September, 2022 Sawyer Brook Headwaters Update
in 2019, Eastman Charitable Foundation awarded a grant of $7,500 in support of the purchase and permanent protection of the unique 386-acre Sawyer Brook Headwaters property in Grantham. As designated by NH Fish and Game, the property includes highly ranked wetlands and a wildlife habitat, as well as a critical section of an existing wildlife corridor between nearby conserved parcels. The property has public access, allowing visitors of all ages to enjoy hiking, hunting, mountain biking, running, snowshoeing, skiing, snowmobiling, nature observation and other low-impact activities.
In August of 2022, new signage was been placed at the parking area and access point on Walker Road acknowledging the support of Eastman Charitable Foundation, the State of New Hampshire, and other organizations.
