Tompkins County confirmed SLF in 2021, placing Ithaca at the forefront of SLF's spread into upstate New York. Cornell University is ground zero for North American SLF research — the A.C. Morrison Lab leads national containment and biocontrol efforts. The Finger Lakes wine region faces major economic risk as SLF populations build, and the famous gorges and waterfalls corridor provides ideal Tree of Heaven habitat along stream banks.
