bird species as well as possums, raccoons, and skunks. The surrounding area also hosts a wide variety of birds, including common species such as blue jays and cardinals; wild turkeys; and birds of prey including red-tailed hawks and owls. Animals within the area include Eastern and meadow voles, red-bellied salamanders, southern flying squirrels, opossums, white-footed deer mice, and cottontail rabbits, as well as eastern grey squirrels and raccoons. Management The Fort Tryon Park Trust is a nonprofit organization that helps maintain and improve Fort Tryon Park. It was founded in 1998 as the Heather Garden Committee Endowment. Their mission statement is to "promote the restoration, preservation, and enhancement of this historic and scenic landmark for the benefit and use of the surrounding community and all New Yorkers and visitors." The trust secured numerous grants to maintain various parts of the park. Transportation The New York City Subway's IND Eighth Avenue Line () runs directly underneath Fort Tryon Park. It contains two stations serving the park: the Dyckman Street station at Broadway, Riverside Drive, and Dyckman Street on the far northeast corner of the park, and the 190th Street station at Corbin Circle in the park's far southeast end. , the 190th Street station entrance at Corbin Circle is closed for elevator repairs until September 2021. Several bus routes serve Fort Tryon Park. The northern terminals of the buses are at Corbin Circle, though the M4 bus is extended into the park to serve the Cloisters when the museum is open. Additionally, the buses serve Broadway on the park's eastern border. Use and significance Historic significance There have been numerous archeological findings in Fort Tryon Park since 1918. That year, Alanson Skinner, an archeologist with the National Museum of the American Indian, discovered "traces of Indian shell heaps, fireplaces, and pits, indicating an ancient camping ground". The historian Reginald Pelham Bolton wrote in 1924 that the intersection of 194th Street and Broadway may have been used as a seasonal camp, as evidenced by the presence of debris from the pre-colonial era underneath the overhangs in Fort Tryon Park between 194th and 198th Streets. It is unclear whether the subway excavations of the 1930s disturbed any shells or other materials, but despite the construction during that era, many materials are still buried in the ground. In the 1970s, Michael Cohn of the Brooklyn Children's Museum found oyster and clam shells as well
