Experts Gather to Discuss Aquatic Invader, Hydrilla


Scientists and resource managers from around the Northeast, Mississippi and Florida met in Syracuse, N.Y., on September 11-12 at the Northeastern Hydrilla Symposium. Hydrilla is an extremely invasive aquatic species from Asia that was introduced in the 1960s into the southern United States. The symposium was sponsored and hosted by the U.S. Army Corps of Engineers Buffalo District and the Corps’ Engineer Research and Development Center (ERDC) in Vicksburg, Miss., in cooperation with federal and state resource managers from the Northeast. The symposium was held in response to the recent discovery of Hydrilla in the Cayuga Lake Inlet in Ithaca, NY, in New York’s Finger, which has caused growing concern about the spread and introduction of Hydrilla throughout the northeastern United States.

The intent of the symposium was to help direct future research and Hydrilla eradication and management technology development, and to share lessons learned on Hydrilla management strategies. Approximately 40 resource managers, industry professionals, and researchers from eight states throughout the Northeast, including New York attended the symposium. Experts from southern states and universities also shared their expertise.

Hydrilla, if not controlled quickly and made the target of rigorous early detection and eradication programs, could spread beyond the Cayuga Inlet into the Seneca-Cayuga Canal, the Erie and Barge Canal systems, and other lakes and rivers in New York, including the Great Lakes, leading to millions of dollars of ecological damage, recreational impacts, and lost property tax revenue.
