With more than 2,800 original watercolor illustrations, John Muir Laws has masterfully catalogued over 1,700 species of Sierra trees, wildflowers, ferns, fungi, lichens, fish, reptiles, amphibians, birds, mammals, insects, and other small animals. The guide is designed for quick and easy use in the field. Color tabs and a unique system of keys and organization assist in the quick identification of the living things encountered along the trail, while Laws s illustrations capture the feeling of plants and animals with detail critical for their classification.
