Animal and Plant Health Inspection Service – The Animal and Plant Health Inspection Service (APHIS) is responsible for protecting and promoting United States agricultural health, administering the Animal Welfare Act, and carrying out wildlife damage management activities.
Aquatic Ecosystem Restoration Foundation – A nonprofit, tax-exempt foundation created to conduct and support applied research in the management of aquatic pest species, with a focus on nuisance vegetation. The corporation supports research for the control of aquatic weed species and exotic plants such as Eurasian water milfoil, hydrilla, water hyacinth, purple loosestrife, and other aquatic weeds found in lakes, ponds, reservoirs, rivers and streams.
Ecology and Biology of Invasive Plants Program – The Invasive Plants website contains information on invasive plants, their impact on native species, and their control (particularly biological control).
North American Lake Management Society – The purpose of the Society is to assist in the management of aquatic vegetation, to provide for the scientific and educational advancement of members, to encourage scientific research in all facets of aquatic plant management, to promote an exchange of information among members, and to extend and develop public understanding in the discipline. The North American Lake Management Society’s mission is to forge partnerships among citizens, scientists, and professionals to foster the management and protection of lakes and reservoirs for today and tomorrow.
United States Geological Survey Non-indigenous Aquatic Plant Distribution Information – Diverse in form and habit, many aquatic species have become established in the United States outside of their natural range. Introduced intentionally or escaping from cultivation, non-indigenous plants can colonize aquatic communities where they compete with and often displace native species. Hydrilla (Hydrilla verticillata), water-hyacinth (Eichhornia crassipes) and Eurasian water milfoil (Myriophyllum spicatum) are examples well known for their ability to alter physical and biological functions of aquatic systems.
United States Department of Agriculture – Exotic and Invasive Weed Research Unit – As exotic plants spread rapidly across North America and dominate new areas, they displace desirable plants that provide valuable forage for livestock and wildlife, eliminating critical habitats and affect other natural resources (including water) that are important for threatened and endangered species as well as agricultural production.
Weed Research and Information Center – An interdisciplinary collaboration that fosters research in weed management and facilitates distribution of associated knowledge for the benefit of agriculture and for the preservation of natural resources.
Weed Science Society of America – The Society was established to encourage and promote the development of knowledge concerning weeds and their impact on the environment. The society membership currently consists of approximately 2,000 scientists worldwide. The Society publishes two journals, Weed Science and Weed Technology.
