Why these 20 trees had to be dug up

Monday, July 14, 2014   by: Staff



Lake Superior State University physical plant workers Ron Throener (in distance, red pants) and Shane Hubbard (operating backhoe) dig up upwards of 20 trees from in front of Crawford Hall that had been killed by the emerald ash borer.

Crews planted more than 40 large-caliper maple, oak, and flowering crab apple trees to replace those they took down on July 8.

These tree types are impervious to the invasive insect that is wiping out ash species throughout North America.

LSSU has planted more than 75 trees around campus over the past seven years to replace diseased or dead trees.

Contaminated wood is being quarantined to keep the ash borers from spreading any farther than they've already gone.
