Moreover, restoration has been heralded as an “acid test” of ecological understanding, by affording the ability to study community assembly, ecosystem function, and human influence over ecosystems across large spatial and long temporal scales. These data sets report the outcome of community assembly, in terms of plant community composition and structure and one important ecosystem function (aboveground biomass production), in 29 prairie restorations in southwestern Michigan. We also report putative forces shaping the outcome of assembly including the species pools (seed mixes applied during restoration), site conditions, landscape context, and land-use history. Detailed knowledge of each restoration effort, including seed mixes used, is unusual and makes these data sets uniquely suited to addressing questions in community assembly by comparing the sown seeds and resulting assembled plant community. For example, we have used the data to test the role of species pools in determining the diversity of assembling communities. We have also used the data to characterize the relative importance of various drivers of community assembly outcomes during restoration, as a step toward resolving the highly contingent and unpredictable outcomes that plague the field of ecological restoration. We suggest that these data sets may prove useful for addressing additional questions in community ecology through the lens of ecological restoration. <i>Key words</i>: <i>aboveground biomass; community assembly; ecosystem function; prairie restoration; seed mix; species pool.</i>

【数据集说明】
生态修复通过助力受干扰或受损生态系统的恢复，在生物多样性保护中发挥着关键作用。此外，生态修复被视为检验生态学认知的“试金石”，使得研究者能够在大空间尺度与长时间跨度下，研究群落组装（community assembly）、生态系统功能（ecosystem function）以及人类对生态系统的影响。

本数据集记录了密歇根州西南部29个草原修复（prairie restoration）样地的群落组装结果，具体涵盖植物群落的组成、结构，以及一项核心生态系统功能：地上生物量生产（aboveground biomass production）。本数据集同时记录了可能影响组装结果的潜在驱动因子，包括物种库（species pool）（修复过程中施用的种子组合（seed mix））、立地条件、景观背景以及土地利用历史。

针对每一项修复工程的详尽记录（包括所使用的种子组合）并不多见，这使得本数据集具备独特优势：可通过比对播种种子与最终形成的植物群落，解答群落组装相关的科学问题。例如，本团队曾利用该数据集验证物种库对组装群落多样性的调控作用；也曾借助该数据集刻画修复过程中群落组装结果的各类驱动因子的相对重要性，以此为解决长期困扰生态修复领域的高度偶然性与不可预测性结果问题提供支撑。

本团队认为，本数据集可用于从生态修复的视角解答群落生态学领域的更多科学问题。
