| Objective |
To transplant Stone's sheep from the north side to the south side of the Peace Arm (Williston Reservoir) in order to establish a viable sheep population, and thus increase the range of Stone's sheep in the watershed. This was the first transplant of Stone's sheep in North America.

| Study area |
Source sheep: Various locations from the north side of the Peace Arm, Williston Reservoir.
Release sites: Mt. Frank Roy and Mt. Monteith , south side of Peace Arm. |
| Methods |
Twenty-eight Stone's sheep were captured, sedated, and transported (via helicopter) to their release sites. Ten sheep were fitted with VHF radio-collars and monitored monthly by fixed-wing aircraft for 4 years to determine seasonal habitat use and movements after their release. Four sheep from the source herds were also radio-collared and monitored to compare seasonal habitat use and movements with the transplanted group. Five aerial inventories of sheep on the south side were conducted by Bell 206 helicopter to determine their population size, demographics (age/sex composition), and distribution. |
