About the Area

As part of the National Forest System, the Rocky Mountain Region (Region 2) enjoys a proud heritage in the Forest Service. The Shoshone National Forest in Wyoming and the White River National Forest in Colorado are among the first National Forests Congress created from the original Forest Reserves. The Region, headquartered in Lakewood, Colorado, comprises 17 national forests and 7 national grasslands. Region 2 encompasses national forests and grasslands in Colorado, Kansas, Nebraska, and most of South Dakota and Wyoming.

The US Forest Service Rocky Mountain Region has formally identified four overarching themes as emphasis areas on which to focus strategic long-term efforts to preserve their special values: Forest and Grassland Health, Recreation, Water and Public Service. Forests and Grasslands continue to hold in trust America's resources- timber, wildlife, water, range, recreation - to ensure their availability today and tomorrow.
