(SOUTH BEND) - Dozens of trees on the University of Notre Dame campus are being chopped down because they've been infected by the tree-killing emerald ash borer.
St. Mary's Road through the South Bend campus has a line of stumps along it where until recently it was lined with 30-year-old ash trees.
University spokesman Dennis Brown says that 30 trees have been cut down in that area, with perhaps 40 more to be removed later this fall. More than 100 ash trees have been removed from the campus over the last five years.
The ash borer is an insect native to Asia that has killed tens of millions of trees in the Northeast and Upper Midwest since 2002. The beetle was first found in Indiana in 2004.
