Oswego, NY, August 15, 2013 - An Aquatic Invasive Species (AIS) is an organism introduced to an ecosystem that disrupts the native habitats of the region.  These organisms are spread a number of ways including accidental dispersal by humans.  AIS are becoming a persistent problem for waterways in New York State (NYS), clogging boating channels, disrupting the natural food webs, and impacting taxpayers.  

The impacts of AIS on local economies include AIS management costs, and the potential to decrease shoreline property value.

According to a study by the Anderson Economic Group, AIS have a huge economic impact on the Great Lakes region.  The study states that it is “likely that the overall aggregate level of cost (to industry, consumers, and government) to the Great Lakes region is significantly over $100 million annually.”  

The economic weight of AIS has been felt locally.  In 2011, Hydrilla, an aquatic invasive plant, was discovered in the Cayuga Lake inlet in Ithaca, NY.  Hydrilla posed three main problems to the economy of the surrounding area: hindering boating experiences, compromising flood control measures, and lowering property tax revenues.
Efforts to suppress the waterweed have proved to be effective, yet costly.  James Balyszak, project manager of the Hydrilla Task Force of the Cayuga Lake Watershed, states that the project is currently in year three of a ten-year plan and estimates the expenses of the Hydrilla removal project at $400,000 for 2012. Balyszak expects the cost to remain in the $400,000 to $500,000 range per year for the remainder of the project.

AIS can adversely affect recreational activities, such as boating, fishing, swimming; lower the overall aesthetics of a property; and have the potential to decrease shoreline property value.  

There is no definitive estimate for the impact AIS have on property values, however, heavy growth of aquatic weeds, including AIS, can decrease shoreline property values by up to 20 percent, says Invasive Species Specialist Chuck O’Neill with Cornell University Cooperative Extension, Ithaca, NY.  O’Neill stresses that “even a 10 percent drop in waterfront property values can be a big hit to a local community.”

Suppressing AIS to maintain water and habitat quality is tough work.  NYS residents can watch for opportunities to participate in local citizen programs, such as water chestnut pulls.  Educational outreach programs, such as the New York Sea Grant Launch Stewards Program, are a valuable source of information about AIS, prevention measures, and management efforts for coastal residents, boaters, anglers, municipality leaders, and service groups.
Shoreline property owners and recreational users can be proactive in protecting their own property from AIS and the associated costs.  To help in the effort to reduce the impacts of AIS on private property and public recreational areas, report any new AIS plant or animal to your local Partnership for Regional Invasive Species Management (PRISM) coordinators; find offices via  

Those who fish, boat, kayak and canoe are advised to inspect their watercraft and equipment after every use and properly discard any aquatic hitchhiking organisms or debris or collect a specimen for identification by iMapInvasives and/or local PRISM experts.

Help nip AIS in the bud before they nip us in the pocketbook.

More Info:

New York Sea Grant (NYSG), a cooperative program of Cornell University and the State University of New York, is one of 33 university-based programs under the National Sea Grant College Program (NSGCP) of the National Oceanic and Atmospheric Administration (NOAA). The NSGCP engages this network of the nation’s top universities in conducting scientific research, education, training and extension projects designed to foster science-based decisions about the use and conservation of our aquatic resources. Through its statewide network of integrated services, NYSG has been promoting coastal vitality, environmental sustainability, and citizen awareness about the State’s marine and Great Lakes resources since 1971.

For updates on Sea Grant activities: has RSS, Facebook, Twitter, and YouTube links. NYSG also offers a free e-list sign up via for NY Coastlines, its flagship publication, and Currents, its e-newsletter supplement, each distributed several times a year.
