In one easy-to-carry volume, this comprehensive field guide includes plants and wildlife it would otherwise take ten field guides to cover - all the flora and fauna you're most likely to see in the forest communities of the Rocky Mountains and the Southwest. With 53 color plates and more than 80 color photos illustrating trees, birds, mammals, wildflowers, mushrooms, reptiles and amphibians, butterflies, beetles, and other insects, this is the one field guide to carry!
