Marshfield’s Pratt Farm offers 34 acres of conservation land along both the South River and Zenas Brook. A half-mile of trails extend through woods and wetlands, with bridges and small sections of boardwalk. Pratt Farm connects to Marshfield’s Bridle Path and Rail Trail.

Hunting is not allowed at Pratt Farm, nor at any of Marshfield’s other conservation properties.

Features

Pratt Farm was originally owned by one of Marshfield’s early settlers, Timothy Williamson, who operated the town “ordinary.” In 1663 he gave the town the land for the Training Green and First Congregational Church in exchange for additional property on the northern banks of the South River. These lands (now Pratt Farm) remained in his family until the mid-1800s. Williamson’s descendants eventually sold the land to the Pratts, who kept it for another 120 years. The town purchased the land in 2012 with Community Preservation funds.

Pratt Farm is part of the South River Greenway, interconnected green spaces along the South River in downtown Marshfield, including Veterans Memorial Park, South River Park, Pratt Farm, the Keville Footbridge, Dandelion Park and the Rail Trail/Bridle Path.

This land is within the region of the Massachusett (or Massachuseuk) and Wampanoag Native American tribes. To learn more about local tribes, we encourage you to interact with their members. The Mattakeeset band of the Massachusett, the Massachusett tribe at Ponkapoag, the Mashpee Wampanoag, and the Herring Pond Wampanoag also share information on their websites.

Trail Description

The trails are well-marked and easy to follow. From the entrance on Willow Street, the 0.35-mile main trail heads into the woods, then traverses two small bridges on Zenas Brook. It continues along the edge of the marsh and into the woods, with another bridge that crosses some wetlands. At the eastern end of the property, a tall set of stairs leads up to Marshfield’s Bridle Path & Rail Trail.

An additional 0.15-mile trail arcs away from the marsh before re-joining the main trail.

Habitats and Wildlife

The forest at Pratt Farm is relatively young and very flat. It’s easy to imagine how not too long ago, it was farmland. The woods are primarily pine and oak, with some birch, maple, fern and sweet pepper bush, plus greenbrier and the occasional cedar and sassafras. Some sections of the trails feature bright green moss.

Zenas Brook flows into the South River. It is one of the few cold water streams in Marshfield, key habitat for eastern brook trout. The brook is thought to be named for Zenas Thomas, who was born in 1742, and who in 1765 owned the farm (the old Arthur Howland family farm) across the street from where Pratt Farm is today. For many years Zenas Brook was impounded, creating a small pond on Pratt Farm.

The South River originates deep in Duxbury. Its source is in the Round Pond area, and from there it winds unobtrusively through the woods for several miles. Although one can view it from Route 3, and also from both South River Bog and the Camp Wing Conservation Area, it remains a narrow and mostly un-navigable stream until just below Veterans Memorial Park in Marshfield. From there it flows through South River Park, behind the playground of South River School, and under the Willow Street and Francis Keville Bridges. Wider at that point, and navigable at most tides, its course continues through the marshes as it runs parallel to Route 139, all the way to Rexhame. From there the river turns northward. It flows for 3 miles between Humarock and the mainland to Fourth Cliff, where it joins the North River at its outlet to the sea.
