In the 2012 President's Budget Request, the National Biological Information Infrastructure (NBII) is terminated. As a result, all resources, databases, tools, and applications within this web site will be removed on January 15, 2012. For more information, please refer to the NBII Program Termination page.
Each year numerous plant and animal species disperse from their natural range to new locations around the world. Many of these non-native, exotic species have colonized the mountain and prairie regions of the United States and become invasive, displacing native plant and animal ecological communities. The consequences of these invasions may be localized or widespread and impacts can range from minor to severe. Invasive species compete with native species, alter ecosystems, and may bring disease not only to native flora and fauna but to humans as well.
State agencies have identified common invasive plants in the Mountain Prairie Region of Kansas, Montana, Nebraska, North Dakota, South Dakota, and Wyoming. For additional information on invasive plant and animal species, including species lists, data, activities, laws, and groups working on invasive species in the United States, visit the Invasive Species Node.
General Invasive Species Information
With enormous environmental, economic, and health costs, invasive species are second only to habitat destruction as a cause of global biodiversity loss.

Click on the button below to open a PDF file of a fact sheet for the 'Invasive Species of the Week'.
The ISSG has launched this 'Invasive Species of the Week' button to raise awareness of the impacts of invasive species on native biodiversity and threatened ecosystems. For information about how to add this button to your own Web site, contact Shyama Pagad (Manager, Species Information Services, IUCN SSC ISSG).
The NBII Program is administered by the Biological Informatics Program of the U.S. Geological Survey
