Bird Frugivore Abundance data from: Applied nucleation facilitates tropical forest recovery

Applied nucleation, mostly based upon planting tree islands, has been proposed as a cost‐effective strategy to meet ambitious global forest and landscape restoration targets. We review results from a 15‐year study, replicated at 15 sites in southern Costa Rica, that compares applied nucleation to natural regeneration and mixed‐species tree plantations as strategies to restore tropical forest. We have collected data on planted tree survival and growth, woody vegetation recruitment and structure, seed rain, litterfall, epiphytes, birds, bats and leaf litter arthropods. Our results indicate that applied nucleation and plantation restoration strategies are similarly effective in enhancing the recovery of most floral and faunal groups, vegetation structure and ecosystem functions, as compared to natural regeneration. Seed dispersal and woody recruitment are higher in applied nucleation and plantation than natural regeneration treatments; canopy cover has increased substantially in b...以营造树岛为核心实施路径的人工成核恢复法（Applied nucleation），已被提出为一种可助力达成宏伟全球森林与景观修复目标的经济高效策略。 本研究综述了一项为期15年的多站点试验成果，该试验在哥斯达黎加南部的15个样点重复开展，对比了人工成核恢复法、自然恢复与混交人工林三种热带森林修复策略的修复效果。研究团队采集了如下多维度观测数据：人工栽植树木的存活率与生长动态、木本植被的自然更新与群落结构、种子雨通量、凋落物产量、附生植物群落、鸟类与蝙蝠种群，以及地表凋落物中的节肢动物群落。 研究结果显示，相较于自然恢复，人工成核恢复法与人工林修复策略在促进多数动植物类群、植被结构与生态系统功能恢复方面效果相当。 种子传播效率与木本植被更新率在人工成核恢复法与人工林处理样地中均显著高于自然恢复样地；冠层覆盖度在b...中已大幅提升。
