Harbor Seal Monitoring, San Francisco Bay Area, Annual Report
Manna J, Roberts D, Press D, Allen S. 2006. Harbor Seal Monitoring, San Francisco Bay Area, Annual Report. National Park Service
Annual monitoring report (2006) of harbor seals (Phoca vitulina richardii) the only year round pinniped in the San Francisco Bay Area. The monitoring project area focuses on Point Reyes populations which, other than Channel Islands, represents the largest concentration of the State of California's mainland breeding population. Selected colonies have been monitored at Point Reyes since 1976. The objectives of the long-term monitoring are to detect changes in population numbers, detect changes in reproductive success, and identify anthropogenic or environmental factors that might affect population status and trends. The information in the annual report is a summary of the data collected in Point Reyes National Seashore and Golden Gate National recreation Area during the 2006 breeding and molting seasons, March-July. Summary data collected as part of a region-wide survey effort includes adjacent areas, (San Francisco Bay, San Mateo County and Sonoma County) where NPS surveys were conducted in conjunction with other agencies and organizations.
