Project Hightlight: Croton River Hydrilla Control

We couldn't be happier with the success the Department of Environmental Conservation has had with the first year of hydrilla control on the Croton River!

Back in 2013, a rare plant surveyor found the infestation of Hydrilla verticillia, an agreesive aquatic invasive plant, in the river.  To determine the extant of the invasion, the Lower Hudson Partnership for Regional Invasive Species Managment (LHPRISM) contracted Allied Biological, Inc. to survey and find out how much it had spread. The DEC began treatments this year using low concentrations of the herbicide fluridone and concluded them at the end of October. 

With no other rooted hydrilla found in the Hudson River or other estuaries, it is critical that we get this plant under control before it spreads further. Over the next 4 years, additional treatments will continue to promote the health of the river and protect our local biodiversity.
