Sunkhaze Meadows NWR encompasses the second largest peat bog in Maine. Peat deposits, up to 18 feet thick in places, were at one time threatened by development. Recreational opportunities include hiking, fishing, boating, hunting, and educational programs at the visitor center.

The area hosts nearly 200 different bird species, more than 30 mammal species, and untold numbers of amphibians, reptiles, and invertebrates. The sedge wren, an endangered species in Maine, have been observed here.

Small impoundments have been created to restore wetlands lost during private ownership. Unity College utilizes the area as an outdoor classroom. Ten acres of hayfield are maintained for upland nesting birds which depend on grassland habitat.
