Watch Zone

DeKalb County forms the eastern half of the core Atlanta metro and is under watch zone monitoring as SLF advances southward along the I-85 corridor through the Southeast. The county's diverse mix of dense urban neighborhoods, suburban corridors, and significant international communities in Clarkston create both high-traffic introduction risk and important community outreach opportunities. I-285 bisects the county and carries enormous freight volumes from SLF-infested states in the Northeast and Mid-Atlantic. The South Fork Peachtree Creek and Snapfinger Creek corridors provide riparian habitat that could sustain early SLF populations. Georgia Dept of Agriculture has placed DeKalb on priority monitoring status given its direct highway and rail connections to confirmed SLF zones farther north.

Primary SLF food source

Tree of Heaven in DeKalb County, GA

Tree of Heaven is present along the I-85/I-285 Atlanta perimeter, CSX and Norfolk Southern rail lines, and along stream corridors in the South Fork Peachtree Creek drainage through Decatur and Tucker. Chamblee and Dunwoody road margins along rail rights-of-way harbor Ailanthus populations that would serve as initial establishment sites for any SLF introduced via freight or vehicle transport.
