Emerald Ash Borer Management
Forest management is an important part of maintaining a healthy watershed since forests help to slow down runoff and filter out pollution. DEP foresters have been working with professionals from the United States Forest Service and the New York State Department of Environmental Conservation for several years on an initiative called Slow Ash Mortality (SLAM).
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. Working with Federal and State Agency partners they developed a plan to target larger trees near the edge of the infestation for harvest before they became infested and could pump out large numbers of new beetles. This strategy had been shown to be successful in keeping populations from expanding to new sites very quickly in the Midwest where the emerald ash borer infestation was discovered in 2002.
