Many feel like the beauty of the forest is spoiled by the sight of dead and downed trees. They consider the litter unsightly and feel it should be cleaned up. But snags and other woody debris host a concert of life. Insects that live in snags are an important food source in winter. Mosses, lichen, and fungi also serve as dining material. Squirrels and other animals store food inside the cavities. The tree is even useful after it has fallen. It may become a nurse log, hideout, and space for animals to find cool refuge. So instead of cutting down a damaged or dead tree, leave it to nature and enjoy the wildlife show.
