What is Green River WMA like?
MassWildlife describes it: "This WMA consists of 5 separate parcels along Green River Road. They provide access for both hunting and fishing opportunities. The primary habitat types are upland forest consisting of mature transition hardwoods (oak, maple, beech) and white pine. There are about 30 acres of early successional habitat of primarily old fields and shrublands which can be found on the west side of the parcel abutting West Leyden Road."
On its habitat work: "Approximately 30 acres of old field habitat is managed on the parcel off of West Leyden Road. Clusters of apple trees were released to provide food for wildlife. Mowing is repeated once every 3-5 years to maintain old field habitat and surrounding shrublands."
On wildlife: "The Green River, named as such for its translucent emerald-like water, is a spectacular coldwater stream that is popular with swimmers in the summer. Green River WMA provides habitat for two rare dragonflies, including the ocellated darner, which flies low over the water in late summer and fall."
