Zoo Adapts to Climate Change: Desert Sheep Replace Rockies

As Colorado's Front Range experiences extreme heat and air quality warnings, the Denver Zoo is integrating long-term climate adaptation into its master planning. This involves evaluating which species can comfortably tolerate the region's changing environment, a process that has already led to permanent population changes.

Due to increasingly hot temperatures, the zoo has notably swapped its Rocky Mountain Bighorn Sheep for Desert Bighorn Sheep, which are better adapted to arid conditions. Care teams actively monitor daily weather to tailor accommodations for over 3,000 animals across 450 species.

To manage the immediate impacts of the heat, zoo staff have retrofitted exhibits with enhanced shade structures, automated misters, fans, and chilled water. Carnivores receive frozen 'bloodcicles' as a cooling treat, and habitats are designed to allow animals to retreat to cooler indoor spaces.

These proactive measures ensure animal welfare during intense summer conditions. Visitors are also provided relief with water stations, misters, and a designated indoor 'chill zone' to escape the heat, reflecting the zoo's commitment to adapting to climate shifts.
