Tree of Heaven in Towson, MD
Loch Raven Reservoir's watershed margins have established Tree of Heaven populations creating prime SLF habitat through Towson's surrounding forested corridors. The I-695 Beltway is a major SLF dispersal vector — high-volume freight and commuter traffic moves egg masses around the entire Baltimore metro ring road. Cromwell Valley Park stream corridors and Towson University's campus tree canopy add additional TOH habitat sustaining large SLF colonies through Baltimore County's administrative center.
