Brian Gray and a group of co-authors have published a book called, Managing California's Water: From Conflict to Reconciliation (Public Policy Institute of California, 2011). The book's authors propose moving away from the current strategy: taking desperate action to save one species at a time under the federal and state Endangered Species Acts. Instead, they argue that a broader approach is more promising: creating better conditions for many species and addressing the multiple causes of ecosystem decline.
The book is available in bookstores, on Amazon in hard copy or Kindle, and on Google Books. There also is a link in the text below to the book and executive summary on PPIC's web site.
