The Emerald Ash Borer beetle is attacking Chicago's ash trees. At this informational session, residents will learn how to identify ash trees, determine whether beetles have infested their tree, and what steps can be taken to save the ash versus the cost of removal.

If left untreated, an ash tree is certain to die. Twenty percent of the trees in Chicago's parkways are ash trees.

John Friedmann of the Save Your Ash coalition and Michael Brown from the city's Bureau of Forestry are scheduled to present and answer questions. Tree service providers will also be on hand.

The meeting is scheduled for 7 p.m., April 24 at Lane Tech College Prep High School, 2501 W. Addison St. Enter from the parking lot on the south side of the building.
