USNVC overview

The U.S. National Vegetation Classification (NVC) is a standardized, hierarchical classification system for vegetation in the United States. (It is aptly named.) The NVC standards were developed by a partnership of agencies (e.g., USDA Forest Service and US Geological Survey), professional organizations (e.g., the Ecological Society of America), and non-profits (e.g., NatureServe). The full NVC database, which can be downloaded from http://www1.usgs.gov/csas/nvcs_data/USNVCFullDownload.zip, contains 18 tables with information on 8,192 vegetation categories, ranging in scope from seven very broad Classes to >4,000 highly refined Associations.
