The Decker Island Wildlife Area is a 34-acre property. Wildlife consists of a variety of terrestrial mammals, aquatic furbearers and bird populations. Birds comprise the major portion of wildlife, attributable to the habitats on and surrounding the island: open water, mudflats and riparian and emergent vegetation. These niches provide some environments for waterfowl, egrets, herons, gulls, terns and songbirds. The land surrounding Decker Island is used mainly for agriculture.
