In 2002, scientists at the Connecticut Agricultural Experiment Station (CAES) began surveying Connecticut lakes and ponds for invasive aquatic plants and investigating novel management options. Surveillance focuses on both invasive and native vegetation to quantify the effects of invasive species on aquatic ecosystems. This research allows us to track the spread and record the arrival of invasive aquatic plants. Surveys also provide baseline information to determine if the frequency and magnitude of invasions may be related to water chemistry, sediment type, boat launches, watershed development and climate change. Management studies include tests on the effectiveness of herbicides, mechanical removal, water level manipulation, biological control, and integrated pest management. In 2022, the Office of Aquatic Invasive Species (OAIS) was established and was provided additional State funding. CAES OAIS research is conducted through the support of the United States Department of Agriculture (USDA) HATCH funds, CT DEEP, and private supporters.
