Bastin et al. (Reports, 12 May 2017, p. 635) infer forest as more globally extensive than previously estimated using tree cover data. However, their forest definition does not reflect ecosystem function or biotic composition. These structural and climatic definitions inflate forest estimates across the tropics and undermine conservation goals, leading to inappropriate management policies and practices in tropical grassy ecosystems.

评论“旱地生物群落中的森林范围”

巴斯汀等人。（报告，2017 年 5 月 12 日，第 635 页）推断森林比之前使用树木覆盖数据估计的全球范围更广。然而，它们的森林定义并不反映生态系统功能或生物组成。这些结构和气候定义夸大了整个热带地区的森林估计并破坏了保护目标，导致热带草地生态系统的管理政策和做法不当。
