How many acres is the Horse Range that was established by Congress in Bighorn Canyon National Recreation Area?
Pryor Mountains Wild Horse Range The Pryor Mountains Wild Horse Range is a refuge for a historically significant herd of free-roaming Mustangs, feral horses colloquially called "wild horses", located in the Pryor Mountains of Montana and Wyoming in the United States. The range has an area of 39650 acre and was established in 1968 along the Montana–Wyoming border as the first protected refuge dedicated exclusively for Mustangs. It was the second feral horse refuge in the United States. About a quarter of the refuge lies within the Bighorn Canyon National Recreation Area. A group of federal agencies, led by the Bureau of Land Management, administers the range.
Little Missouri National Grassland Little Missouri National Grassland is a National Grassland located in western North Dakota, USA. At 1028051 acres , it is the largest grassland in the country. Enclaved within its borders is Theodore Roosevelt National Park, which is managed by the National Park Service (and therefore not included in the preceding statistics). The Little Missouri National Grassland was once a part of the Custer National Forest, but is now a part of the Dakota Prairie Grasslands, a National Forest unit consisting entirely of National Grasslands. A predominant feature of the grassland is colorful and beautiful badlands, a rugged terrain extensively eroded by wind and water. It is a mixed grass prairie, meaning it has both long and short grass.
