Includes bibliographical references. "Aerial surveys by the Canadian Wildlife Service in 1967 and 1963 produced an estimate of 385,000 barren-ground caribou for the four major populations on mainland Canada. A direct comparison of this estimate to results of the 1955 aerial survey of the same populations suggests an increase of approximately 50 per cent during the 12 years between surveys"--Abstract.
