One more interesting bit:

"The present Vermont breeding spruce grouse population, estimated to be about 100 birds, is limited to the 24-square-mile Nulhegan Basin between the Wenlock Wildlife Management Area in Ferdinand and the so-called Yellow Bogs area in Lewis. The Nulhegan Basin provides habitat for the spruce grouse with stands of pure black spruce or mixed spruce, balsam fir, and larch dominating the vegetative cover of these lowland boreal forests. Scattered alder swamps and small open bogs are also present."
