The proliferation of invasive plants such as water chestnut and hydrilla in the Connecticut River, its tributaries, and local ponds has led to more common use of EPA-approved herbicides by government agencies such as the U.S. Army Corps of Engineers (USACE) and the U.S. Fish and Wildlife Service (FWS).
The Jonah Center has asked these agencies, and others, for advice on how best to manage the water chestnut infestation in the Mattabesset River (Floating Meadows). The message we have heard is consistent. Hand-pulling is best where it is feasible. But there are some shallow areas with dense, stubborn infestations where hand-pulling by paddlers is not effective. Such areas represent a small percentage of the total surface area, but the seeds from these remote patches keep germinating in deeper areas, producing more patches that hand-pullers face each year. Every year, the seed bank in these coves and creeks grows. Continue reading
