California’s wetlands have significant economic and environmental value, providing benefits such as water-quality maintenance, flood and erosion attenuation, prevention of saltwater intrusion, and wildlife habitat.
Wetlands constitute less than three percent of the State, but they have had a major economic effect on Hawaiian society both before and after European contact. Wetlands are habitats for several species of birds and plants endemic to the Hawaiian Islands.
