Winter Severity Index (WSI) for White-tailed Deer

The Winter Severity Index (WSI)is a general measure of winter
conditions based on the premisethat prolonged cold temperaturesand
deep snow can reduce overwinter survival of white-taileddeer. In
Minnesota the WSI iscalculated by accumulating a pointfor each day
with an ambienttemperature = 15 inches. End-of-season values 180
indicate a severe winter.
