The Silvio O. Conte National Fish and Wildlife Refuge and its many partners and volunteers have completed a sixth very successful field season helping citizens throughout the Connecticut River watershed protect their aquatic ecosystems from the invasive aquatic plant water chestnut (Trapa natans). With financial support from the Secretary of Interior’s Cooperative Conservation Initiative, a 20-acre infestation at Log Pond Cove in Holyoke, Massachusetts was prevented from setting seed by machine harvesting where the water was deep enough and with herbicide in shallow areas. In addition, the refuge enlisted 134 volunteers and cooperators, who spent 700 hours handpulling 25 tons of the plant, clearing the 28 water bodies where it is known to occur in the Ct. River watershed in Connecticut, Massachusetts, and Vermont.
