Rocky Mountain Bighorn Sheep
Rocky Mountain Bighorn Sheep

​​​​​​​Majestic and agile, the Rocky Mountain bighorn sheep is a prominent figure on the steep and jagged walls of Colorado's canyons. But, despite its prominence and grandeur, the bighorn was near extinction at the turn of the century. Diseases introduced through European livestock and overhunting had decimated populations throughout the West, and only a small number of the native sheep remained in Colorado in the early 1900s.

Colorado Parks and Wildlife (CPW), in cooperation with the Rocky Mountain Bighorn Society, has spent decades rebuilding sheep populations through aggressive trapping and relocation efforts. CPW conducted the first sheep transplants in the 1940s, including planting bighorns between Georgetown and Silver Plume. Known simply as the "Georgetown Herd," this population of 250-350 sheep is one of the largest herds in the state and has become one of the most popular sheep viewing sites in the nation. 

Since Colorado's restoration efforts began, CPW has completed more than 100 bighorn sheep transplants, most of which took place in the 1970s and 1980s. Gore Canyon in northwest Colorado is one of the most recent transplant locations. CPW closely monitors bighorn sheep herds and maintains healthy populations through controlled hunting and ongoing trapping and relocation. Thanks to decades of dedicated conservation efforts, Colorado's iconic bighorn sheep are once again abundant with an estimated statewide population of 7,000 animals.​​​
