Spotted Lanternfly inBerkeley County, WVSPOTTED LANTERNFLY GUIDE
Berkeley County is West Virginia's Eastern Panhandle powerhouse — the most populous county in the panhandle, confirmed for SLF as early as 2017 — among the first West Virginia counties affected. Martinsburg, the county seat, sits directly on the I-81 corridor, the primary northeast-southwest freight highway connecting established SLF zones in Virginia, Maryland, and Pennsylvania to the broader mid-Atlantic. The MARC commuter rail line connects Berkeley County directly to Washington DC and its suburbs, providing a daily human-movement vector that reinforces SLF populations through commuter traffic from heavily infested DMV counties. Berkeley County's rapid suburban growth as a DC exurb means new residential development constantly opens fresh SLF habitat, and the Winchester-Martinsburg I-81 freight zone is one of the most active SLF reinforcement corridors in the entire Eastern Panhandle.

Tree of Heaven in Berkeley County, WV
Tree of Heaven is established along the I-81 corridor and Opequon Creek watershed margins throughout Berkeley County, creating continuous SLF dispersal pathways connecting the Virginia and Maryland infestation zones into the West Virginia Eastern Panhandle. Martinsburg commercial district road margins and the MARC rail corridor have Ailanthus colonization that supports SLF establishment in the county's most trafficked zones. The rapidly expanding suburban fringe of Berkeley County has ToH in disturbed construction margins and undeveloped lots — a classic SLF establishment pattern in fast-growing DC exurban counties.
