The purpose of the Georgia EPPC is to focus attention on: 1. the adverse effects exotic pest plants have on the diversity of Georgia's native plants and animals; 2. the use of exotic pest plant management to prevent habitat loss; 3. the socioeconomic impacts of these plants; 4. changes in the seriousness of the different exotic pest plants over time; 5. the need to exchange information which helps land owners and managers set priorities for exotic pest plant management.

The purpose of the Mid-Atlantic Exotic Pest Plant Council (MA-EPPC) is to address the problem of invasive exotic plants and their threat to the Mid-Atlantic region's economy, environment, and human health by providing leadership, facilitating information development and exchange, and coordinating regional efforts. Members of the Mid-Atlantic EPPC represent Delaware, Maryland, New Jersey, Pennsylvania, Virginia, West Virginia, and the District of Columbia.

United Nations Environment Programme - World Conservation Monitoring Centre. The UNEP World Conservation Monitoring Centre provides information for policy and action to conserve the living world. Our programmes concentrate on species, forests, protected areas, marine, mountains and freshwaters; plus habitats affected by climate change such as polar regions. We also address the relationship between trade and the environment and the wider aspects of biodiversity assessment.

All weeds are not of equal importance for management. The focus of this list is on exotic species that are highly invasive in natural systems. Those species that are of a concern in agricultural situations, but do not pose a threat to rangelands, forestlands and wetlands have not been included. Many annual forbs have not been included. Exotic species typically used in range restoration which are known to be invasive have not been included. Invasive annual grasses which disrupt natural ecosystem function have been included.

The Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) was established through a Memorandum of Understanding signed by agency leadership in August 1994. FICMNEW represents an unprecedented formal partnership between 16 federal agencies with direct invasive plant management and regulatory responsibilities spanning across the United States and territories. During monthly open meetings, FICMNEW members interact on important national and regional invasive plant issues and share information with various public and private organizations participating with the federal sector to address invasive plant issues.

The Invasive Plants Association of Wisconsin seeks to provide information and resources to combat the spread of noxious, invasive plants in Wisconsin.

Invasive Species: any species of insects, animals, plants and pathogens, including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that ecosystem; and whose introduction does or is likely to cause economic or environmental harm or harm to human health
