Background
The Central Valley Technical Recovery Team has published five reports that provide scientific guidance for planning the recovery of listed Chinook salmon and steelhead in the Central Valley. Population structure of threatened and endangered chinook salmon ESUs in California's Central Valley basin and Historical population structure of Central Valley steelhead and its alteration by dams
identify the "building blocks" that might be used to recreate viable ESUs, and contrast historical and contemporary structure of the ESUs. Framework for Assessing Viability of Threatened and Endangered Chinook Salmon and Steelhead in The Sacramento-San Joaquin Basin provides criteria that can be used to develop population and ESU-level viability goals, which may be used in the development of formal delisting criteria in recovery plans. In Monitoring and research needed to manage the recovery of threatened and endangered Chinook and steelhead in the Sacramento-San Joaquin basin, TRT members evaluated whether existing monitoring programs will provide the data needed to conduct viability assessments, and identified a number of high-priority research areas that could advance recovery efforts in the future. Finally, Rob Schick and Steve Lindley published a paper in the Journal of Applied Ecology applying concepts and tools from graph theory to develop quantitative descriptions of ESU structure; the example application was Central Valley spring-run Chinook salmon. These tools can be used to compare quantitatively the structure of current or possible future ESU configurations to the historical configuration, which was presumably viable.
