Invasives Plants Initiative
The presence and proliferation of invasive, non-native plants in the Connecticut River and other water bodies through the region and state has become a bigger and bigger issue in the past decade. Such non-native plants in the state have been identified going back decades. In many cases, the invasive plants take over and replace the native plants that are so important to the ecology of our waters. At present, our issues predominantly involve Hydrilla and Water Chestnut (Trapa natans), although Water Chestnut presence has been held at bay to the south of Middletown and Portland in the Connecticut River due to early detection and intervention of RiverCOG and numerous other partners the Mattabassett (the floating meadows) between Cromwell and Middletown still remains an area of serious concern despite the hard work of the Jonah Center and the River Conservancy and their many diligent and hardworking volunteers. Water Chestnut is easily controlled if gotten in its infancy, once established it can be eradicated but it does take years of concentrated diligent effort.
Hydrilla (Hydrilla verticillata)
In the summer of 2019, a river survey of the waters of the lower Connecticut River identified hydrilla and other invasives plants. The survey was conducted by a team of stakeholders including the Connecticut RC&D, RiverCOG, the Connecticut Agricultural Experiment Station (CAES), the Connecticut River Gateway Commission and the Eight Mile River Wild & Scenic organization.
