Alien Plants Ranking System - By National Park Service, Ripon College, University of Minnesota, and the U.S. Geological Survey. A computer system (available for download) to help land managers make difficult decisions about invasive nonnative plants; including comparison of innocuous species with invasive ones, and identification of potentially invasive plants. The system also addresses the feasibility of control of each species, enabling the manager to weigh the costs of control against the level of impact. From the Northern Prairie Wildlife Research Center/U.S. Geological Survey. [Western Region]

Colorado Weed Mapping - Links to maps that depict the statewide distribution and abundance of 20 selected noxious weed species in the state. From the Colorado Department of Agriculture. [Colorado]

Colorado Weed Mapping Program - Weed mapping is needed for complete and effective planning and execution of an integrated weed management plan. The mapping methods (protocols) suggested here are only a few of many ways to get required weed data into a universally useable database. From the Colorado Department of Agriculture. [Colorado]

Handbook for Ranking Exotic Plants for Management and Control - By Ronald D. Hiebert. Detailed explanation of a system developed for resource managers to sort exotic plants within a park according to the likelihood of a particular plant becoming a pest. The rationale of the system is described including supporting research. A thorough explanation of system application, with examples, is included. From the National Park Service. [Western Region]

Interactive map of Idaho noxious weeds. - Map with information on weeds, watershed, and topography. Need to zoom in on map to visualize information. From the Idaho Department of Agriculture. [Idaho]

Invasive and Exotic Weeds - By G. Keith Douce, David J. Moorhead, and Charles T. Bargeron. A list of over 400 invasive weeds, alphabetical by scientific name, with links to pages with photos and descriptive information. A joint project of The University of Georgia's Bugwood Network, USDA Forest Service and USDA APHIS PPQ. From the USDA Animal and Plant Health inspection Service (APHIS), US Forest Service, and The University of Georgia. [Western Region]

Invasive Plant Prevention Guidelines - By Janet Clark. This introduction to the ecological basis of invasive plant management provides guidelines for prevention and for developing weed management areas. From the Center for Invasive Plant Management, Montana State University. [Western Region]

Invasive Weed Identification for Nevada - Color brochure with detailed photos and descriptions of weeds, habitat, and management, 86 pages. From the University of Nevada-Reno, Cooperative Extension. (pdf, 3506K) [Nevada]

Mapping Invasive Plants - By Kathryn Thomas. Information on contributions of field observations on invasive plant distribution and abundance for inclusion into a regional database. From the Geological Survey. [Southwest Region]

Nevada Weed Mapping Activities - Mapping locations of noxious weeds is a vital part of the battle to control these pests; Federal, state and local government agencies, as well as interested private organizations and individuals, contribute to the weed mapping effort. From the Nevada Department of Agriculture. [Nevada]

Pasture Weed Management - By J. J. Mullahey and B. J. Brecke. Prevention, detection and control of pasture weeds. From the Florida Cooperative Extension Service. [Western Region]

Predicting Invasions of Nonindigenous Plants and Plant Pests (2002) - Biological invasions of nonindigenous plant pests—plants, pathogens, and insects—are serious threats to the rural, urban, and natural ecosystems of the United States. In the agricultural setting, hundreds of millions of dollars are spent each year on pesticides and herbicides to control pests. This site provides full-text access chapter by chapter to this book, which is over 200 pages long. From the Board on Agriculture and Natural Resources (BANR), National Academy Press. [Western Region]

Reporting Weeds - How to participate in Colorado's weed mapping effort. From the Colorado Department of Agriculture. [Colorado]

Sketch Mapping - Mapping weed problems; large and small scale. Examples of weed locations on a hand drawn map, topographical map or aerial photograph. From the Colorado Department of Agriculture. [Western Region]

Southwest Exotic Mapping Program - The Southwest Exotic Mapping Program (SWEMP) is a USGS Colorado Plateau Field Station (CPFS) program that coordinates the compilation of a regional database of exotic plant distributions for the southwest (Arizona, New Mexico and adjacent areas of adjoining states) and creates maps for those distributions. From the Northern Arizona University and the US Geological Survey. [Southwest Region]

Southwest Exotic Plant Information Clearinghouse (SWEPIC) - 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. From the US Geological Survey and Northern Arizona University. [Southwest Region]

USDA, APHIS, Qualitative Risk Assessment for potential Federal noxious weeds - Template - Proposed template to provide information about a plant species suspected of being “a pest of potential economic importance to the area endangered thereby" and that should be listed as a noxious weed. Word document. From the USDA Animal and Plant Health inspection Service (APHIS). [Western Region]

Weed Inventory Basics - Basic information on mapping weeds. From the Colorado Department of Agriculture. [Western Region]
