Recent global commitments to forest and landscape restoration in the tropics call for new management approaches that benefit both biodiversity and livelihoods of forest‐dependent people. The sustainable use of wild forest products is a promising pathway, but requires clarity about harvested species' demography and harvesters' rights. Here, we explored how the exploitation of fruits of the threatened palm Euterpe edulis, a key fruit source for wildlife in Brazil's globally important Atlantic Forest biodiversity hotspot, could trigger local community involvement in restoration. This palm has both non‐destructive (fruit) and destructive (palm heart) culinary uses, each with unique biological and resource‐use conditions. We quantified all demographic stages of this species in multiple agroforests, secondary forests, and protected areas to parameterize demographic projections of palm populations, harvest profitability, and fruit provisioning to wildlife under different management scenarios. Field observations showed a clear depression of adult palm populations in protected areas, likely due to palm heart poaching, and of intermediate size classes in agroforests, probably from weeding by farmers. Field data and demographic models reveal that in this region, agroforests and secondary forests can successfully conserve this species while providing lasting profits for farmers under most scenarios. These findings demonstrate a clear case where local stakeholders both contribute to and benefit from restoration through harvest of wild products and also highlight a potential source of income from regenerating tropical forests.

利用濒临灭绝的棕榈树的果实触发巴西大西洋森林的恢复

热带地区最近对森林和景观恢复的全球承诺要求采用新的管理方法,该方法既有利于依赖森林的人们的生物多样性,也有利于他们的生计。野生林产品的可持续利用是一个有前途的途径,但需要明确有关采伐物种的人口统计资料和采伐者的权利。在这里,我们探索了如何开发濒危棕榈紫蝶的果实在巴西具有全球重要意义的大西洋森林生物多样性热点地区,野生动植物的主要果实来源可能会触发当地社区的参与。这种棕榈具有非破坏性(水果)和破坏性(棕榈心)的烹饪用途,每种都有独特的生物学和资源利用条件。我们对多种农林,次生林和保护区中该物种的所有人口统计阶段进行了量化,以参数化棕榈种群,收获获利能力和在不同管理方案下为野生生物提供水果的人口预测。实地观察表明,保护区的成年棕榈种群明显减少,可能是由于棕榈心被偷猎所致;而农用林的中等大小等级则可能是由于农民除草而造成的。现场数据和人口统计模型表明,在该地区,在大多数情况下,农林和次生林可以成功地保护该物种,同时为农民提供持久的利润。这些发现证明了一个明显的案例,即当地利益相关者既可以通过收获野生产品来促进恢复,又可以从中受益,同时也突出了热带森林更新带来的潜在收入来源。
