Final report from the SUCR vegetation inventory. Sunset Crater Volcano National Monument (SUCR) Vegetation Mapping Project was initiated in the spring of 1999 as part of and in accordance with the U.S. Geological Survey-National Park Service (USGS-NPS) Vegetation Mapping Program and was completed in the spring of 2004. The Vegetation Mapping Program is administered jointly by the Center for Biological Informatics (CBI), Biological Resources Discipline (BRD) of the USGS, Denver, Colorado, and was initiated as part of the NPS Inventory & Monitoring Program. The primary goal of the Vegetation Mapping Program is to classify, describe, and map vegetation for approximately 250 NPS units.This mapping project was performed by the following organizations under contract to the CBI:• The Remote Sensing and GIS Group (RSGIG), Technical Service Center, Bureau of Reclamation (BOR), Department of Interior, Denver, Colorado• The Colorado Plateau Research Station (CPRS), Southwest Biological Science Center (SBSC), USGS, Flagstaff, Arizona• NatureServe, Boulder, ColoradoSixteen vegetation map classes with five modifiers, three land cover map classes, and six Anderson Level II land-use map classes were used for interpretation of approximately 18,750 acres encompassing the monument (~3,040 acres) and surrounding environs (15,710 acres). Vegetation map classes were determined through extensive field reconnaissance, data collection, and analysis in accordance with the National Vegetation Classification Standard (NVCS). The vegetation map was created from photographic interpretation of 1996, 1:12,000 scale color infrared aerial photographs (0.5 hectare minimum mapping unit). All vegetation and land-use information was then transferred to a GIS database using the latest grayscale USGS digital orthophoto quarter-quads (DOQQs) as the base map and a combination of on-screen digitizing and scanning techniques. Overall thematic map accuracy for the entire mapping effort was assessed at 70.3% using the acceptable error criteria with a Kappa Index of 68.0%. The overall 90% confidence interval is 69.0% to 84.0%.
