The aim of the South Bay Salt Pond Restoration Project is to restore 50–90 percent of former salt evaporation ponds to tidal marsh in San Francisco Bay. However, hundreds of thousands of waterbirds use these ponds over winter and during fall and spring migration.
The South Bay Salt Pond Restoration Project aims to restore 50–90 percent of former salt evaporation ponds into tidal marsh in South San Francisco Bay, California. However, large numbers of waterbirds use these ponds annually as nesting and foraging habitat.
To offset for the loss of managed pond habitat during restoration of wetlands to tidal marsh, the South Bay Salt Pond Restoration Project is enhancing some of the remaining ponds by constructing islands for roosting and nesting waterbirds.
With global loss of natural wetlands, managed wetlands increasingly support energy requirements for wintering shorebirds and waterfowl. Despite numerous studies of avian bioenergetics in freshwater systems, less is known of the energetic capacity of estuarine systems.
We present baseline population estimates for shorebirds, waterfowl, and other waterbirds derived from published and unpublished data and summaries.
