Some of the nation’s greatest rivers rise in the Region including the Missouri, Colorado, and Platte rivers. The fish and wildlife that make their home on the Region’s prairies and in its mountains are among the nation’s most iconic species: grizzly bear, gray wolf, the American bison, and cutthroat trout.
People, too, live here and are an active presence on the land. The Region includes 40 Indian Tribes, many of whom manage large land holdings, as do other federal agencies such as the Department of Defense. Energy development, agricultural trends and urbanization all exert influences on the Region’s landscapes.
