The large-scale conversion of tropical lowland rainforest into landscapes dominated by monocultures of oil palm has led to significant losses in biodiversity and ecological functions. One promising approach to ecosystem restoration could be to establish tree islands in the sea of oil palm plantations. To test this contention, we set up the biodiversity enrichment experiment EFForTS-BEE by establishing 52 tree islands in a large oil palm plantation. Established in 2013, the experiment comprises islands of different sizes and different diversity levels of planted trees and was. The first years were characterized by increases in the diversity of multiple taxa and many ecosystem functions with significant effects of both experimental treatments, i.e. island size and tree diversity. In contrast to the common notion, enhancing biodiversity and ecosystem functioning have not come at the expense of agricultural productivity, i.e., yield, at the landscape scale. We hypothesize that the observed increases in multi-diversity and multi-functionality will further strengthen over time but trade-offs with yield will emerge. The objectives for the next three years include (a) the maintenance of the experiment and a core monitoring program, (b) an analysis of the long-term effects of the two experimental treatments in EFForTS-BEE (island size and tree diversity), c) the study of ecosystem trajectories, including the restoration of multiple components, and d) an extended integration of trophic processes. The proposed work will be done in close collaboration with partner projects addressing ecological food webs, landscape-level analyses, climate regulation, economics and policies, and using agent-based modelling. EFForTS-BEE will enable and foster an evidence-based contribution to the UN Decade of Ecosystem Restoration.

热带低地雨林大规模转变为以油棕单一种植为主的景观，导致生物多样性和生态功能严重丧失。一种有前途的生态系统恢复方法可能是在油棕种植园的海洋中建立树岛。为了验证这一论点，我们在一个大型油棕种植园中建立了 52 个树岛，建立了生物多样性富集实验 EFForTS-BEE。该实验成立于 2013 年，由不同大小的岛屿和不同多样性水平的种植树木组成。第一年的特点是多个类群和许多生态系统功能的多样性增加，这两种实验处理（即岛屿大小和树木多样性）产生了显着影响。与普遍观念相反，增强生物多样性和生态系统功能并不以牺牲景观规模的农业生产力（即产量）为代价。我们假设观察到的多多样性和多功能性的增加将随着时间的推移进一步加强，但会出现与产量的权衡。未来三年的目标包括 (a) 维持实验和核心监测计划，(b) 分析 EFForTS-BEE 中两种实验处理的长期影响（岛屿大小和树木多样性）， c) 生态系统轨迹研究，包括多个组成部分的恢复，以及 d) 营养过程的扩展整合。拟议的工作将与涉及生态食物网、景观水平分析、气候调节、经济和政策以及使用基于主体的建模的合作伙伴项目密切合作完成。 EFForTS-BEE 将为联合国生态系统恢复十年做出基于证据的贡献。
