The gray wolf is kept in parks and zoos in Colorado, but there are no wolves in the wild. Gray wolves were hunted for attacking livestock and have not existed in the wild within the state since the late 1930s.
There has been interest in restoring the gray wolf to Colorado, but owners of livestock have resisted the movement. Wolves have been restored to several other states, such as Wyoming and New Mexico, and it is thought to be only a matter of time before they naturally migrate back to Colorado. Gray wolves hunt large game species, such as elk, and are useful as a check on the population of such game.
