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.
