Spotted Lanternfly inGreene County, NYSPOTTED LANTERNFLY GUIDE
Greene County sits at the northern edge of the Catskill Mountains, confirmed for SLF at moderate density in 2022. Catskill village — the county seat on the Hudson River — serves as the primary population center and SLF monitoring hub for this largely rural county. The county's ski resort communities at Windham and Hunter Mountain generate significant out-of-state vehicle traffic throughout the winter season, creating ongoing freight-mediated spread risk as vehicles arrive from established SLF zones in New Jersey and the lower Hudson Valley. Kaaterskill Clove — a dramatically beautiful and ecologically fragile gorge that inspired the Hudson River School of painting — is a priority monitoring zone where SLF establishment would threaten a uniquely sensitive landscape.

Tree of Heaven in Greene County, NY
Tree of Heaven is established along the Catskill Creek corridor and Hudson River waterfront margins in Greene County, creating SLF habitat pathways from the river into the Catskill Mountain foothills. The Rip Van Winkle Bridge approach roads and Route 23 commercial corridor have Ailanthus populations that extend SLF dispersal habitat through the county's primary vehicle corridors. Kaaterskill Falls area road margins and the Windham and Hunter ski resort access roads are priority monitoring zones as out-of-state visitor vehicles represent ongoing SLF introduction risk throughout the ski season.
