From 1981 to 1983, 19 aerial surveys of the study area were conducted at 10 percent sampling intensity over seven Caribou life-cycle phases: winter (March-April); spring (May); calving (June), post-calving (July); August dispersal (August); pre-rut (September); rut (October).

One survey was conducted during each life cycle phase each year except during 1981, when the late winter and spring surveys were not conducted. A mid-June intensive survey (30% coverage) was conducted each year over the coastal lowlands. On intensive surveys, transects extended south of the coast only as far as.
