Bighorn sheep are common in American Indian rock art, an indication of their presence and prominence in indigenous cultures. Accounts from European explorers in the late 1600s estimate that more than two million desert bighorn once roamed the southwest. However, by the late 1800s bighorn sheep had disappeared or declined in many areas. Extremely vulnerable to diseases from European livestock, herd after herd of wild sheep were decimated by pathogens like scabies (an ear mite) and anthrax (a bacterial disease) introduced by domestic sheep. Bighorns were also killed by early explorers, settlers, and trophy hunters.
Increased human activity and development continue to threaten the desert bighorn sheep. For the remaining herds to survive, management may always be necessary. Protecting wild lands is key to the survival of these amazing animals, and The Colorado Division of Wildlife in partnership with Colorado National Monument will continue to play a large role in these ongoing efforts.
