As we emphasized in the Preface, this book was written under very unusual circumstances. We began the book shortly after the lynx was proposed for listing as threatened or endangered under the Endangered Species Act (ESA). Our purpose was to elucidate the scientific basis for conserving lynx for use in listing deliberations and in establishing land management policy, including a strategy for lynx conservation. The listing decision was delayed by six months so that our findings could be considered. Authors, editors, and production staff worked overtime and weekends to produce camera-ready copies of each chapter, and these were posted on the Internet for public comment during a specified time period. Draft copies of the chapters were provided to the U.S. Fish and Wildlife Service and land management agencies prior to publication so they could begin to consider our findings in their ongoing assessments and planning processes. We have, therefore, been in the unusual position of seeing some of the sociopolitical implications of our findings even as we wrote them.
