As a scientific standard, and as a tool for both federal and nonfederal agencies, organizations, and scientists, the U.S. National Vegetation Classification (USNVC) is becoming an important ecological vegetation classification that helps provide basic and consistent information on the status and trends of the nation’s vegetation and ecosystems. It is supported by the Federal Geographic Data Committee (FGDC) Vegetation Subcommittee (comprised of participating federal agencies), NatureServe, and the Ecological Society of America (ESA). Together these partners have used their scientific and applied expertise to put in place a flexible and innovative data standard for vegetation classification, using the EcoVeg approach that forms the scientific basis for the USNVC. We present the results of a workshop in Anchorage Alaska, Nov. 7-9, 2017, in which the participants were organized into three teams—Arctic & Alpine, Boreal, and Coastal Pacific (hereafter Coastal)—to review existing macrogroups and groups and revise as needed based on expert knowledge, maps, and available publications.
