Learn more about coastal wetlands

The Maine coast contains approximately 19,500 acres of wetland, more than any other New England state, New York, or Canadian province in the Gulf of Maine. Marsh types vary along the coast due to different geology and tidal ranges, from extensive back-barrier marshes in southern Maine to river-fringing tidal marshes and pocket wetlands in central and eastern Maine.

Much of the information in this section is from the extremely comprehensive guide, Maine Citizen’s Guide to Evaluating, Restoring, and Managing Tidal Marshes. Other sources for information on Maine’s salt marshes include Maine Salt Marshes: Their Function, Values, and Restoration and Salt Marshes in the Gulf of Maine, Human Impacts, Habitat Restoration and Long-Term Change Analysis.
