This book traces the history of threats to species and habitat in California, from the time of the Gold Rush to the present. The author shows how, over the course of more than a century, scientists and conservationists came to view the fates of endangered species as dependent on the ecological conditions and human activities in the places where those species lived. The story begins with the tale of the state's extinct mascot, the California grizzly, and the conservation movements and laws that followed its disappearance. The second half of the book focuses on four high-profile endangered species: the California condor, the desert tortoise, the San Joaquin kit fox, and the Delta smelt. The author offers an account of how Americans developed a civil system in which imperiled species serve as proxies for broader conflicts about the politics of place. The book concludes that the challenge for conservationists in the twenty-first century will be to expand habitat conservation beyond protected wildlands to build more diverse and sustainable landscapes.
Estuaries are eternally enriched. Their positions at the foot of watersheds and their convenience as receiving bodies for the wastes of cites, towns and farms results in continuous addition of nutrients - those elements and compounds which are essential for organic production. Such materials must be added to these complex bodies of water to sustain production, since there is a net loss of water and its contents to the oceans. Enrichment from land and the ocean and the subsequent cycling of the original chemicals or their derivatives contribute to the extraordinarily high values of estuaries for human purposes. Many estuaries are able to assimilate large quantities of nutrients despite the gr...
