Variability in habitat value of commercial salt production ponds: implications for waterbird management and tidal marsh restoration planning

In San Francisco Bay, three former salt pond complexes (Alviso, Eden Landing, and Ravenswood) have been decommissioned, i.e., taken out of commission, and are planned for marsh restoration. We compared total and foraging abundance and densities of ducks, shorebirds, and piscivores, as well as eared grebes (Podiceps nigricollis) among decommissioned and commercial pond complexes.
