The floodplain offers a natural sanctuary for not only people, but for wildlife, including turtles, beaver, migratory waterfowl and other birds, such as the cardinal, oriole, bald eagle, osprey, pileated woodpecker, and rose-breasted grosbeak.

This generous gift of land ensures the permanent protection of one of the state’s largest mostly undeveloped lakes (234 acres). This reservation surrounding Grafton Pond was the gift of an anonymous donor who wanted to preserve the wilderness pond and its seven miles of shoreline as one of the remaining sanctuaries for nesting loons. An advisory committee was formed that year to raise funds to create an endowment for the management of the property and to offer advice on land use and initial programs.

The Sagamore Creek area holds significant agricultural heritage. In fact, the site of Creek Farm, believed to have been occupied by early settler Nicholas Rowe in 1640, was one of the earliest places in New Hampshire to be cultivated by European settlers. It was later part of the 18th-century farm of the royal governor of New Hampshire, Benning Wentworth. Some of the fieldstone boundary walls that cross the property define ancient property lines that were recorded on early maps of the area.
