Representatives of Greening UToledo Through Service Learning (GUTS) and the Jesup Scott Honors College, among other organizations, came together Friday, Oct. 31, in a shared effort to remove tree of heaven, a host plant for the invasive spotted lanternflies that were readily identifiable on campus this summer.

GUTS is facilitating removal efforts this fall as a service-learning opportunity.
