Massachusetts Divisions and Units

Third Island Unit

Third Island is a 4-acre island in the Connecticut River in Deerfield, Massachusetts. The island is located 4.3 miles upriver from the Sunderland Bridge at Route 116. The refuge was established when this island was donated to the Service from the Connecticut River Watershed Council in 1997. It is upriver from First Island and Second Island, which are owned and managed by the Massachusetts Division of Fisheries and Wildlife. The island is mostly hardwood forest, with some shallow water habitats. In recent years, bald eagles have nested here, and because of that, the island is closed to public entry from January 1 through July 31, until young eagles have fledged. Along with the other two islands, Third Island provides valuable shallow water habitats for spawning Atlantic sturgeon and both American shad and blueback herring. Mussels are common on the river bottom near Third Island. The Unit is open to the public for wildlife observation and photography, environmental education and interpretation, and hunting and fishing, according to State regulations.  The Unit is open to the public from sun-up to sun-down, except when it is closed to all access from January 1 to July 31.

Honey Pot Unit

The Honey Pot Unit, a 21-acre parcel acquired in 1999, is located off Honey Pot Road in Westfield, Massachusetts. It is comprised of a complex of vernal pools and scrub/shrub wetlands that support three rare vertebrate and two rare invertebrate species. This unit is adjacent to the state’s Honey Pot Natural Heritage Area. The Unit is open to the public from sun-up to sun-down, year round. It is open to the public for wildlife observation and photography, environmental education and interpretation, and hunting and fishing, according to State regulations.

Wissatinnewag Unit

The 21-acre Wissatinnewag Unit was acquired by the Service in 2001. The site lies opposite the Great Falls Discovery Center on the upper slope above the Connecticut River in Greenfield, Massachusetts. The predominant habitat is hardwood forest on a steep, southeast facing slope. The forest serves as important migratory bird stopover habitat during the spring, and supports a variety of nesting songbirds. The Wissatinnewag Unit is closed to the public for resource protection.

Mt. Tom Unit

The Mt. Tom Unit is a 141-acre parcel of land which is part of a 1,800-acre area adjacent to the Connecticut River near Easthampton, Massachusetts. Mt. Tom is part of the Metacomet Range, formed over 200 million years ago due to volcanic activity and subsequent geologic and erosive pressures. This unit is a relatively steep, east-facing slope comprised of Northern hardwood forest and meadows with traprock exposed on the upper slopes. There are a number of vernal pools, intermittent drainages, and a small reservoir originally constructed for snowmaking. There are no developed trails on the unit, however, the Metacomet-Monadnock Trail runs along the ridge at the top of the mountain. The Unit is open to the public from sun-up to sun-down, year round. The Unit is open to the public for wildlife observation and photography, environmental education and interpretation, and hunting and fishing, according to State regulations.

Fannie Stebbins Unit

Beginning more than fifty years ago, members of the Allen Bird Club worked to acquire approximately 362 acres of land between Interstate 91 and the Connecticut River in Longmeadow, Massachusetts. This property became the Fannie Stebbins Memorial Wildlife Refuge. The Stebbins property and the larger floodplain area known as the "Longmeadow Flats" had been designated as a National Landmark by the U.S. Department of the Interior and an Important Bird Area by the Massachusetts Audubon Society.

The area is subject to periodic flooding that is representative of this habitat. It includes bordering swamps, ponded water, vegetated wetlands, meadows, hardwood forest and riverbank. It encompasses one of the largest remaining patches of floodplain forests and wetlands along this heavily human-impacted section of the Connecticut River. The wetlands provide breeding habitat for marsh birds and stop-over habitat for migratory waterfowl. 

The Unit is open to the public from sun-up to sun-down, year round. The Unit is open to the public for wildlife observation and photography, environmental education and interpretation, and fishing, according to State regulations. The Fannie Stebbins Unit is not open for hunting.
