Book excerpt: Annotation. "The Sierra Nevada of California and Nevada is the longest continuous mountain range in the United States. It contains over 50 percent of California's total flora, approximately 405 plant taxa endemic to the Sierra, and 218 taxa that are considered rare. Wild Plants of the Sierra Nevada offers a comprehensive inventory of the flora of the entire range, including descriptions of the plants; their traditional and contemporary uses as food, medicine, or for making tools and other products; and information about their habitat. In addition, the authors provide an introduction that describes the natural history and ecology of the Sierra Nevada in terms of plant communities and life zones, addressing the impact of such variables as climate, elevation, soil, and precipitation. They also outline the basic principles of ethnobotany, the role of plants in human nutrition and medicine, the classification of plants, and methods of collecting plant specimens and protecting rare species. The plant descriptions are accompanied by line drawings of each major species, and there are a number of "quick keys" to help readers differentiate between similar species." "Wild Plants of the Sierra Nevada is an essential reference guide for botanists, hikers, outdoors aficionados, and readers interested in the traditional uses of native plants. It is the first complete summary of the flora of one of the richest and most diverse botanical regions of North America."--Jacket.
