Asterisk indicates significant association at P < areas and Caribou were digging through it to the herb layer. In both winter surveys, none of the association coefficients were significant, indicating that Caribou were found throughout the vegetation types in pro- portion to their occurrence in the transects (Figure 3). In both years. Caribou wintered in the northern half of the park along the Stikine River, with the major concentration occurring along the northeastern edge of the Spatsizi Plateau. The largest Caribou herds (68 in 1976 and 208 in 1977) were seen in the sub-alpine zone on the same slope. In March 1976, flights were restricted to the main park area and the immediately adjacent land. In 1977, we extended the survey into the south of Tatlatui Park, but we saw no Caribou tracks. We also surveyed north of the Stikine River alongthe McBride, Turnagain (north of map), Tucho, and Pitman Rivers. Caribou tracks were numerous along the McBride and Turnagain Rivers, although we saw only three small groups of Caribou along the Turnagain River. Therefore, in March, Caribou showed no preference for any vegetation type, but they did concentrate their activities in the northern portion of the park. In late May 1976, snow had melted from most of the area below the tree line in the north and centre of the study area; rain fell intermittently and temperatures were around +5°C. However, snow still covered the area south of Caribou Hidecampon the upper Stikine River, in the southeast of the study area. This area is higher and colder, and snow showers were frequent. Caribou were scattered in small groups throughout the north, centre, and east of the area (Figure 4), and, unlike the March survey
