Conscience Point is part of a unique wetland network: the Sebonac Creek/West Neck/Scallop Pond System or, in local vernacular, the Cow Neck Complex. That system encompasses about 300 acres of open water, salt marsh, irregularly exposed tidal flats, and aquatic beds. The Cow Neck Complex includes large, privately owned wetlands and wetlands owned by The Nature Conservancy.
The extensive salt and brackish tidal marshes include a number of tidal creeks, ponds and coves. The marshes characteristically comprise low and high marsh areas dominated by smooth cordgrass and saltmeadow cordgrass, respectively, with various admixtures of glasswort, spikegrass, black grass, and sea lavender, among others. Their upland shrubby edges often are dominated by groundselbush, marsh elder and bayberry, grading into upland forest of red maple and white oak.
