This new field guide includes all the native and naturalized trees of western North America, from the arctic treeline in Alaska and Canada to northern Mexico. Some 400 trees are illustrated in color, along with comparison charts, range maps, keys to plants in leafless condition, and text distinctions between similar species. Beautiful work.
