Today, only the black bear is known to exist in Colorado. Although we do not know exactly how many black bears live in Colorado, population estimates range from 8,000 to 12,000 bears. A black bear may live 20 years in the wild, although very few do, and up to 25-30 years in captivity. Black bears are very agile, can run in bursts up to 35 mph and can run up or down hills quickly and easily. Their short, curved claws help them to climb trees.
Black bears are strong swimmers.
Threats to black bears include accidents, disease, motor vehicles and starvation. Natural enemies include other bears and mountain lions. Prior to 1935, there was unlimited hunting of black bears. The designation of bears as game animals in 1935 provided for their management and protection. Current hunting regulations protect cubs and females with cubs and prohibit the use of dogs and baiting.
