Tropical Storm Irene is still affecting Vermonters. Now it is an invasion of the Japanese knot-weed which is erodes the riverbanks. During the flooding, many pieces tore loose and are scattered throughout the state.
Brian Colleran an employee of the State of Vermont has the task with locating and working to eliminate the new infestations. Established knot-weeds take 3-5 years to kill, but new infestations are easy to remove.
