Spotted Lanternfly inColumbia County, NYSPOTTED LANTERNFLY GUIDE
Columbia County is a rural Hudson Valley county with an outsized arts and cultural identity — Hudson City, the county seat, has become a destination for galleries and tourism, while the surrounding landscape of farms, woodlands, and creek corridors provides extensive SLF habitat. Confirmed in 2022, SLF populations are establishing at moderate density across the county. The Columbia Land Conservancy is actively monitoring SLF spread through conserved agricultural and forest lands. A growing wine scene — including Tousey Winery and Hudson-Chatham Winery — faces the same pressures from SLF that have threatened Hudson Valley viticulture to the south. Catamount ski area and the Claverack Creek watershed are additional key monitoring zones.
