The Intermountain Region of the Forest Service consists 13 National Forests and one National Grassland encompassing nearly 34-million acres of National Forest System land or 17% of the Forest Service lands of the United States. The region is administered by Forest Supervisors in Utah, Nevada, southern Idaho and western Wyoming.

The Intermountain Regional Office in Ogden, Utah provides administrative oversight and support to 12 National Forests and one National Grassland in Utah, Nevada, western Wyoming, and southern and central Idaho. The National Forest Supervisor's Offices are the headquarters for forest activities and provide oversight and support to the Ranger District offices within the forest boundaries. Ranger Districts are the units that directly manage the national forests and grasslands. Types of management that occur on each district vary significantly. Some districts manage ski areas, wilderness areas, wild and scenic rivers, and resource management programs and extensive recreational uses. Four major geographic provinces come together to form the Intermountain West. They include the Great Basin, Colorado Plateau, Middle Rocky Mountains and the Northern Rocky Mountains. These provinces are the reason for the tremendous diversity of landscapes and ecosystems within the Intermountain Region.
