Long-term Monitoring of Coho Salmon and Steelhead Trout During Freshwater Life Stages in CoastalMarin County, 2011 Annual Report.

摘要

The San Francisco Bay Area Network (SFAN) monitors populations of coho salmon (Oncorhynchus kisutch) and steelhead trout (O. mykiss) in watersheds at Point Reyes National Seashore, Golden Gate National Recreation Area, and Muir Woods National Monument. The watersheds, including Olema Creek, Redwood Creek, and Pine Gulch Creek, represent the majority of streams supporting salmonids in Marin County, California, and support a population of coho salmon near the southern extent of their range on the Pacific Coast. The National Park Service SFAN Inventory and Monitoring Program and California Department of Fish and Wildlife have supported monitoring of multiple coho salmon life stages in coastal Marin County watersheds since 1998. Monitoring includes: Adult escapement surveys; Outmigrant smolt trapping; and Basinwide juvenile coho surveys and summer index reach monitoring.
