LISLE, Ill. (January 22, 2014) – The Morton Arboretum’s Community Trees Program will be conducting five workshops across northern Illinois over the next few weeks aimed at helping municipal professionals responsible for tree care and management in their communities. The goal of the workshops is to both explore the impact of emerald ash borer and other invaders on area trees and also to examine ordinances and management plans critical to helping communities protect and maintain their trees.
