  • A Eurasian milfoil plant floats just beneath the surface in Mascoma Lake in Enfield, N.H., on July 11, 2014. The plant is an incredibly persistent invasive species brought to the lake as a hitchhiker on traveling boats. Small fragments of milfoil have the ability to take root and become full-developed plants, making complete removal from the lake practically impossible. (Valley News - Will Parson)

Bud and Terri Lynch and David Kelman, who are members of the Mascoma Lake Association, are part of a volunteer effort to monitor and combat the invasive plant Eurasian milfoil from growing in the lake. Eurasian milfoil can exclude native species in the shallow water where it lives, and lakes with introduced milfoil experience decreased property values. Mascoma Lake is part of a 195-square-mile watershed that feeds into the Connecticut River.
