An edited volume recently released by Resources for the Future Press and Earthscan focuses on federalism and the U.S. Endangered Species Act (ESA).  The editors are Kaush Arha and Buzz Thompson, both of whom are associated with the Woods Institute at Stanford University.  According to these editors, the volume "explores the critical role that states can and should play in protecting the nation’s vast wealth of biodiversity."  The volume includes case studies of federalism and the ESA focused on individual species and chapters that address federalism and the ESA at the conceptual level.  I co-authored a chapter with Eileen Sobeck of the U.S. Department of the Interior regarding listing decisions, conservation agreements, and state-federal collaboration.  The volume is available for purchase from the publisher and online retailers.
