Staten Island is located in the Sacramento-San Joaquin River Delta. It is a 9,200-acre island that has formed between the north and south forks of the Mokelumne River. The property is owned by the Nature Conservancy and is part of the Cosumnes River preserve.
The island has been a wintering destination for Sandhill cranes on the Pacific-flyway for more than 40 years. During the fall and winter, Staten Island is home to hundreds of thousands of migratory waterfowl. In the spring and summer, the property is managed as a large scale farming operation. Corn, rice, potatoes, and other crops are grown.
