机构定位与历史沿革
PLANTS 植物数据库的前身是 NRCS 前身——美国土壤保持局（Soil Conservation Service）在 1971 年发布的 National List of Scientific Plant Names 全国植物科学名称名录，1982 年修订再版，是 PLANTS 植物符号编码体系的源头。1990 年代后期数据库正式上网公开并迁入官方站点持续运营至今，被联邦、州、地方各级机构和私人组织视为国家植物命名与分布的标准依据。日常运营由总部位于北卡罗来纳州格林斯博罗的 NRCS 东国家技术支援中心负责。
数据范围与覆盖规模
PLANTS 收录的物种档案涵盖美国本土 50 个州、波多黎各、美属维京群岛、关岛以及其他海外领地的全部维管植物，并延伸到苔藓、苔类、角苔和地衣。早期公开快照曾记录约 9 万条物种与种下记录，图像库自 2010 年代突破 5 万张图片以来持续扩充。每个物种配有植物符号（PLANTS Symbol）、学名与俗名、州一级分布图、物种摘要、形态特征、影像与参考文献等标准化字段。
检索工具与方法体系
数据库提供按名称、植物符号、植物特性、寿命、生长型、群组、湿地指示状态、稀有保护等级、州分布、外来入侵名单等多个入口的专项检索，Characteristic Search 特性检索可对接 NRCS 80 余项保护植物特性字段，是评估物种在保育、植被恢复与农林业应用中的核心工具。搜索结果支持 JSON 与 CSV 导出，方便研究人员、生态顾问与高校学生下载再做二次分析。
技术合作与团队构成
PLANTS 由 NRCS 国家植物数据团队（NPDT）牵头，与 NRCS 信息技术中心（ITC）、美国国家信息技术中心（NITC）以及 BLM、USFS、USFWS、ARS、APHIS 等多家联邦机构长期合作，并接受各州自然遗产网络、州立大学与植物园协会的物种数据回传。团队的专长涵盖植物分类学、林学、植物生理学、植被科学、民族植物学、生态学与分类数据库开发。
应用场景与社会价值
PLANTS 数据库被广泛用于联邦与州土地保育、植被恢复项目规划、农林业生产决策、外来入侵物种预警、濒危物种评估、园艺植物身份核对与公民科学教育。NRCS 借助 PLANTS 跨机构、跨学科的标准命名体系降低重复采集与识别的成本，对学者、教育工作者、园艺师、保护从业者和农户都是免费公开的国家级参考工具。
Institutional Background and History
The USDA PLANTS Database is the standardized national plant information catalog maintained by the National Plant Data Team (NPDT) within the Natural Resources Conservation Service (NRCS), an agency of the United States Department of Agriculture. The database traces its roots to the National List of Scientific Plant Names published by the Soil Conservation Service in 1971 and revised in 1982, which originated the PLANTS Symbol naming convention still in use. It was launched online in the late 1990s and has continued to operate under the NRCS East National Technology Support Center in Greensboro, North Carolina.
Data Scope and Coverage
PLANTS covers vascular plants, mosses, liverworts, hornworts, and lichens across all 50 U.S. states, Puerto Rico, the U.S. Virgin Islands, Guam, and other U.S. territories. Earlier public snapshots of the underlying checklist counted roughly 90,000 species and infraspecific records, while the image gallery has grown past 50,000 photographs. Each plant profile includes the PLANTS Symbol, scientific and common names, distribution by state, species abstracts, characteristics, images, and references.
Search Tools and Methods
The database offers specialized searches by name, plant symbol, characteristics, duration, growth habit, group, wetland indicator status, rarity, state distribution, and invasive or noxious status. The Characteristic Search engine maps against more than 80 NRCS conservation plant characteristics and supports JSON or CSV export for downstream analysis by ecologists, consultants, and students.
Technical Partnerships and Team
PLANTS is led by the National Plant Data Team (NPDT) within the NRCS, working alongside the NRCS Information Technology Center (ITC), the National Information Technology Center (NITC), and partners including BLM, USFS, USFWS, ARS, and APHIS. The team draws on specialists in plant taxonomy, forestry, plant physiology, range science, ethnobotany, ecology, and taxonomic database development, with contributions from state natural heritage networks and botanical institutions.
Applications and Public Value
PLANTS supports federal and state land conservation, vegetation restoration planning, agriculture and forestry decisions, invasive species alerts, endangered species assessments, horticultural identity verification, and citizen science education. By offering a single national standard for plant naming and distribution, PLANTS reduces duplication across agencies and disciplines and remains a free public reference for researchers, educators, gardeners, conservationists, and farmers.
