I recently picked up a copy of the new ADF&G publication "Game Transplants in Alaska" and noticed an interesting section describing the transplant of Dall sheep to Kodiak Island between 1964 and 1967. One ewe was transplanted in 1964, 13 mixed ewes, rams and lambs in 1965, and two additional sheep in 1967. All transplants were from the Kenai Peninsula. The release site was in Uganik Bay and sheep were seen as far away as Barling Bay (about 30 miles). Sheep sightings continued until the mid-1970s. More sheep would have been transplanted, but there was difficulty capturing sheep on the Kenai and a fair number of the captured sheep died. This is the only sheep transplant attempt described in the publication.
In case anyone was wondering, goats first came to Kodiak in 1952, Sitka blacktail deer in 1924.
