Spotted Lanternfly inGettysburg, PASPOTTED LANTERNFLY GUIDE
Adams County confirmed SLF in 2020. Gettysburg — the county seat and one of America's most visited heritage destinations — faces a unique convergence of SLF risk: 15 million visitors per year move through 6,000 acres of historically significant landscape at Gettysburg National Military Park, creating intense vehicle-based spread pressure. The Eisenhower National Historic Site adds further nationally significant grounds at risk. Adams County is Pennsylvania's number-one apple-producing county, placing the orchard industry at significant economic risk as SLF populations build through the region.

Tree of Heaven in Gettysburg, PA
Gettysburg Battlefield's historic tree stands are under documented SLF pressure — the same woodlands that witnessed the Civil War's pivotal engagement now face an invasive species threat. Tree of Heaven is established along Seminary Ridge and Cemetery Ridge tree lines and throughout the disturbed roadsides of the battlefield landscape. Adams County's apple orchard district — the largest in Pennsylvania — faces serious economic risk as SLF populations expand through the county. The National Park Service is actively monitoring SLF spread across Gettysburg NMP's 6,000 historically significant acres.
