Trees (Smithsonian's Natural World Series)

More than 80,000 species of trees today cover a full 30 percent of the earth's land mass and have dominated the earth for over 300 million years. They are the largest organisms that have ever lived, with some species outweighing the largest whales ten to one. In this richly illustrated overview, Roland Ennos examines trees' history, explains their mechanics, and assesses their future.
