Maine is rich in wetland resources. About 5 million acres, or one-fourth of the State, is wetland. Maine has a wide variety of wetlands, ranging from immense inland peatlands to salt marshes and mud flats along the coast.
The U.S. Fish and Wildlife Service is the principal federal agency tasked with providing information to the public on the extent and status of the nation’s wetland and deepwater habitats, as well as changes to these habitats over time.
