What We Need  

Estimate of the number of spawning fish nests (called redds) provided by the California Department of Fish and Wildlife. Population estimates of the number of fish will be based on these redd estimates. The California Coastal Salmonid Monitoring Program for Redwood Creek initiated in 2008/09. The 95th % confidence interval is 121 redds to 467 redds for coho and 460 redds to 1,892 redds for fall chinook. Monitoring ended prior to end of steelhead migration; accurate estimates could not be determined. Data are preliminary and subject to change.

Coho, Chinook and steelhead are federally listed as threatened. The “What We Need” spawner population abundance targets shown above represent just one of several criteria that the National Marine Fisheries Service considers when determining whether a species should be removed from the Federal List of Endangered and Threatened Wildlife and Plants (50 CFR 223.102). Recovering any of the species entails meeting criteria for abundance, productivity, diversity, and spatial structure across multiple watersheds, as well as criteria for alleviating threats (NMFS 2014, NMFS 2016). Steelhead adult spawning target is sum of 3,200 spawners for Lower Redwood Creek population and 2,600 spawners for Upper Redwood Creek population.

The 2014/15 snapshot is defined as fall 2014 to spring 2015, as per when salmon and steelhead return from the ocean to spawn. Fall Chinook spawning season is fall 2014. Coho season is fall through early January 2015. Steelhead season can start in fall 2014 but is primarily winter and spring 2015. Spring Chinook return in spring 2015 and spawn in fall 2015.
