Islands have always been fascinating places, their separateness evoking a sense of mystery and inspiring a yearning for exploration. California's islands are unique evolutionary laboratories, places where plants and animals have grown and interacted in isolation for millions of years. This comprehensive book discusses both the human and the natural history of the islands of California, including all eight Channel Islands, Ano Nuevo, the Farallons, and the islands of San Francisco Bay. It is also useful as a field guide for visitors, and details on reaching the islands are contained in the first chapter. The authors explore the formation of the islands; discuss the history of human habitation, beginning with the Native Americans who first visited the islands 12,000 years ago; and provide a thorough introduction to the marine and terrestrial biotas of the islands. The authors also discuss past damage and ongoing threats to island ecosystems, including devastation caused by the introduction of non-native animals and plants.Large herbivorous animals in particular have caused considerable damage, since island plants evolved in the absence of herbivores and therefore have no defenses against them. At present all of California's islands are managed by conservancies and public agencies such as the National Park Service and State Park system, and various environmental organizations are working with them to return the islands to their original condition.

In this comprehensive and abundantly illustrated book, Allan A. Schoenherr describes the natural history of California-a state with a greater range of landforms, a greater variety of habitats, and more kinds of plants and animals than any area of equivalent size in all of North America. A Natural History of California focuses on each distinctive region, addressing its climate, rocks, soil, plants, and animals. The second edition of this classic work features updated species names and taxa, new details about parks reclassified by federal and state agencies, new stories about modern human and animal interaction, and a new epilogue on the impacts of climate change.

This thoroughly revised, entirely rewritten edition of what is the essential reference on California’s diverse and ever-changing vegetation now brings readers the most authoritative, state-of-the-art view of California’s plant ecosystems available. Integrating decades of research, leading community ecologists and field botanists describe and classify California’s vegetation types, identify environmental factors that determine the distribution of vegetation types, analyze the role of disturbance regimes in vegetation dynamics, chronicle change due to human activities, identify conservation issues, describe restoration strategies, and prioritize directions for new research. Several new chapters address statewide issues such as the historic appearance and impact of introduced and invasive plants, the soils of California, and more.
