Learning About Invasive Species

In the Hudson River Valley, many invasive species plague our waterways, wetlands, and uplands. These fish, plants, and invertebrates are not native to our ecosystem and cause harm, often by out-competing native species or changing habitats. Usually invasive species do not have natural predators in the environment to which they are introduced, and their populations are able to grow, unchecked by predation!

Here at Clearwater, we are concerned about the many fish and plants that are invasive to our beloved Hudson River. On a sail with the Cary Institute for Ecosystem Studies, Clearwater’s Invasive Species Program Coordinator, Sam came aboard to teach passengers about Hudson River invasives.

Community members were engaged and asked lots of questions about what they can do to stop the spread of these organisms. One of the most proactive things boaters can do to stop aquatic invaders is, “Clean, Drain, Dry!” Most aquatic invasives spread via boating, so cleaning and draining your boat of water before entering a new waterway is imperative.

Sam also taught passengers about aquatic invasive plants like hydrilla. Passengers viewed examples of aquatic invasives displayed in our fish tank such as weather fish, goldfish, zebra mussels, and water chestnuts. It was a fantastic sail filled with learning, participation, and community education.
