Family Anttlocapridae—Pronghorn Antilocapra americana Pronghorn The pronghorn originally ranged over much of western North America, in open re- gions such as the Great Plains, the Great Basin, the Columbia Plateau, and interior val- leys of California. Antilocapra americana is the sole living representative of a family autochthonous in the North American grass- land. The original range in Colorado was statewide in suitable habitats, including areas of short-grass prairie, open shrublands, and mountain parks, at elevations to over 10,000 feet. Pronghorn were abundant in Colorado in the mid-Nineteenth Century (see G. B. Grin- nell, 1929; Gary, 1911:58; Warren, 1942:290). Seemingly boundless herds were greatly re- duced by market-hunters. Closed seasons were established in 1885, and market-hunting was outlawed in 1893. From 1899 until 1944 there was no open season on pronghorn. Pop- ulations continued to decline for a time, how- ever, because enforcement was inadequate and in 1918 fewer than 1000 pronghorn were thought to exist in Colorado. In 1921 the Colorado Antelope Refuge was established near Norfolk in northeastern Larimer County. Additional refuges were established in eastern Colorado in 1937 and 1941. Antelope restora- tion over parts of the former range, aided by an extensive program of transplants, began in 1939
