The San Francisco Bay Shorebird Survey is a coordinated, multi-partner monitoring program to assess annual shorebird population changes. Many North American shorebird species are thought to be in decline and the influence that changing wetland habitats (specifically in the San Francisco Bay) have on these populations is not well understood. SFBBO biologists and citizen scientists survey more than 40 sites across the South San Francisco Bay and provide data to the broader Bay region. Data from this survey provides guidance to managers on what shorebird species are at greatest risk and what habitats they most rely upon. This survey also contributes to larger shorebird monitoring efforts in the Pacific Flyway Shorebird Survey and Migratory Shorebird Project.
