San Francisco Bay Fund Inventory of Projects

Waterbird use of commercial salt ponds at San Francisco Bay National Wildlife Refuge.

Organization: San Francisco Bay Bird Observatory
2005 & 2007 Grant Recipient - Alameda and Santa Clara Counties

Purpose

The South Bay Salt Pond Restoration Project, of which the Don Edwards San Francisco Bay National Wildlife Refuge (Refuge) is a part, is implementing a large-scale plan to convert 50% - 90% of the salt ponds within the Restoration Project area into tidal marsh. While the restoration of former salt ponds to tidal marsh will increase habitat for many species, it also will reduce the overall pond habitats available for waterbirds.

To support the adaptive management approach of the Refuge and the Restoration Project to maintaining baseline levels of waterbirds in this site of hemispheric importance along the Pacific Flyway, the San Francisco Bay Bird Observatory surveyed 22 salt evaporation ponds for waterbirds and collected water quality from September 2005 to September 2008. These salt ponds are owned by the Refuge and managed for salt production by Cargill Salt.

    This Report summarizes the surveyors findings in examining species richness, total abundance within and between complexes, as well as examining how the abundance of foraging guilds differed within each complex.
