Catalina Bighorn Sheep Reintroduction Project
This web page includes joint updates from the Arizona Game and Fish Department and the Catalina Bighorn Advisory Committee on the Catalina Bighorn Sheep Reintroduction Project.
The goal of the project is to establish a self-sustaining population of bighorn sheep in the Catalina Mountains that coexists with resident predators without administrative intervention. Bighorn sheep are being reintroduced because the Catalina Mountains are a part of their historical range; the project is trying to restore them to a natural ecosystem that they were an important part of for thousands of years. As long as one of its key pieces—bighorn sheep--is missing, the ecosystem is in some ways incomplete.
Questions and Answers about the Project
Mortality of Ewe #37444. The carcass of ewe #37444 was discovered by Arizona Game and Fish Department (Department) personnel on the afternoon of August 24. The GPS component of her collar had not uploaded her location since August 21, and it did not send a mortality signal. However, Department staff had been aware of her decreased movement patterns over the preceding days and surmised she was likely sick. There were no signs of predation. Samples were collected from the carcass for disease testing.
