration projects involving active planting should prioritize species that are useful to local communities, while also considering species' threat status and resistance to local stress factors, but scientific knowledge on these criteria is scarce, especially in understudied tropical ecosystems. We hypothesized that local ecological knowledge can help to fill this gap. Through interviews with 47 local experts and 197 randomly selected households in 8 rural communities of the tropical dry forests of northwestern Peru and southern Ecuador, we identified the species perceived as most useful, most threatened, and most resistant to local stress factors. To better understand the studied local ecological knowledge, we also explored the following research questions and their implications for species selection decisions: (1) How does species' potential usefulness compare to their active use? (2) How does species' perceived threat status relate to their usefulness? (3) Does local knowledge on species' resistance to local stress factors corroborate scientific knowledge? We found large differences between the potential and active use of species and illustrate how data on both can yield useful insights. Furthermore, we found that species' perceived threat status was mainly linked to their usefulness for construction wood, and that the vast majority of local perceptions on species' threat status and stress resistance coincided with scientific knowledge. Our findings illustrate the large potential of local ecological knowledge for improving species selection strategies and thereby increasing the success of forest restoration efforts worldwide.

地方生态知识在热带干旱林恢复中指导树种选择的价值

涉及积极种植的森林恢复项目应优先考虑对当地社区有用的物种,同时还要考虑物种的威胁状况和对当地压力因素的抵抗力,但关于这些标准的科学知识很少,特别是在研究不足的热带生态系统中。我们假设当地生态知识可以帮助填补这一空白。通过与秘鲁西北部和厄瓜多尔南部热带干旱森林 8 个农村社区的 47 位当地专家和 197 个随机选择的家庭的访谈,我们确定了被认为最有用、最受威胁和最能抵抗当地压力因素的物种。为了更好地了解所研究的当地生态知识,我们还探讨了以下研究问题及其对物种选择决策的影响:(1) 与它们的积极使用相比,物种的潜在有用性如何?(2) 物种感知的威胁状态与它们的有用性有何关系?(3) 关于物种对当地胁迫因素的抵抗力的当地知识是否证实了科学知识?我们发现物种的潜在使用和积极使用之间存在巨大差异,并说明了两者的数据如何产生有用的见解。此外,我们发现物种的感知威胁状态主要与其对建筑木材的有用性有关,并且绝大多数当地对物种威胁状态和抗逆性的感知与科学知识相吻合。我们的发现说明了当地生态知识在改进物种选择策略方面的巨大潜力,从而提高了全球森林恢复工作的成功率。与其积极使用相比,潜在的有用性?(2) 物种感知的威胁状态与它们的有用性有何关系?(3) 关于物种对当地胁迫因素的抵抗力的当地知识是否证实了科学知识?我们发现物种的潜在使用和积极使用之间存在巨大差异,并说明了两者的数据如何产生有用的见解。此外,我们发现物种感知的威胁状态主要与它们对建筑木材的有用性有关,并且绝大多数当地对物种威胁状态和抗逆性的感知与科学知识相吻合。我们的发现说明了当地生态知识在改进物种选择策略方面的巨大潜力,从而提高了全球森林恢复工作的成功率。与其积极使用相比,潜在的有用性?(2) 物种感知的威胁状态与它们的有用性有何关系?(3) 关于物种对当地胁迫因素的抵抗力的当地知识是否证实了科学知识?我们发现物种的潜在使用和积极使用之间存在巨大差异,并说明了两者的数据如何产生有用的见解。此外,我们发现物种感知的威胁状态主要与它们对建筑木材的有用性有关,并且绝大多数当地对物种威胁状态和抗逆性的感知与科学知识相吻合。我们的发现说明了当地生态知识在改进物种选择策略方面的巨大潜力,从而提高了全球森林恢复工作的成功率。
