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 block out the native plants that are so important to the ecology of our waters.  At present, our issues predominantly involve Hydrilla and Water Chestnut, although Water Chestnut presence has been held at bay in the southern part of the Connecticut River due to the diligent work of RiverCOG and numerous other partners.

Hydrilla (Hydrilla verticulata)

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.
