Assessing the conservation value of restoration plantings is critical to support the global forest landscape restoration movement. We assessed the implications of tree species selection in the restoration of Brazil's Atlantic Forest regarding carbon stocking and species conservation. This assessment was based on a comprehensive dataset of seedling acquisition records from 961 restoration projects, more than14 million seedlings, 192 forest remnants, and functional data from 1,223 tree species. We found that animal‐dispersed trees with larger seeds tend to have higher seed prices, yet are underrepresented in the seedlings acquired for restoration plantations. Compared to forest remnants, fruit supply potentially offered by the species acquired for restoration plantings is lower for birds, but higher for bats. Reduced abundance of medium‐ and/or large‐seeded, animal‐dispersed trees lead to declines of 2.8–10.6% in simulated potential carbon stocking. Given the uncertainty in these estimates, policy interventions may be needed to encourage greater representation of large‐seeded, animal‐dispersed tree species in Atlantic Forest restorations. These findings provide critical guidance for recovering tree functional diversity, plant‐frugivore mutualistic interactions, and carbon stocking in multi‐species tropical forest restoration plantings.

最大限度地保护已恢复的热带森林中的生物多样性和碳储量

评估恢复种植的保护价值对于支持全球森林景观恢复运动至关重要。我们评估了树种选择对巴西大西洋森林恢复中碳储存和物种保护的影响。该评估基于一个全面的数据集，该数据集来自961个恢复项目的苗木收购记录，超过1400万棵树苗，192个森林残留物以及1,223种树种的功能数据。我们发现，种子较大的分散在动物身上的树木的种子价格往往较高，但在恢复人工林获得的幼苗中代表性不足。与森林残余物相比，用于恢复种植的物种可能提供的水果供应量，鸟类较低，而蝙蝠较高。中型和/或大型种子，动物分散的树木减少后，模拟的潜在碳储存量减少了2.8-10.6％。考虑到这些估计数的不确定性，可能需要采取政策干预措施，以鼓励在大西洋森林恢复中更多地种植大种子，动物分散的树种。这些发现为在多物种热带森林恢复种植园中恢复树木功能多样性，植物与果蝇之间的相互作用以及碳储存提供了重要的指导。
