Northern Great Plains

Stretching from the foothills of the Rockies into the badlands of the Dakotas and Nebraska, the Northern Great Plains cover over 180 million acres. The landscape is characterized by expansive grasslands supporting a unique assemblage of wildlife adapted to require little or no disturbance to sustain their populations. 

Rocky Mountain Rangelands

The Rocky Mountain Rangelands encompasses the Intermountain West, including Colorado, Idaho, Montana, Nevada, Utah and Wyoming. The region supports a unique assemblage of wildlife adapted to the harsh climate that often require large, open spaces to sustain their populations. Irrigated agricultural lands provide habitat for suites of waterfowl, waterbirds and shorebirds during their migration and breeding season. The relative arid nature of the region has also led to endemic fish found only in small river systems.
