The VCP is managed by the USGS Center for Biological Informatics in cooperation with the NPS Inventory and Monitoring Program. The USGS Vegetation Characterization effort includes the management and upkeep of the VCP protocols, Web-based access to the standards, and the Web-based access to NPS Vegetation Characterization program finished products.
