About the Acadian Plains and Hills

The Acadian Plains and Hills is a region covering roughly the eastern-southeastern half of Maine, a large, bordering section in New Brunswick, a tiny sliver in Quebec, and both shores of the Bay of Fundy, including a small portion of Nova Scotia along this bay.

This region is mostly forested, and interspersed with numerous glacial lakes. It is less rugged than the Northeastern Highlands to the west, but still rather rocky. It is colder and less populated than the Northeastern Coastal Zone to the southwest.

Forest cover here is mostly spruce-fir on lowlands and northern hardwoods (sugar maple, American beech, and birch) on hills.

This region is bordered to the southwest along the coast by the warmer, denser-populated Northeastern Coastal Zone. This border is abrupt and marked by a clear geologic transition from a rocky coastline to a flatter coastline with greater fine sediments and abundant coastal marshes. To the northeast, this region borders and partly surrounds the Maritime Lowlands. Inland to the west and north, this region is bordered by the more rugged Northeastern Highlands; a different portion of this same region also borders this region to the southeast in Nova Scotia.
