The Plots Database is a set of software tools developed under contract from the USGS Center for Biological Informatics by The Nature Conservancy for field data collection and analysis. It is available for downloading. This software may potentially be used as the tool for aiding in the expansion and refinement of the lower levels of the National Vegetation Classification Standard. (Future plans include making this software available as an interactive web based program.)
