The Southwest Exotic Plant Information Clearinghouse is a cooperative effort among the USGS, the National Park Service and Northern Arizona University to organize comprehensive information on exotic plant species in the southwest on one web location. This site provides information on the distribution and ecology of native and exotic weeds in the southwest by providing links to downloadable weed distribution maps as well as reference lists of weeds organized by scientific name, common name, or geographic region.
