The Southwest Exotic Plant Information Clearinghouse is a cooperative effort among the U.S. Geological Survey, the National Park Service and Northern Arizona University to organize comprehensive information on exotic plant species in the southwest on one web location. SWEPIC serves to help all people and organizations committed to protecting the ecological and economic values of southwest resources from degradation from harmful non-native weeds. The goal of SWEPIC is to provide reliable and organized information on the distribution and ecology of these weeds in the southwest, with an emphasis on forests, rangelands, and other natural areas. Please contact us if you have information or comments that should be included in SWEPIC (SWEPIC Team).
