Field guide to the most common plant species of the Southwest found from 4,500 feet to 11,500 feet, all of which can be found in National Park Service areas. These areas are in Southern Utah, Southern Colorado, Arizona, New Mexico, and a bit of western Texas and Oklahoma. The soils are diverse, as are the climates in which these plants can be found. Here are low mesas, lofty peaks, deep canyons, and shallow arroyos, making up some of the most spectacular scenery in the United States. Each plant includes a detailed drawing of the plant, relative height, foliage, flowers and fruit. The book is also illustrated with color photos of plants and trees in situ.
