Spotted Lanternfly inBucks County, PASPOTTED LANTERNFLY GUIDE
Bucks County is one of Pennsylvania's earliest infested counties — confirmed in 2015, just one year after ground zero Berks County — and has endured over a decade of SLF establishment. The Delaware River corridor directly connects Bucks County populations to New Jersey via bridges at New Hope and other crossing points, making it a critical bi-state spread node. The New Hope wine and arts district, Doylestown area, and the Delaware Canal State Park face sustained SLF pressure, and major suburban sprawl pushing into agricultural land has created a complex monitoring landscape across the county.

Tree of Heaven in Bucks County, PA
Delaware Canal State Park in Bucks County is a textbook SLF corridor — Tree of Heaven lines the historic canal towpath for miles along the Delaware River, creating a continuous Ailanthus highway that SLF populations exploit throughout the summer and fall seasons. New Hope riverfront and Route 202 commercial corridor margins have additional dense ToH populations that fuel year-round SLF establishment. Peace Valley Park and Nockamixon State Park area road margins are additional high-priority monitoring zones.
