1 Draft Central Valley Salmon and Steelhead Recovery Plan for Sacramento River winter-run Chinook salmon Central Valley spring-run Chinook Salmon Central Valley Steelhead National Marine Fisheries Service Southwest Region November

2 Themes of the CV Recovery Plan This is a long-term plan that will take several decades to fully implement The recovery plan is intended to be a living document that is periodically updated to include the best available information regarding the status or needs of the species Implementation will be challenging and will require the help of many stakeholders The plan is intended to have realistic and attainable recovery criteria (i.e, de-listing criteria) 2

3 What are Recovery Plans? Purpose of the Endangered Species Act: To conserve (recover) listed species and their ecosystems Required under section 4(f) of the ESA for all Federally listed species Provide the road map to species recovery Must contain objective, measurable criteria for delisting a species Guidance documents, not regulations 3

4 Winter-run Chinook salmon (Endangered) 4

5 Status of Species Winter-run Chinook 5

6 Central Valley Spring-run Chinook salmon (Threatened) 6

7 Status of Species Spring-run Chinook Declining abundance across range: Extinction risk is increasing Central Valley Spring-run Chinook Salmon Adult Summer Holding Escapement 25,000 20,000 15,000 10,000 5,000 Rivers/Creeks Sacramento Battle Clear Beegum Antelope Mill Deer Big Chico Butte

8 Central Valley steelhead (Threatened) 8

9 Key Threats Dams: Block passage; 95% loss of spawning habitat for Central Valley salmonids Water Diversions: Juvenile entrainment and flow modifications In-river Predation: Contributes to low juvenile survival rates Climate: Recent coastal upwelling conditions, long-term precipitation patterns Habitat Loss and Fragmentation: loss of floodplain and riparian habitat Hatcheries: Hybridization and reduced fitness Fishery Effects: Ocean harvest of winter-run and spring-run Chinook salmon Water Quality: Impaired water quality in the lower river systems and the Delta 9

10 Recovery Planning Foundational Principles: Apply concepts of VSP Viable Salmonid Populations (VSP) Technical Recovery Team: Population structure, extinction risk, species viability Recovery must address the entire natural ecosystem (freshwater spawning, rearing and migration areas; estuarine habitats, and the Pacific Ocean) Viable populations require a network of complex and interconnected habitats, which are created, altered, and maintained by natural physical process Recovery strategies must address key threats 10

12 Proposed Recovery Strategy A two-pronged approach Secure existing populations (and habitat) Core 1 Populations: Independent populations Core 2 Populations: Dependent populations Core 3 Populations: Small, ephemeral populations Reintroduce fish to historic habitats Primary candidate reintroduction areas Secondary candidate reintroduction areas Areas not considered for reintroduction 12
