Spotted Lanternfly inWarren County, NYSPOTTED LANTERNFLY GUIDE
Warren County is the Lake George tourism hub of the southern Adirondacks — entered the SLF watch zone in 2023 as populations advanced northward along the I-87 Northway corridor from the established Capital District. Lake George village is one of the most visited resort destinations in New York State, drawing enormous seasonal tourist vehicle traffic from the heavily infested Hudson Valley, New York City, and New Jersey metro areas throughout the summer season. Gore Mountain ski resort generates additional high-volume vehicle traffic from established SLF zones during the ski season. The county sits at the southern gateway to Adirondack Park, one of the largest protected wilderness areas in the eastern United States, making SLF establishment here a significant concern for the long-term ecological integrity of the Adirondack region.

Tree of Heaven in Warren County, NY
Tree of Heaven is present along the I-87 Northway corridor and road margins in southern Warren County, providing the primary SLF dispersal pathway from the established Saratoga County watch zone northward into the Lake George region. The Lake George village resort corridor and Gore Mountain access roads are priority monitoring zones where the concentration of out-of-state tourist vehicles from heavily infested metro areas creates continuous SLF introduction risk through the summer and winter seasons. Lake George Battlefield Park margins and the Adirondack Park gateway approach roads are additional high-priority monitoring sites as SLF approaches the boundary of New York's most ecologically protected landscape.
