Some of California's most contentious battles over land and water often end up being decided by scientific findings. Understandably, researchers want to ensure that their studies be applied appropriately. To discuss the role of research in decision-making about habitat conservation and endangered species protection, participants in some of the state's most high-profile environmental controversies will gather at UC Davis on Oct. 29-30. The meeting will feature policy-makers Mike Spear, regional director of the U.S. Fish and Wildlife Service; Doug Wheeler, Secretary for Resources for the state of California; and Betsy Rieke, director of the Natural Resources Law Center at the University of Colorado and the mediator for the historic 1994 Bay Delta accord. Sessions cover several issues, including science and policy in the recent Bay-Delta accord, which is closely related to the upcoming state ballot measure Proposition 204.
