Spotted Lanternfly inPeekskill, NYSPOTTED LANTERNFLY GUIDE
Peekskill — a Hudson River city of 24,000 in northern Westchester County — confirmed SLF in 2021. Undergoing an arts district revival anchored by Fleischmann's Pier recreation area on the Hudson, Peekskill sits at a critical ecological threshold: the transition from suburban Westchester County to the more rural and forested Hudson Highlands. The Metro-North Hudson Line station concentrates commuter traffic connecting Peekskill to New York City and the broader mid-Hudson Valley SLF zone. Blue Mountain Reservation and the Bear Mountain Interstate Park proximity corridor provide extensive forested habitat adjacent to the city, raising concerns about SLF spread into the Highlands. The Hudson River waterfront's Tree of Heaven populations are active SLF hotspots each season.

Tree of Heaven in Peekskill, NY
The Hudson River waterfront through Peekskill — including Fleischmann's Pier and Charles Point's industrial waterfront — has established Tree of Heaven populations providing prime SLF habitat along the river corridor. Blue Mountain Reservation's forest margins are a priority monitoring zone as SLF populations build at the Westchester-Hudson Highlands boundary — the forested transition into Bear Mountain State Park and the Appalachian Trail corridor represents a significant SLF spread risk into sensitive highland ecosystems. Metro-North Hudson Line station concentrates commuter vehicle traffic from NYC and the mid-Hudson Valley, accelerating SLF egg mass transport into northern Westchester County. Peekskill's arts district revival and waterfront recreation draw seasonal visitors that add additional vehicle-based spread pressure.
