Hagerman Fossil Beds National Monument (HAFO) encompasses approximately 4,351 acres in the Snake River canyon in central Idaho. HAFO is located approximately 35 miles west of Twin Falls, Idaho and 100 miles east of Boise. This unique terrain supports approximately 380 species of vascular plants and includes examples of native plant communities indigenous to this area. The park consists of two areas located on opposite sides of the Snake River. Approximately 60 acres is located on a relatively flat area east of the river (future monument's museum and interpretive center) with the balance of the monument located west of the river. To better understand the distribution of the plant assemblages located on these sites, the National Park Service (NPS) Upper Columbia Basin's Inventory and Monitoring Network (UCBN) started a vegetation mapping and classification effort at HAFO in 2006.

The Northern Colorado Plateau Inventory and Monitoring Network worked with the support of the U.S. Geological Survey - National Park Service Vegetation Mapping Program to describe and map vegetation at Fossil Butte National Monument (FOBU). This collaborative effort involved many project partners, particularly the FOBU superintendent and natural resources staff, the Rocky Mountain Mapping Center of the U.S. Geological Survey, the Western Region office of NatureServe, engineering-environmental Management, Inc., and their cooperators.

The Northern Colorado Plateau Inventory and Monitoring Network cooperated with the U.S. Geological Survey - National Park Service Vegetation Mapping Program to describe and map vegetation at Cedar Breaks National Monument (CEBR). This collaborative effort involved many project partners, particularly the Rocky Mountain Geographic Science Center of the U.S. Geological Survey, the Western Region office of NatureServe, engineering-environmental Management, Inc., and their cooperators.

The goal of the study was to accurately map and classify at least to the alliance level of the USNVC, the vegetation in Appomattox Court House National Historical Park, Booker T. Washington National Monument, Colonial National Historical Park, Fredericksburg and Spotsylvania National Military Park, George Washington Birthplace National Monument, Petersburg National Battlefield, and Richmond National Battlefield Park. The classification used to map these parks was developed regionally, using quantitative data that was collected from all seven park units and combined with existing data from throughout the Mid-Atlantic Piedmont and Coastal Plain.
