Spotted Lanternfly inJim Thorpe, PASPOTTED LANTERNFLY GUIDE

Lehigh Gorge State Park's dramatic gorge walls and rocky slopes are prime Tree of Heaven colonization terrain — disturbed cliff faces and gorge edges with full sun exposure allow TOH to dominate, creating dense SLF habitat running through one of Pennsylvania's most visited natural landscapes. The Delaware & Lehigh Trail corridor has established TOH along its former railroad right-of-way, providing continuous SLF habitat connecting Jim Thorpe to the broader Carbon County and Lehigh Valley infestation zone. The historic downtown's massive weekend tourist vehicle traffic from Philadelphia and NYC metro — particularly heavy in spring through fall — creates a major recurring SLF egg mass export event, as visitors depart with egg masses on their vehicles to home regions throughout the mid-Atlantic.
