The numbers and distributions of Peary caribou (Rangiier tarandus pearyi) on western Queen Elizabeth Islands, Northwest Territories were determined by aerial surveys based on a standard census strip method. Surveys were flown in March-April and July-August periods in 1972, 1973, and 1974. Comparison of the 1973 and 1974 survevs with those results of a comparable survey in 1961 showed an overall decline of 89% in numbers of caribou between 1961 and 1974. Percentage reduction of caribou numbers from 1961 to 1874 followed a west-cast gradient on the three major islands: Prince Patrick 72%, Melville 87% , and Bathurst 92%. The marked decrease in numbers of caribou is attributed to a combination of high winter mortality in some years and an overall low rate of births and recruitment from 1961 to 1974.
