Hydrilla

The highly invasive aquatic plant, Hydrilla verticillata, commonly known as 'hydrilla' or 'water thyme' was found in the Cayuga Inlet in 2011. The biotype that was found in the inlet is native to southeast Asia and was brought to the United States through the aquarium trade. Hydrilla was first found in the wild in Florida in the 1950's. It has since spread to many parts of the US. We will never know how hydrilla arrived in the Cayuga Inlet, but it was probably spread by a boater or someone dumping an aquarium irresponsibly.
