Population Dynamics of the Mackenzie Delta Reindeer Herd, 1938-1958
Analyzes fluctuations in the size of both government- and Eskimo-owned herds of Rangifer tarandus in the Reindeer Grazing Preserve of northern Mackenzie District. Each of the six Eskimo-owned herds increased in numbers for a few years, then declined and ultimately, except one, was returned to the nu...
