|Expert Warns Against Emerald Ash Borer's Arrival
|You can't really destroy it, you can only hope to contain it.
That was the message that came out of a recent talk hosted by the City of Galesburg's Tree Commission on the Emerald Ash Borer.
The discussion was led by Dustin Hinrichs of the Iowa-based Trees Forever organization, which has been helping local governments in Iowa and Illinois get their hands figuratively around the tree-killing beetle that has been infesting trees primarily in Northern Illinois for years, but recently has spread as close as Stark County.
Hinrichs says many people just don't understand what an Emerald Ash Borer beetle can do to a tree.
"The larvae hatch and feel under the bulk of the bark of a healthy ash tree, and that's how they really cause the damage to the ash trees," Hinrichs said. "The larva themselves will spend and entire season in the cambium, slowly working their way around until they become adults. Then, they'll leave, find a new tree to drop their eggs off to host. It's a pretty viscous cycle."
Hinrichs says it can take anywhere from two to five years for EAB to kill an ash tree.
Hinrichs says there are chemical and other treatments, but they can be costly and time-consuming, so cutting down such trees and replacing them with other types of trees is probably the best alternative. He believes some communities have gone bankrupt trying to respond to an EAB outbreak.
