Pruitt, W.O., Jr. 1981. Application of the Värriö Snow Index to Overwintering North American Barren Ground Caribou (Rangifer tarandus arcticus). Canadian Field-Naturalist 95 (3): 363-365.

The Värriö Snow Index (VSI) that I derived to model the overwintering activity and movements of feral and domesticated Reindeer in northeastern Finland was used successfully to model the wintering activity and movements of wild North American Barren-ground Caribou (Rangifer tarandus arcticus). This index is a potentially useful tool for determining nivally suitable areas for Caribou overwintering.

Key Words: Caribou, Reindeer, snow ecology, Mammalia: Cervidae, winter activity.
