Invasive Species

We take the threat of invasive species very seriously. We’re working to prevent the introduction of new invasive species to our water supply lands by supporting early detection and rapid response to emerging invasive species of concern and efforts to control existing invasive species problems.

Hydrilla Management
Hydrilla is a uniquely disruptive plant because it can grow in practically all conditions, harm a wide range of natural resources and obstruct the operation of drinking water infrastructure.

Emerald Ash Borer Management
When the emerald ash borer—a small green beetle from Asia that only attacks ash trees—was first found in the watershed in 2010, DEP foresters knew that it would only be a matter of time before all of the ash trees were lost.

Asian Longhorned Beetle
The Asian longhorned beetle has an appetite for maple trees and a number of other of hardwood trees and can feast its way to total forest destruction.

Aquatic Invasive Species Prevention
Aquatic organisms like the spiny water flea, hydrilla, and zebra mussel have the potential to negatively impact water quality, limit recreation opportunities, and increase the cost of delivering clean drinking water.

Early Detection / Rapid Response Planning
Finding invasive species early generally allows you to conduct a “rapid response,” or to control the small population, eliminating it quickly before it becomes too difficult or costly to control.
