ROTTERDAM — The Plotter Kill Preserve will be closed from Oct. 23-25 while the state Department of Environmental Conservation fights an invasive species there.
The DEC plans to being applying pesticide in the park to kill the hemlock woolly adelgid, a tiny insect native to Japan that can pose significant harm to the forest ecosystem, according to the DEC.
The adelgid was recently discovered in the Plotter Kill and in the Indian Kill Preserve in Glenville.
Weather permitting, certified pesticide applicators will begin treatments in the Plotter Kill the week of Oct. 23.
Signs will be posted at preserve parking lots, and public access will be restricted during the treatment period. In the event of rainfall during the application period, the work will be postponed to Nov. 1-3.
The recommended treatment is the use of systemic insecticides applied to the trees. The two chemicals most commonly used for HWA management, imidacloprid and dinotefuran, have not been shown to have adverse health or environmental impacts at exposures that will occur with this treatment program, according to the DEC.
