Trees in Canada celebrated its 100th anniversary (1917 to 2017) with a redesigned reprint that has a modern look. It features a striking new cover and an easier-to-read, engaging content with a new font and standardized photographs many of which bleed.

Two new species were added to the book, bear oak (Quercus ilicifolia (Wangenh)) and swamp cottonwood (Populus heterophylla L.), and minor taxonomic changes were made.

The standardized photographs, a highlight of the redesigned Trees in Canada, make it easier for users of the book to identify trees, and contribute to a splendid redesign of this widely consulted and cited reference.

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 non-technical language and in an easy-to-use format. Trees in Canada includes descriptions of introduced species that are commonly planted or naturalized.

The text 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 essential features, 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 forest regions and plant hardiness zones.

Trees In Canada is the most comprehensive book on the trees of Canada and the northern United States ever published and is an essential tool for the amateur naturalist and forest science professional, landscape architect, student, or teacher, and a collectible for all those fascinated by trees and forests.
