Notes:

Estimate (derived from redd counts for entire watershed except Butano Creek) provided by California Department of Fish and Wildlife. The California Coastal Salmonid Monitoring Program for Pescadero River initiated in 2010/11. Zeros represent no spawners detected. The 95th % confidence interval is 224 to 274 for steelhead. Monitoring ended prior to end of steelhead migration. Thus, accurate estimates could not be determined. Sample size too small to make population estimates at watershed scale. Sample size was set for the regional scale. Data are preliminary and subject to change.

Coho salmon are federally listed as endangered. 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 2012, NMFS 2016).

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.
