**概述**
本要素服务提供来自不同机构与各州的草原重建倡议（Prairie Reconstruction Initiative）综合数据集。该服务整合空间数据与表格数据，涵盖播种区域、种植单元、育苗块种植区、调查数据以及物种信息等维度，为生态修复工作提供有力支撑。

**要素图层**
- 播种区域（Seeded Area）：包含表征草原种子播种区域的面要素。其属性字段涵盖种植年份、播种方式、整地详情、成本、入侵物种存在情况以及目标草原群落信息，可用于评估修复实践与场地现状。
- 种植单元（Planting Unit）：代表与生态、水文、美学、土壤保持以及栖息地营造目标关联的种植单元区域。该图层提供联系方式与访问权限信息，便于修复单元的管理与协调工作。
- 育苗块种植区（Plug Area）：包含育苗块与裸根种植活动详情的面状数据，涵盖作业方信息、种植类型、场地条件、种植方式、成本、浇水事件以及土壤生理特性等内容。
- 场地（Site）：为修复项目提供空间背景信息，包含场地管理所需的运营机构与办公信息，以及元数据记录。
- 嵌套点与蜿蜒线调查数据（Nested Point and Meandering Line Survey Data）：采用PRI监测规范获取的调查观测空间要素，包含点状与线状特征，涵盖调查人员信息、调查时间、物种存在情况与丰度数据，可用于监测草原重建进度并开展生物多样性评估。

**许可条款**
