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.

热带低地雨林将大规模转化为以油棕榈为主导的景观，导致了生物多样性和生态功能的巨大损失。一种有希望的生态系统修复方法可能是在油棕种植园的海洋中建立树岛。为了测试这一论点，我们通过在大型油棕种植园中建立52个树岛来建立生物多样性富集实验。该实验成立于2013年，包括不同大小的岛屿和种植树木的不同多样性水平。第一年的特征是多个分类单元的多样性和许多生态系统功能的多样性增加，两种实验治疗（即岛屿的大小和树木多样性）的显着影响。与共同的概念相反，增强生物多样性和生态系统功能并不能以农业生产率为代价，即在景观量表上产生产量。我们假设观察到的多样性和多功能性的增加将随着时间的流逝而进一步增强，但是以产量的权衡会出现。接下来三年的目标包括（a）维护实验和核心监测计划，（b）分析两种实验治疗方法在工作中的长期影响（岛屿的大小和树木多样性），c）研究生态系统轨迹的研究，包括多个组件的恢复，以及d）的扩展整合营养过程。拟议的工作将与合作伙伴项目密切合作，以解决生态食品网，景观级别的分析，气候法规，经济学和政策，并使用基于代理的建模。努力将为联合国生态系统恢复十年做出基于证据的贡献。
