TREES IN CANADA is a guide to the many tree species, both native and introduced, that are found throughout Canada and the northern United States. It evolved from the popular Native Trees of Canada, which for 8 editions and over 75 years provided information on trees in nontechnical language and in an easy-to-use format. The last edition, published in 1979, gave only passing mention to non-native or introduced trees. Trees in Canada includes descriptions of introduced species that are commonly planted or naturalized. The text for the new edition has been reviewed by forest science specialists across Canada and in the United States. A Reader's Guide shows how the book is organized and explains technical terms.The author has ingeniously organized the more than 300 tree species into 12 groups based mainly on leaf shape and arrangement along the twig. The features that define the 12 groups require little botanical knowledge to recognize and are easily observed. An identification key inside the front and back covers comprises an icon (a stylized drawing) for each group, a statement of the group's essentialfeatures, and a numbered thumb tab, which allows rapid entry to the group. Dichotomous keys for the groups and large genera and winter keys for broadleaf trees and deciduous conifers are also provided. The comprehensive and well-researched text of Trees in Canada is complemented by nearly 600 color photographs and 1600 drawings of features useful for identification of the tree species. Also included are 136 range maps and color maps of Canada's for est regions and plant hardiness zones.
