USDA Plant Database

Features: The USDA Plant Database serves as a centralized, authoritative source for standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the United States and its territories. It features high-resolution plant imagery, interactive distribution maps, scientific classification, and detailed fact sheets. Users can search by common or scientific name, access federally listed threatened or endangered status, and review plant growth habits, toxicity, and ecological significance.

History: Developed and maintained by the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), the database was established to provide a unified reference point for botanical research, land management, and conservation efforts. It evolved from the need to organize vast amounts of national plant data into a digital, publicly accessible format to support environmental stewardship and regulatory compliance across North America.

Use cases: It is an essential tool for botanists and ecologists conducting field research, students studying plant taxonomy, and gardeners looking for native plant species suitable for specific soil and climate conditions. Land managers and conservationists use it to identify invasive species and track native plant distributions, while educators utilize its rich library of photos and scientific data to develop curriculum on regional biodiversity and habitat preservation.
