The William T. Davis Wildlife Refuge (WTDWR) is an wildlife refuge straddling the New Springville and Travis sections of Staten Island. The park was named in honor of Staten Island native William T. Davis, a renowned naturalist and entomologist who along with the Audubon Society started the refuge with an original acquisition of . Additional acreage was acquired in increments and the park is today . Beginning in 2010, the adjacent 223 acre North Park section of Freshkills Park (what the Freshkills landfill will become) has undergone preparation to serve as an expansion of the wildlife refuge. This refuge is the sixth largest park in New York City out of a total of 1,700 parks; it is only smaller than Central Park. The United for Wildlife Rehabilitation and Education Center is located at the William T. Davis Wildlife Refuge near the intersection of Travis and Richmond Avenues. The center seeks “to care for sick, injured and orphaned wildlife and return them to the wild.” The center is sponsored by the New York City Parks Department and serves as a holding facility for the New York State Department of Environmental Conservation. Injured animals convalesce at the facility and are eventually returned to the wild. The refuge is at the confluence of Main and Springville Creeks, two tributaries of Freshkill Creek, a tidal creek which is connected to the Arthur Kill. Within the refuge there are expansive salt marshes with low marsh bordering the creeks and flooding twice daily with the high tide and a more expansive area of high marsh which floods occasionally during exceptionally high tide. In the low marsh, saltmarsh cordgrass (''Spartina alterniflora'') is the dominant species while saltmeadow cordgrass (''Spartina patens'') is found in the high marsh. There are degraded areas of the marsh in which the common reed (''Phragmites australis''), an invasive species, has supplanted the native cordgrass; this generally occurs in the high marsh zone where the soil is saturated but infrequently inundated. In addition to the salt marshes there are forested uplands and a swamp forest and small spring-fed ponds. *Marine life: The marine life present in the refuge includes the fiddler crab (''Uca pugnax''), ribbed mussel (''Geukensia demissa''), clam and oyster. *Bird species: Over 117 bird species have been recorded at the William T. Davis Wildlife Refuge, including sharp-tailed sparrow (''Ammodramus caudacutus''), and wood duck (''Aix sponsa''). Among the species of raptors which frequent the park are red-tailed hawks (''Buteo jamaicensis'') red-shouldered (Buteo lineatus), and rough-legged (Buteo lagopus) hawks and osprey. There are also various species of owl such as Barn (''Tyto alba''), great horned (''Bubo virginianus''), and short-eared (''Asio flammeus''). The Great blue heron hunts fish along the tidal marshes. *Mammals: Muskrats (Ondatra zibethica) live along the marshes; there are also raccoons, eastern grey squirrel, chipmunk, and a few species of field mouse. 〔(William T. Davis Wildlife Refuge- NYC Parks )〕 In addition to the invasive common reed, some sections of the refuge especially along Travis Ave. are overrun by Japanese knotweed. The fresh-water New Springville Creek, which originates in the Greenbelt, flows into the park. The creek is subterranean for most of its length, having been enclosed in pipe.〔Morris's memorial history of Staten Island, New York, Volume 1 By Ira K. Morris p. 364〕 ==Geology== The Palisades Sill extending from upstate New York along the Hudson River in New Jersey, is exposed until Jersey City, New Jersey. The formation then becomes entirely subterranean until it reaches the refuge where a small section breaks the surface in a swamp off Travis Ave. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「William T.
