Protecting important sites is a key strategy for halting the loss of biodiversity. However, our understanding of the relationship between management inputs and biodiversity outcomes in protected areas (PAs) remains weak. Here, we examine biodiversity outcomes using species population trends in PAs derived from the Living Planet Database in relation to management data derived from the Management Effectiveness Tracking Tool (METT) database for 217 population time‐series from 73 PAs. We found a positive relationship between our METT‐based scores for Capacity and Resources and changes in vertebrate abundance, consistent with the hypothesis that PAs require adequate resourcing to halt biodiversity loss. Additionally, PA age was negatively correlated with trends for the mammal subsets and PA size negatively correlated with population trends in the global subset. Our study highlights the paucity of appropriate data for rigorous testing of the role of management in maintaining species populations across multiple sites, and describes ways to improve our understanding of PA performance.

陆地保护区管理能力和生态成果的全球分析

保护重要地点是制止生物多样性丧失的一项关键战略。但是，我们对保护区管理投入和生物多样性成果之间关系的理解仍然很薄弱。在这里，我们使用来自生命星球数据库的PA中物种种群趋势与来自73个PA的217个人口时序的管理有效性跟踪工具（METT）数据库得出的管理数据相关的生物多样性成果进行了研究。我们发现，基于METT的能力和资源得分与脊椎动物数量变化之间存在正相关关系，这与保护区需要足够资源以制止生物多样性丧失的假设相一致。此外，PA年龄与哺乳动物亚群的趋势呈负相关，PA大小与全球亚群的种群趋势呈负相关。我们的研究强调了缺乏足够的数据来严格测试管理在维护多个地点物种种群中的作用，并描述了增进对PA表现的理解的方法。
