Arboretum President and CEO Gerard Donnelly says road salt is—of course—an issue. He says his experts are helping the tollway select trees that can withstand the salt and the sometimes harsh conditions around heavy traffic.
“It’s really quite amazing to see how trees actually can survive some of these really unnatural conditions, and yet that’s where we really need them the most, where people are concentrating,” Donnelly tells WBBM Political Editor Craig Dellimore. “We need what trees can provide in those kinds of urban environments.”MORE NEWS: Keri Hilson Says 'Hip Hop Family Christmas' Is All About 'Honoring Your Family, Not Living For The World'
