Alien Plant Invaders of a Natural Areas

Metadata Updated: August 15, 2019

The Alien Plant Invaders of Natural Areas site provides: (1) a comprehensive national listing of alien invasive species of natural areas in the U.S. (currently around 500 species); (2) a referenced invasive database "USA Weeds"" (to be posted by the summer of 1999); (3) illustrated fact sheets; (4) background information on the problem, including terminology; (5) links to species management experts and other people and organizations in the U.S. and worldwide who can provide extra expertise and assistance; and (6) invasive species policy, press releases, and selected publications. The national list of invasive trees, scrubs, woody vines, herbs, and aquatic plants includes species that have been identified as serious ecosystem invaders by The Nature Conservancy, the U.S. National Park Service, Exotic Pest Plant Councils (California, Florida, Tennessee, Pacific Northwest), native plant societies, universities, and other people and organizations. The list continues to grow as new plants are identified and it is updated as needed. The USA weeds database includes the following information: genus, species, plant type (e.g., herb), family, native range, U.S. distribution, and reference citations for each plant listed. Illustrated fact sheets are written in a consistent format, take a national perspective, and provide information on: identification, native range, habitat and distribution in the U.S., ecological threat, biology and mechanism of spread, management options, links to management experts, and suggested alternative plants. Fact sheets are available for 40 plant invaders as of March, 1999, an additional 80 are in preparation, and 200 are planned. Alien Plant Invaders of Natural Areas is a project of the Alien Plant Working Group (APWG) which is a subcommittee of the Native Plant Conservation Initiative. The project is supported by volunteers from government, nongovernment organizations, universities, private firms, and other affiliations. Participation is open to anyone interested in helping. Fact sheet authors are needed: please contact the chair through the website.
