Abstract

Our goal organizing this work was to update the landmark 1991 volume, Battle Against Extinction, and provide scientists and the public with a contemporary view of the status of aquatic ecosystems in North American deserts and rationales and approaches for their conservation. While predecessor editors W. L. Minckley and J. E. Deacon painted a grim picture, they noted that knowledge for effective conservation existed, but the missing ingredient was societal willingness to act. Many chapters in this new volume report worsening situations in the intervening decades, while others report modest success and cautious optimism. Several chapters also report practical, on-the-ground examples of conservation strategies for endangered species and habitats. However, the task of Standing Between Life and Extinction remains difficult and the future is ominous. Growth of mega-cities and vast river engineering projects to provide municipal and agricultural water have desiccated streams and simplified or destroyed aquatic habitats. Where water remains, invasive fishes and other species, introduced with reckless abandon, threaten native faunas. The result was numerous extinctions and escalating extinction debts for surviving natives, the latter exacerbated by extended drought, climate change, and unabated human population growth that is unhindered by the yet-absent will to change. Sustainable coexistence of humans and functioning aquatic ecosystems in the desert requires new and innovative strategies that are collaboratively developed and adopted. A conservation ethic going forward must include behavior constraints as the centerpiece, which would dictate humanity’s need to live sustainably with water supplies, natural habitats, and native species.
