National Invasive Species Council

Although the National Invasive Species Council staff would like to respond to information requests regarding invasive species, it is not possible for us to respond to all such inquiries. The large numbers of invasive species alone prevent us from maintaining detailed information on specific species. In addition, determining the invasiveness of a species depends on a number of local factors, including type of habitat. Specific information may be obtained by contacting local and state agencies, organizations, libraries, universities and colleges (see the Agencies and Organizations list and the Frequently Asked Questions section).
