Tree of Heaven in Youngstown, OH
Mahoning River banks through Youngstown support established Tree of Heaven populations that are primary SLF habitat and dispersal corridors. Abandoned steel mill sites throughout the city are among the most prolific Tree of Heaven colonization zones in northeastern Ohio, creating concentrated SLF habitat in the urban core. The I-80 Ohio Turnpike running through the region is a documented SLF spread pathway moving infested vehicles and freight across the state.
