LAWRENCE, Kan. (AP) - The University of Kansas has tentative plans to try and save some notable ash trees on its campus from the invasive beetle known as the emerald ash borer.

According to a draft of the University of Kansas’ ash tree management plan, about 20 trees that are in significant locations on campus would be injected with insecticide to prevent ash borer infestation.

The Lawrence Journal-World (https://bit.ly/28KeJLu ) reports that trees left untreated would be monitored for signs of infestation. Diseased or distressed trees would be removed. The plan also calls for replacing ash trees with other species over five years.

The University of Kansas Facilities Services would carry out the management plan.

The ash borer feeds on tree tissue beneath the bark, destroying the ability to move water and nutrients to branches. Scientists believe the ash borer was accidentally introduced into North America in the 1990s, most likely in wooden shipping crates from Russia, China, Japan or Korea.

Jeff Severin, director of the University of Kansas’ Center for Sustainability, coordinates the campus tree advisory board.

“Our trees provide a shaded walk on an otherwise sunny hilltop campus,” Severin said. “We have a significant number of ash trees, and some clustered in very prominent places. But the loss provides us an opportunity to replant, building greater plant diversity and resistance to disease and drought, and to continue providing the landscape and campus experience Jayhawks have treasured for decades.”
