The USGS Biological Resources Division in cooperation with the Inventory and Monitoring Program of the National Park Service has initiated a multi-year project to classify, describe, and map vegetation for 250 national parks. As a contractor under this program, the Bureau of Reclamation’s Remote Sensing and Geographic Information Group with assistance from The Nature Conservancy has classified and mapped the vegetation occurring in and around Theodore Roosevelt National Park. The Park has three units with the North Unit near Watford City and the South Unit near Medora , North Dakota. The third unit lies between the North and South units and consists of the historic Elkhorn Ranch. Twenty-nine vegetation (land-cover) map classes and ten Anderson Level II land-use classes were used for interpretation of approximately 369,000 acres encompassing the Park (~ 70,200 acres) and surrounding environs (~ 298,800 acres). The interpreted data was digitally transferred into a Geographic Information Systems database.Vegetation map classes were determined through extensive field reconnaissance, data collection, and analysis in accordance with the National Vegetation Classification System. The vegetation map was created from photographic interpretation of 1996, 1:12,000 scale color aerial photograph enlargements (0.5 hectare minimum mapping unit). All vegetation and land-use information was then transferred to the latest grayscale USGS digital orthophoto quarter-quads using a combination of on-screen digitizing and scanning techniques. Arc/Info™ (ESRI, Inc.) software was used throughout the project for digitizing, scanning, transforming, registering, and plotting the interpreted data. Overall thematic map accuracy for the entire mapping effort was assessed at 74.3 % with a Kappa Index of 71.3 %. The overall 90% confidence interval is 70.3 % to 78.3 %.
