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.

Project Goal

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.

Recent Events

  • On January 17, 2015, a Catalina Bighorn Sheep Reintroduction Project Volunteer and also an Advisory Committee member, captured photos of ewe ID #454 with a week old lamb. This lamb is the fourth new lamb observed this year. Ewe #454 was relocated to the Catalinas from the Plomosa Mountains in November 2014. This is a good reminder for hikers and recreationists to stay on designated trails, maintain a good distance away from sheep, and to never take dogs into the Bighorn Sheep Management Area. The addition of lambs is critical to the establishment of the herd and their survival could be jeopardized by human-caused disturbance.
