Presenting all the native and naturalized trees of the western United States and Canada as far east as the Great Plains, this book includes: range maps that provide a thumbnail view of distribution for each native species; "Quick ID" summaries; scientific and common names; information on the most recently naturalized species; and a key to leaves.

"This is an outstanding guide. I was constantly amazed at the amount of information that the authors have gathered and presented in a clear, readable style."--Arnold Tiehm, University of Nevada, Reno

"This exceptional guide will be a useful reference for arborists, foresters, landscape architects, and gardeners. The botanical descriptions are excellent, the text is easy to read, and the side notes provide interesting facts that help to fully describe the species. The illustrations are very effective, providing sufficient detail for identification. And the location maps for species nativity are a welcome bonus."--Dennis Swartzell, board-certified master arborist, Henderson, Nevada

"A splendid book, comprehensive in a way that readily answers the questions I bring home from the field."---Paul J. Willis, Books and Culture
