The mission of the Connecticut Invasive Plant Working Group is to gather and convey information on the presence, distribution, ecological impacts, and management of invasive species; to promote uses of native or non-invasive ornamental alternatives throughout Connecticut; and to work cooperatively with researchers, conservation organizations, government agencies, green industries, and the general public to identify and manage invasive species pro-actively and effectively.

The mission of the Florida Exotic Pest Plant Council is to support the management of invasive exotic plants in Florida's natural areas by providing a forum for the exchange of scientific, educational and technical information.

Invasive plants and their biology, impact and control options by David J. White and Erich Haber. The problem of plants invading natural areas in North America, especially species originating in Eurasia, dates back to the earliest days of European settlement. Canadian Wildlife Service (CWS), part of Environment Canada, handles wildlife matters that are the responsibility of the federal government

Invasive species displace native species, disrupt ecosystems, and affect citizens livelihoods and quality of life. Learn how you can help keep them in check.

The Invasive Plants website contains information on invasive plants, their impact on native species, and their control (particularly biological control). The web pages focus on work conducted by students and staff of the Ecology and Management of Invasive Plants Program, directed by Bernd Blossey, at Cornell University. The majority of our work concerns species and ecosystems in northeastern North America, but most species we work with are distributed widely through North America.

A searchable database providing citations and summaries of literature pertinent to controlling invasive exotic plants. This annotated bibliography contains references on control of exotic plant species that occur in the Great Plains. You may search on either the species of interest or on the type of control measure. Complete citations are provided, as well as summaries describing the control technique and whether it was successful. These summaries are not meant to give detailed instructions; readers are encouraged to obtain the original article and talk with the investigators before attempting the control measure.

Forestry Images: Forest Health, Natural Resources and Silviculture Photos with pictures of insects, diseases, trees, plants, weeds, ecosystems, fire, ecology, other pests and wildlife.

Invasive Weeds of North Dakota and Weeds of Concern as well as Thistles of North Dakota. This is an Educational Site for all ages.

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.
