Green Cay Wetlands (or Green Cay Wetlands and Nature Center) is a nature preserve located in Boynton Beach, Florida. The 100-acre (0.40 km2) property was purchased in 1999 from Ted and Trudy Winsberg, who used the property for farming. The Winsbergs sold the property for 1/3 of its appraised value with the condition that it would be made into a wetland.
