During the development boom following WWII, Margaret Pearmain Welch feared for the landscape in the northwest corner of Framingham. To help conserve it, she donated 87 acres of land over several years, starting in 1959, and provided the core of SVT’s first reservation beyond our original Wayland-​Sudbury base.

Berlin Meadows, owned by the Town of Berlin, is a mix of open field, wet meadow, forested wetland and upland, and dense successional scrub. It provides natural flood control and storm drainage to neighboring communities. The Town donated a conservation restriction on Berlin Meadows to SVT.

Brues Woods' upland trails pass through mature pines. Plank walkways carry the trail across Bridge Brook and through damp areas in the adjacent wooded wetland with its tangled under-story and fallen trees.

A local Eagle Scout created an interpretive nature trail brochure that describes the trees at six markers along the trail. A complete tour takes less than an hour over moderately easy terrain, with some briefly steep spots.

SVT’s Cowassock Woods is nestled in the much larger Ashland Town Forest. Together, these lovely properties span more than 500 acres and are rich in both human and natural history.

As you walk the entrance trail at Cowassock Woods, you can still see signs of a development that was planned for the site; SVT acquired the 50-plus acres of Cowassock Woods in two stages in 1984 and 1992, after the plans fell through.

Cowassock Woods and Ashland Town Forest are composed of a mosaic of mixed hardwood forest types, wetlands, vernal pools and stream corridors.

Consider how remote and novel that [Gowing’s Swamp]. Beneath it is a quaking bed of sphagnum, and in it grow . . . plants which scarcely a citizen of Concord ever sees. It would be as novel to them to stand there as in a conservatory, or in Greenland . . . .—Henry David Thoreau, August 30, 1856

In 2009, the Town donated a conservation restriction (CR) on the property to SVT; this CR ensures the property will never be developed into housing lots. SVT works with the Town of Bedford to ensure that the conservation values on the land are maintained.
