As global tree-growing efforts have escalated in the past decade, copious failures and unintended consequences have prompted many reforestation best practices guidelines. The extent to which organizations have integrated these ecological and socioeconomic recommendations, however, remains uncertain. We reviewed websites of 99 intermediary organizations that promote and fund tree-growing projects to determine how well they report following best practices. Nearly half the organizations stated tree or area planting targets, but only 25% had measurable, time-bound objectives. Most organizations discussed the benefits local communities would receive from trees, but only 38% reported measures of these outcomes. Nonprofit organizations with greater prior experience converged more closely on best practices, and their level of scientific expertise was positively associated with clearer project selection standards. Although many tree-growing organizations acknowledge the importance of clear goals, local community involvement, and monitoring, our results raise questions regarding whether long-term benefits are being achieved and emphasize the need for stronger public accountability standards.

将最佳实践应用于全球树木种植工作的进展和不足

随着过去十年全球植树活动的不断升级，大量的失败和意想不到的后果催生了许多重新造林最佳实践指南。然而，组织在多大程度上整合了这些生态和社会经济建议仍然不确定。我们审查了 99 个促进和资助植树项目的中介组织的网站，以确定他们报告遵循最佳实践的情况。近一半的组织制定了树木或面积种植目标，但只有 25% 的组织制定了可衡量的、有时限的目标。大多数组织讨论了当地社区将从树木中获得的好处，但只有 38% 的组织报告了这些成果的衡量标准。拥有更多经验的非营利组织更接近最佳实践，其科学专业水平与更清晰的项目选择标准呈正相关。尽管许多树木种植组织承认明确目标、当地社区参与和监测的重要性，但我们的结果提出了关于是否实现长期利益的问题，并强调需要更强的公共问责标准。
