描述
Old-time New England foresters coined the term "wolf tree" for trees they saw as having the ability to "eat" the sun and nutrients and prevent the growth of other trees. Today, however, we understand how wolf trees benefit wildlife. Join Aurora and Orion as they search for a wolf tree in the 3500-acre forest managed by Harvard University near Petersham, Massachusetts, looking for such clues as a large trunk, low branches, wildlife activity, and nearby smaller trees.
