From the USGS: Due to human activity, over 90% of tidal wetland habitat in San Francisco Estuary has been lost. One impact of this loss is its effect on fish and other aquatic organisms. Estuaries are dynamic transitional ecosystems which provide important habitat for aquatic life. Conservation of these species requires knowledge of estuarine features which drive their abundance and distribution.
In an article published in the journal Marine and Coastal Fisheries, California Water Science Center fish biologist, Frederick Feyrer and others discuss how the habitat features of the San Francisco estuary impact populations of aquatic species. In the research leading to the article, USGS scientists studied how stationary and dynamic habitat features of the San Francisco estuary impact populations of aquatic species.
