The Estabrook Woods is a wild tract of more than of woodland, hills, ledge, and swamp two miles north of the Town of Concord. It is the largest contiguous and undeveloped woodland within thirty miles of Boston. However, the woods have a history of human disturbance dating back to the Algonquian Native Americans who used controlled burning to clear tracts of land. Later, colonists cleared much of Estabrook for agriculture and pastures, although vegetation has since rejuvenated. The Woods are named for the Estabrook family, prominent in the area since colonial times. The first Estabrook in the area, Capt. Joseph, purchased his farm, now part of Estabrook Woods, from the Pelham family, then of Rhode Island. Henry David Thoreau is intimately associated with this area, which he called Easterbrooks Country. In his Oct. 20, 1857 journal entry, one of several on the woodland, he writes: “What a wild and rich domain that Easterbrooks Country! Not a cultivated, hardly a cultivatable field in it, and yet it delights all natural persons.” The woods are also home to the unimproved Estabrook Road, which Minutemen used at the start of the American Revolutionary War. Today, stone markers mark the path taken by Minuteman traveling south toward Concord. During the early 20th century, a small number of Concord families began to acquire the land in Estabrook Woods. In 1932, they successfully petitioned the town to close and discontinue the old logging trail known as Old Estabrook Road, ensuring it would be protected from residential development. Around 1965, these families, along with Harvard and Middlesex School, began working together to create a nature preserve, establishing Harvard's Concord Field Station and placing major restrictions on development of many remaining private lands. In 1996, Concord and Carlisle worked together on the "Campaign for Estabrook Woods" which placed an additional 400 acres into conservation. Estabrook Woods has significant ecological significance to the area.
It provides habitats for five state-listed endangered species: A globally-endangered dragonfly and four Species of Special Concern: the Blue Spotted Salamander, the Elderberry Long horned Beetle, the Spotted Turtle, and the Mystic Valley Amphipod. The woods are also a breeding site of at least three watch list species: the Spotted Salamander, Northern Leopard Frog, and Northern Goshawk.
Estabrook Woods is home to over 159 different species of bird, six species of thrush, four species of owl and ten of hawk.
In October, 2001, The Massachusetts Office of Environmental Affairs designated the Estabrook Woods as 'core habitat' whose preservation is needed to protect biodiversity.
The Estabrook Woods are bordered by Lowell Road to the west, Monument Street to the east, and Bedford Road to the north. Though accessible to the public, most of Estabrook is privately owned by Harvard University, Middlesex School, and a number of smaller landowners.
