The U.S. Forest Service's Southern Region Task Force for Assessing Nonnative Invasive Species (NNIS) was assembled to prioritize NNIS that pose the highest threats to forests and grassland ecosystems in the South. The Task Force collaboratively compiled a list (based on multiple existing databases and surveys of Forest Service regional staff) of the most potentially damaging invasive species. Existing risk assessments for these NNIS were assembled for ranking priority threats. Through this process, three databases were compiled of NNIS that damage, or have the potential to damage, forest interiors, margins, openings, roadsides, waterways, and wetlands as well as grasslands and special embedded habitats. These three databases, hosted by the Center for Invasive Species and Ecosystem Health at the University of Georgia, are accessible at http://www.invasive.org/south/. Since public release of the Web site at the beginning of the year, there have been nearly 26,000 hits, a figure that suggests strong public interest in the issue of managing invasive species.
