Addax 1 Government Drive, St. Louis, MO 63110

Addax is an institution located at 1 Government Drive in St. Louis, Missouri, United States. The institution is dedicated to the conservation and preservation of the addax antelope, a species well-suited for desert life. These large antelopes have white haircoats that reflect the desert sun and splayed hooves that make travel on sand easy. Addax rest during the hottest parts of the day and take shelter near bushes and rocks, often digging shallow holes in the cooler earth.

Unfortunately, the addax faces a high risk of extinction in the wild due to overhunting, political insecurity, and habitat disturbance from oil exploration. The Saint Louis Zoo WildCare Institute’s Saharan Wildlife Recovery Center, in partnership with organizations like the Sahara Conservation, is working to save the addax from extinction. The institution also participates in the Zoos and Aquariums Species Survival Plan for the addax, a cooperative breeding program involving multiple zoos.

Visitors to Addax can witness some of the world's most powerful predators, such as lions and tigers, living alongside graceful prey like zebras and giraffes in the natural rocky terrain of Red Rocks. With shady trees and the occasional bird among the mammals, Red Rocks offers a unique and educational experience at the Saint Louis Zoo.
