Spotted Lanternfly inCleveland, OHSPOTTED LANTERNFLY GUIDE
Cuyahoga County confirmed SLF in 2022, placing Cleveland at a critical northeastern Ohio watch zone. The Lake Erie waterfront, Cuyahoga River valley, and the Metroparks "Emerald Necklace" system of forested reservations encircling the city represent prime SLF habitat corridors. The I-71/I-77/I-90 interchange — one of the busiest freight intersections in the Great Lakes region — is a major vehicle-based dispersal vector. Greater Cleveland RTA's rail network and Case Western Reserve University campus add additional spread and monitoring concerns.

Tree of Heaven in Cleveland, OH
The Cuyahoga River valley — historically significant as an industrial riverway — has established Tree of Heaven populations along its banks running through the urban core. Cleveland Metroparks' "Emerald Necklace" forest reservations, totaling over 23,000 acres encircling the city, are at risk as SLF pressure builds in Cuyahoga County. The I-71/I-77/I-90 interchange concentrates freight traffic with highway margin TOH. Case Western Reserve University and Cleveland State University campuses are active monitoring sites.
