"This guide provides description and photographs of 149 rare or endangered plants found in 10 counties in Northern California. Each description is accompanied by a photo of the mature plant (where available), a photo of the plant in its native habitat, a line art illustration of the plant showing diagnostic features, and a map showing the quadrangles where the plant has been found."--NHBS Encironment Bookstore.

The diversity of the earth's climates superimposed upon a complex configuration of physical features has provided the conditions for the evolution of a remarkable array of living things which are linked together into complex ecosystems. The kinds of organisms comprising the ecosystems of the world, and the nature of their interactions, have constantly changed through time due to coevolutionary interactions along with the effects of a continually changing physical environ ment. In recent evolutionary time there has been a dramatic and ever-accelerating rate of change in the configuration of these ecosystems because of the increasing influence of human beings. These changes range from subtle modifications caused by anthropogenically induced alterations in atmospheric properties to the total destruction of ecosystems. Many of these modifications have provided the fuel, food, and fiber which have allowed the expansion of human populations. Unfortunately, there have been many unanticipated changes which accompanied these modifications which have had effects detrimental to human welfare in cluding substantial changes in water and air quality. For example, the use of high-sulfur coal to produce energy in parts of North America is altering the properties of freshwater lakes and forests because of acidification.

In this photograph-driven field guide to California’s spectacular wildflowers, Laird R. Blackwell expertly provides several ways to find them in bloom: by month, by place, and by flower. The month-by-month descriptions—found in no other statewide guide—suggest what to see and where to go throughout the state during the blooming season. The author also supplies more than 300 locations arranged in 10 geographical regions, highlighting 67 of his favorite places with detailed driving and walking directions and difficulty, blooming times, and lists of predominant wildflowers as well as a featured flower. The guide contains more than 650 color photographs by the author, including 600 species arranged by flower, with natural history notes and places and months to find the flower in bloom. Throughout, experienced wildflower guide Blackwell shares his love of the beautiful places and flowers he has visited throughout California.

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.

Northwestern California is mainly known for its majestic redwood forests and incomparable coastline, but there is much more in its rich biota and scenery. The forests are part of the most diverse temperate coniferous forest in the world. Rugged mountains, numerous lakes, wilderness areas, and wild rivers attract outdoor enthusiasts and geologists came here to refine the theory of plate tectonics. Distilling a vast amount of knowledge, this book is the starting point for anyone who wants to explore the biological and geographical richness of northwestern California. John O. Sawyer describes the famous forests and varied landscapes from a geographic perspective. He explains its long geological history and the changing roles of fire and land use. The result of a lifetime of work, his rich narrative illustrates how the region, in many ways the least modified portion of the state, is a place where plants and animals have been shielded from extinction. Sawyer documents the restoration of dunes and forests, the control of nonnative plant invasions, and innovative approaches to restoring rivers so they can support thriving fisheries.

Grasses: Systematics and Evolution is a selection of the very best papers from the Proceedings of the Third International Symposium on Grass Systematics and Evolution held in Sydney, Australia in 1998. The papers represent some of the leading work from around the world on grasses and include reviews and current research into the comparative biology and classification. All 41 papers have been peer-reviewed and edited.
