Under a National Park Service (NPS)/Wildlife Conservation Society Cooperative Agreement, we inventoried amphibians and reptiles at the William Floyd Estate (WFE), in Mastic, New York from April to September 2002. Six standardized sampling methods were used; anuran calling surveys, egg mass counts, visual encounter surveys, coverboards, turtle trapping surveys, and minnow trapping surveys. We also recorded animals encountered outside of standardized surveys as incidental encounters, including some after 2002.
