Knox County confirmed SLF in 2021, making Knoxville one of the earliest Tennessee confirmations. The Tennessee River corridor provides ideal Tree of Heaven habitat running through the urban core. University of Tennessee campus and arboretum are under active monitoring. The I-75 corridor from Kentucky β€” a fully established SLF state β€” is the primary introduction vector. Knoxville also serves as the gateway to Great Smoky Mountains National Park, where the National Park Service is actively monitoring for SLF spread into sensitive mountain ecosystems.

Tree of Heaven in Knoxville, TN

The Tennessee River waterfront and Fort Loudoun Lake shoreline have established Tree of Heaven populations supporting SLF colonies through Knoxville's urban core. UT campus arboretum and Ijams Nature Center are priority monitoring sites. The I-75 corridor from Kentucky brings continuous SLF pressure into Knox County. Tennessee wine country β€” including Winery at Seven Springs β€” faces growing risk as populations build throughout eastern Tennessee.
