Naturally regenerated forests and managed tree systems provide different levels of carbon, biodiversity, and livelihood benefits. Here, we show that tree cover gains in the moist tropics during 1982-2015 were 56% ± 3% naturally regenerated forests and 27% ± 2.6% managed tree systems, with these differences in forest type, not only natural conditions (climate, soil, and topography), driving observed carbon recovery rates. The remaining 17% ± 3% likely represents small, unmanaged tree patches within non-forest cover types. Achieving global forest restoration goals requires robust monitoring, reporting, and verification of forest types established by restoration initiatives.
自然再生林和人工管理的树木系统提供不同程度的碳、生物多样性和生计效益。我们在此表明，1982年至2015年期间，潮湿热带地区树木覆盖面积的增加中，自然再生林占56%±3%，人工管理的树木系统占27%±2.6%，造成森林类型差异的不仅是自然条件（气候、土壤和地形），这些差异还影响了观测到的碳恢复率。其余17%±3%可能代表非森林覆盖类型内的小型、未管理树木斑块。要实现全球森林恢复目标，需要对恢复倡议所建立的森林类型进行有力的监测、报告和核实。
