A remarkable forest in the heart of western Massachusetts.



Why You Should Visit

The preserve protects a variety of habitats in a relatively intact forested landscape including forest, ponds, portions of Coles Brook and shrub wetlands. It abuts additional protected areas including the 3,400 acre Middlefield State Forest.

Why TNC Selected This Site

The Coles Brook watershed in the Westfield River watershed of the Connecticut River provides unique conservation opportunities based on the combination of intact forests and high-quality rivers and streams. This area offers one of the last and best opportunities for large-scale forest and aquatic system conservation in southern New England. The Nature Conservancy’s goal is to conserve the integrity of these forests and rivers both to protect the Connecticut River watershed as well as provide connectivity to other forested habitats in the Appalachians.

What TNC Has Done/Is Doing

From 2005 to present TNC has protected 16 tracts of land.




The Preserve’s habitats vary from rocky, hemlock-dominated forest, to shrubby wetlands and a cold water stream and shallow lakes. It also boasts a broad array of wildlife, including moose, bear and bobcat. There is a network of unmaintained woods roads that make for great walking, snowshoeing or cross-country skiing.
