The World of Northern Evergreens

E. C. Pielou, a professional biologist, has the gift of being able to convey in everyday language her knowledge of the fascinating things to be seen in the evergreen forests of the northern United States and Canada and on the major mountain ranges of the eastern and western United States. She discusses the distinctive features of various evergreen trees, providing information on how to recognize different kinds; describes how they reproduce and grow; and assesses the impact of fire, wind, snow, ice, clear-cutting, and air pollution.
