Spinner Island proudly supports waterfowl and habitat restoration and conservation. We support Ducks Unlimited and California Waterfowl Association and actively work to improve our property for resident and migrating birds.
Spinner Island provides the southeasternmost boundary of the Suisun Marsh. The Suisun Marsh is the largest contiguous brackish water marsh remaining on the west coast of North America.. It is a critical part of the San Francisco Bay-Delta estuary ecosystem. Encompassing 116,000 acres, the Suisun Marsh includes 52,000 acres of managed wetlands, 27,700 acres of upland grasses, 6,300 acres of tidal wetlands, and 30,000 acres of bays & sloughs. It is home to public waterfowl hunting areas and 158 private duck clubs.
The Marsh encompasses more than 10% of California's remaining natural wetlands and serves as the resting and feeding ground for thousands of waterfowl migrating on the Pacific Flyway. In addition, the Marsh provides essential habitat for more than 221 bird species, 45 animal species, 16 different reptilian and amphibian species, and more than 40 fish species. The Marsh supports 80% of the state's commercial salmon fishery by providing important tidal rearing areas for juvenile fish allowing them to grow twice as fast as those reared in the upper watershed, thus, greatly enhancing their survival.
Two hundred and thirty miles of levees within the Marsh provide critical protection of the drinking water for 22 million people by preventing salt water intrusion into the Delta. The Marsh's large open space and proximity to vast urban areas makes it ideally suited for wildlife viewing, hunting, boating, and other recreation opportunities.
