USDA PLANTS Database

The USDA PLANTS Database is a federally maintained botanical information system that catalogs vascular plants, bryophytes, and lichens for the United States and its territories. It serves as a central resource linking taxonomic treatment, distributional data, conservation status, and nomenclatural authority for land managers, researchers, educators, and policymakers. The database integrates federally recognized lists, regional floras, and institutional specimen records to support biodiversity assessment, restoration, and regulatory compliance.

Overview and Purpose

The database aims to provide authoritative plant names, standardized symbols, and geographic distribution data to support agencies such as the United States Department of Agriculture, National Park Service, United States Fish and Wildlife Service, Bureau of Land Management, and academic institutions like the Smithsonian Institution and New York Botanical Garden. It underpins programs including the Endangered Species Act implementation, National Environmental Policy Act analyses, and vegetation mapping used by the Federal Highway Administration and United States Forest Service. By aggregating nomenclatural authority from sources such as the International Code of Nomenclature for algae, fungi, and plants and regional floras like the Flora of North America, it supports consistency across United States Geological Survey surveys, conservation plans by The Nature Conservancy, and botanical research conducted at universities such as Harvard University and University of California, Berkeley.

Data Content and Taxonomy

Content includes accepted scientific names, synonyms, common names, growth forms, native status, and legal conservation status. Taxonomic treatments draw on reference works such as the Flora of North America, the Kew Gardens databases, and checklists curated by institutions including the Missouri Botanical Garden and the Royal Botanic Gardens, Kew. The database records distribution by US state and territory, linking to regional classifications used by agencies like the National Oceanic and Atmospheric Administration for coastal plants and the Natural Resources Conservation Service for agronomic species. Taxonomic hierarchy follows standards referenced by the International Plant Names Index and botanical authorities such as Carl Linnaeus historically and modern curators at the Botanical Research Institute of Texas.

Database Structure and Access

The PLANTS framework provides web-based query tools, downloadable data sets, and symbol codes for interoperability with systems used by Esri, Google, and academic GIS labs at institutions like Penn State University and Oregon State University. Access levels support desktop browsing, batch downloads, and API-like services consumed by platforms developed at the United States Geological Survey and by research groups at Cornell University and University of Florida. Metadata conventions align with standards referenced by the Biodiversity Heritage Library and data repositories curated by the Integrated Digitized Biocollections initiative. Users access range maps, image galleries, and specimen citations drawn from herbaria such as the New York Botanical Garden Herbarium, the United States National Herbarium, and university collections at University of Michigan.

Applications and Uses

Practitioners across conservation, agriculture, and education use the database for species inventories, restoration planning, weed risk assessments, and regulatory compliance. Conservation NGOs like The Nature Conservancy and federal programs such as the National Wildlife Refuge System rely on PLANTS-derived lists for habitat management. Agricultural researchers at the United States Agricultural Research Service and land-grant universities apply its native status and weed information to cropping system design and invasive species control. Educators at museums like the Field Museum and botanical gardens use image and trait data to develop curricula and outreach exhibits. Geographic data feed into landscape-scale models used by the Intergovernmental Panel on Climate Change contributors and regional planning by entities such as the Metropolitan Transportation Authority.

History and Development

Initiated in the 1990s, the system evolved from earlier printed checklists and card catalogs maintained by USDA staff and collaborating herbaria. Development involved partnerships with major botanical institutions including the Missouri Botanical Garden, the New York Botanical Garden, and academic consortia at University of Wisconsin–Madison and University of California, Davis. Over time it incorporated electronic specimen records from networks like the Consortium of Northeastern Herbaria and standards promulgated by organizations such as the Catalogue of Life and the Global Biodiversity Information Facility. Updates have reflected taxonomic revisions from influential botanists and monographers affiliated with institutions such as Kew and regional floras edited by scholars at Duke University and Ohio State University.

Data Standards, Quality, and Licensing

Data quality relies on curation by USDA botanists and partner herbaria, cross-referencing nomenclatural authorities including the International Plant Names Index and the TROPICOS database. Standards for geographic and taxonomic metadata align with practices used by the Global Biodiversity Information Facility and the Biodiversity Information Standards (TDWG). Licensing typically allows public use of data with attribution to the United States Department of Agriculture and follows federal data policies that intersect with intellectual property frameworks administered by agencies such as the Library of Congress and legal standards from the United States Code. Continuous vetting and community feedback from institutions like the Botanical Society of America and regional herbaria ensure reliability for regulatory, research, and educational applications.
