About Us

Our region is defined by three distinct landscapes. In the east lie the central and northern Great Plains, primarily the vast mixed- and short-grass prairies. To the west rise the Rocky Mountains and the intermountain areas beyond the Continental Divide, including parts of the sprawling Colorado Plateau and the Great Basin. The northeastern part of the Region contains millions of shallow wetlands known as the “prairie potholes,” which produce a large portion of the continent’s waterfowl.

Our regional office is in Lakewood, Colorado.
