Del Real C, Carlisle S, Reichmuth ML, Ketcham BJ. 2007. Adult Escapement Monitoring Program Summary. 2006-2007. Natural Resource Technical Report NPS/SFAN/NRTR— 2007/001
Annually, spawner surveys are conducted in watersheds within and adjacent to SFAN Park units, including Point Reyes National Seashore (PORE), Golden Gate National Recreation Area (GOGA), and Muir Woods National Monument (MUWO). These surveys concentrate primarily on federally endangered coho salmon (Oncorhynchus kisutch) and federally threatened steelhead (O. mykiss). The watersheds within Coastal Marin County and summarized in this report, including Olema Creek, Redwood Creek, and Pine Gulch Creek (Figure 1) are considered to support the most southerly stable populations of coho salmon. The report summarizes the 2006-07 spawning results for the monitored watersheds. Surveys are typically conducted weekly between December and February, but are highly dependent upon the precipitation accumulations during the season. Redds, live fish, and carcasses are counted in an attempt to better understand trends in abundance and distribution.
