The winter started off fairly easy for wildlife, but the weather has taken a sharp turn toward tough conditions for most wildlife, especially deer.
The winter severity index (WSI) is a measurement gauging the effects of the winter weather on deer survival. The index was developed in the early 1970’s and is calculated by adding the number of days with 18 inches or more of snow on the ground to the number of days when the minimum temperatures were at zero degrees or below. Generally, the severity of the winter is based on the total number of points accumulated over the collection period.
