ALBANY, N.Y. (AP) _ New York state is now requiring boaters to clean their watercraft to fight the spread of invasive species.
Gov. Andrew Cuomo signed legislation Tuesday that instructs boaters to clean, drain and dry their boats to ensure they're not inadvertently transporting invasive plants or animals into a body of water.
The governor's office says invasive species are ``one of the greatest threats'' to the state's lakes and waterways because they can out-compete native plants and animals and alter entire ecosystems.
The state's Department of Environmental Conservation says invasive species cost the national economy an estimated $120 billion a year.
