Book Description
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.

Book Description
Most research into humans' impact on the environment has focused on large-scale societies; a corollary assumption has been that small scale economies are sustainable and in harmony with nature. The contributors to this volume challenge this notion, revealing how such communities shaped their environment—and not always in a positive way. Offering case studies from around the world—from Brazil to Japan, Denmark to the Rocky Mountains—the chapters empirically demonstrate the substantial transformations of the surrounding landscape made by hunter-gatherer and limited horticultural societies. Summarizing previous research as well as presenting new data, this book shows that the environmental impact and legacy of societies are not always proportional their size. Understanding that our species leaves a footprint wherever it has been leads to both a better understanding of our prehistoric past and to deeper implications for our future relationship to the world around us.

Book Description
There has been a deluge of material on biodiversity, starting from a trickle back in the mid-1980's. However, this book is entirely unique in its treatment of the topic. It is unique in its meticulously crafted, scientifically informed, philosophical examination of the norms and values that are at the heart of discussions about biodiversity. And it is unique in its point of view, which is the first to comprehensively challenge prevailing views about biodiversity and its value. According to those dominant views, biodiversity is an extremely good thing – so good that it has become the emblem of natural value. The book's broader purpose is to use biodiversity as a lens through which to view the nature of natural value. It first examines, on their own terms, the arguments for why biodiversity is supposed to be a good thing. This discussion cuts a very broad and detailed swath through the scientific, economic, and environmental literature. It finds all these arguments to be seriously wanting. Worse, these arguments appear to have consequences that should dismay and perplex most environmentalists. The book then turns to a deeper analysis of these failures and suggests that they result from posing value questions from within a framework that is inappropriate for nature's value. It concludes with a novel suggestion for framing natural value. This new proposal avoids the pitfalls of the ones that prevail in the promotion of biodiversity. And it exposes the goals of conservation biology, restoration biology, and the world's largest conservation organizations as badly ill-conceived.
