This vegetation classification and mapping effort encompasses 167,148 ha(413,031 acres ) within the San Luis Valley, west of the Sangre de Cristo Mountains in south central Colorado. The mapping boundary is made up of several management units from a variety of government and private agencies (and a small amount of private property).

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 Natural Resource Publication series addresses natural resource topics that are of interest and applicability to a broad readership in the National Park Service and to others in the management of natural resources, including the scientific community, the public, and the NPS conservation and environmental constituencies. Manuscripts are peer-reviewed to ensure that the information is scientifically credible, technically accurate, appropriately written for the intended audience, and is designed and published in a professional manner.

Hubbell Trading Post National Historic Site (HUTR) covers approximately 65 ha (160 acres) in northeastern Arizona, and lies wholly within the borders of the Navajo Nation. The vegetation found at HUTR consists of approximately 184 species of vascular plants, representing 48 families, in a limited set of communities. This mapping project is part of the National Park Service's National Inventory and Monitoring (I&M) Program, and has been designed to provide core, or “baseline” information that park managers need to effectively manage and protect park resources.
