Jamesburg Park Conservation Area was some of the first lands that Middlesex County acquired using Green Acres funding for open space protection in the early 1970’s. It protects both the underground resources of the Old Bridge Sands aquifer, and a unique pine barrens habitat in Middlesex County.
Jamesburg Park Conservation Area lies within the Spotswood Outlier—the northernmost area of New Jersey Pine Barrens habitat. Along the several miles of trails you can find typical Pine Barrens species—pitch pine trees, blueberries, huckleberries and post oaks. The wetlands protect Atlantic white cedar trees and carnivorous pitcher plants. Several endangered and threatened species of plants and animals have been observed in this preserved open space
Jamesburg Park would have been very different if the proposed development had come to fruition. In the early 20th century , visitors were brought by train from New York to enjoy Saturday night dances and purchase land in the countryside of New Jersey. While the development never came to be, you can still find sidewalks in the woods showing where the streets were meant to run. Cranberry bogs covered some of the wetland areas, and the waters from Jamesburg Park Conservation Area were used by the nearby Helme Snuff mill.
