Spotted Lanternfly inLuzerne County, PASPOTTED LANTERNFLY GUIDE
Luzerne County — with Wilkes-Barre as county seat — was confirmed for SLF in 2018 and is the most populous county in the Wyoming Valley, Pennsylvania's northeastern anthracite coal heartland. The Susquehanna River corridor running through the broad Wyoming Valley floor provides a natural SLF spread highway connecting populations from the south northward toward Scranton and beyond. Wilkes-Barre's dense urban core and the I-81 freight corridor make the county a critical node in regional SLF spread. The county's anthracite heritage landscape — with mine sites, canal remnants, and rail corridors — has created extensive Tree of Heaven colonization across disturbed industrial lands that fuel SLF establishment throughout the valley.

Tree of Heaven in Luzerne County, PA
Tree of Heaven is well established along the Susquehanna River waterfront and Wyoming Valley floor road margins in Luzerne County, providing primary SLF dispersal pathways through this broad valley corridor. The I-81 road margins and former anthracite rail corridors through Wilkes-Barre have dense Ailanthus populations on disturbed industrial lands that fuel SLF establishment in and around the urban core. Coal heritage site margins and the river waterfront greenway are priority monitoring zones as SLF populations continue to expand through this historically significant northeastern Pennsylvania landscape.
