Located very near Main Street on Bars Avenue, this area of 7.89 acres was acquired in 7 parcels beginning with the purchase of the marsh itself in 1966. Subsequent purchases and gifts, the most recent in 2004, have added significant wooded upland to the holding, making it a well-balanced small ecosystem, supporting a wide variety of wild creatures. Not the least of these, a colony of red-winged blackbirds heralding the end of winter, and the much-appreciated chorus of spring peepers serenading the neighborhood in April.

The cattail marsh is at the intersection of Bars Avenue and Bay Lane.
