The Center for California Water Resources Policy and Management works to invest in and synthesize solutions to water supply challenges through creative Delta-related research, cutting edge monitoring and modeling, and unique examination of the multiple environmental stressors that are effecting the ecosystem. We support research that is specifically designed to inform future management decisions in the Delta by linking the newest and best scientific information to management decision making.

The Center’s ultimate goal is to inform the development of water management recommendations that promote the most effective uses of California’s water to support both healthy ecosystems and a vibrant economy, based on sound science.

A Critical Assessment of the Use of Surrogate Species in Conservation Planning in the Sacramento-San Joaquin Delta, California (U.S.A.)


Conservation biology has provided wildlife managers numerous conservation planning tools, including surrogate species concept. The authors examined the use of surrogate species in the Sacramento-San Joaquin Delta, California. Federal and state agencies have applied the surrogate species concept in the region, under the federal and state endangered species acts. During the same period, conservation biologists demonstrated that the surrogate concept is generally unsupported by ecological theory and empirical evidence.

The Route to Best Science in Implementation of the Endangered Species Act Consultation Mandate: The Benefits of Structured Effects Analysis

Dennis D. Murphy and Paul S. Weiland

The Endangered Species Act is intended to conserve at-risk species and the ecosystems upon which they depend, and it is premised on the notion that if the wildlife agencies that are charged with implementing the statute use the best available scientific information, they can successfully carry out this intention.
