Ecology is the study of plants and animals and their relationship with the environment. Winter ecology is simply studying the relationship of plants and animals in the winter. Signs of wildlife in winter are sparse and often subtle, but to the trained eye, they tell a rich story of survival. At the Vermont Institute of Natural Science in Woodstock, the study of our natural environment continues through Vermont's winter months. Teachers come to the Institute in winter to learn how to use outdoor activities to help their students develop a better understanding of their environment. We spent some time recently at the Institute with a group of teachers to learn a little about the world around us in winter.
