Species Abstracts of Highly Disruptive Exotic Plants

The invasion of non-indigenous plants has been recognized by park managers and natural resource scientists as one of the most serious threats to the integrity of natural systems, rare communities and species, and animal habitat. In a collaborative and on-going project, NBS, the National Park Service, and academic scientists are collecting the data necessary (1) to determine distribution and abundance of non-indigenous plants in national parks in the central United States, and (2) to rank the plants with respect to their invasiveness, potential to disrupt the ecosystem, and ability to be controlled. This information will be used to develop realistic management plans for non-indigenous plant species at each park.

The pages that follow include the ranking system, developed by Ronald Hiebert and James Stubbendiek, and comprehensive abstracts for each species that was ranked as highly disruptive in the areas that have been surveyed. The abstracts contain information on the taxonomy, ecology, distribution within the park, control options, and a literature review for each plant.

Currently, field work is continuing at Theodore Roosevelt National Park and is planned for Wind Cave National Park and Knife River Indian Villages. If you have comments or questions regarding this project, you may direct them to Diane Larson, Research Biologist, Northern Prairie Science Center.

All abstracts included here were initially written by Chuck Butterfield and edited by James Stubbendieck for Pipestone National Monument (PIPE), with the exception of the abstracts on Cynoglossum, Centaurea, and Lythrum which were written by Julie Stumpf and edited by James Stubbendieck. For the Scotts Bluff (SCBL) and Effigy Mounds (EFMO) National Monuments reports, abstracts of plants that had also occurred at PIPE were simply modified to reflect that parks population numbers and rankings. Thus, there will be quite a lot of repetition in abstracts between the park's with only ranking and population numbers changed.
