This data package contains derived estimates and analysis data tables for monitoring data collected on salmonids (primarily Coho salmon, Oncorhynchus kisutch)at Golden Gate National Recreation Area (GOGA) and Point Reyes National Seashore (PORE) by the San Francisco Bay Area Network (SFAN). The monitoring objectives of this protocol are the following: 1. Determine long-term trends in distribution and abundance, size (length) of spawning coho salmon by counting numbers of spawners, carcasses, and redds along reaches at Olema, Pine Gulch, Redwood, and Cheda Creeks. 2. Determine long-term trends in abundance and condition of smolt coho salmon by conducting spring smolt trapping near mouths of Olema, Pine Gulch, and Redwood Creeks. 3. Determine long-term trends in distribution and abundance and condition of juvenile coho salmon by conducting summer basin wide surveys (general systematic surveys [GSS]) at Olema, Pine Gulch, and Redwood Creeks. 4. Determine long term trends in summer density, size, and age composition of coho salmon at preexisting index reaches at Olema, Pine Gulch, and Redwood Creeks. 5. Identify gross changes in habitat (pool:riffle) in Olema, Pine Gulch, and Redwood Creeks during basin wide GSS surveys. The data package includes the following tables: (1) Unidentified Salmonid Redds, (2) Juvenile Coho Survival Estimates, (3) Coho Smolt Numbers By Stream, (4) Coho Smolt Pre-Trap Catch Numbers, (5) Coho Smolt Population Estimates, (6) Coho Juvenile Multi Year Population Estimates, and (7) Coho Juvenile Single Year Population Estimates.
