The Emerald Ash Borer has invaded the campus and nd the University must make a decision to cut down or treat hundreds of trees.
The Emerald Ash Borer can kill a tree within two to three years of infection.
Over 400 ash trees are scattered around ISU's campus, and already maintenance crews have treated 180 and cut down at least 80 trees.
Stephanie Krull, ISU Landscape and Grounds Manager says, "More than anything we are doing our treatment as a cost saving and impact mitigation, so that it's not quite as drastic so we don't lose all the trees at the same time."
Crews are growing other species of trees off campus to replace the Ash Trees.
