William T. Davis Wildlife Refuge is an 814-acre wetland and woodland preserve on Staten Island where Main and Springville Creeks meet before joining Freshkill Creek. Named for naturalist and entomologist William T. Davis, who helped establish it from an initial 52-acre acquisition with the Audubon Society, it grew through added parcels into one of New York City’s largest parks. Its salt marshes, upland forests, swamp forest, and spring-fed ponds support more than 117 bird species and other marsh wildlife. The refuge also includes an exposed section of the Palisades Sill and is tied to the future expansion of nearby Freshkills Park.
