Active Spread

Onondaga County confirmed SLF in 2022, placing Syracuse at the center of upstate New York's SLF spread corridor. The I-81/I-90 junction β€” the biggest freight hub in Upstate NY β€” accelerates SLF dispersal in all directions. The Erie Canal heritage corridor provides Tree of Heaven habitat connecting Syracuse to the broader state canal trail system. SUNY College of Environmental Science and Forestry (SUNY ESF) is an active SLF research partner, providing on-the-ground monitoring and public education across the region.

Primary SLF food source

Tree of Heaven in Syracuse, NY

The I-81/I-90 interchange is one of the most significant SLF spread nodes in upstate New York β€” heavy freight traffic and dense Tree of Heaven in highway corridors create ideal conditions for egg mass dispersal. Onondaga Lake Parkway and the Erie Canal trail have established TOH populations providing prime SLF habitat. SUNY ESF and Syracuse University campus greenspaces are under active monitoring as part of regional SLF research partnerships. Green Lakes State Park is a priority watch site.
