USGS-National Park Service (NPS) Vegetation Characterization Program (VCP) documentation for Carlsbad Caverns National Park and John Muir National Historic Site has been completed and is available on the VCP Web site http://biology.usgs.gov/npsveg/cave/index.html  and http://biology.usgs.gov/npsveg/jomu/index.html. Products include aerial photography - graphic of orthophoto mosaic, and spatial orthophoto data; project report - photointerpretation key, vegetation descriptions, vegetation key, photos of map class, and accuracy assessment; field data - graphic of field plots, plots field database, physical descriptive for plots, and species list for plots; geospatial vegetation information - graphics of vegetation communities, geodatabase, and plot and AA photos; accuracy assessment information - graphic of accuracy assessment points, and contingency matrix; metadata, and a link to NPS information about Carlsbad Caverns National Park and John Muir National Historic Site. The goal of the VCP is to classify and map the vegetation communities of National Parks that have a natural resource component. Complete documentation is currently available for seventy-six park units and two U.S. Fish and Wildlife refuge units. The VCP is managed by the USGS Center for Biological Informatics in cooperation with the NPS Inventory and Monitoring Program. The 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.
