Park District Ash Tree Removal

The Emerald Ash Borer (EAB) is an invasive, non-native insect that feeds on and ultimately causes the death of the ash tree. The beetle is a metallic green in color and approximately one half (1/2) inches in length. The EAB was first discovered in the United States in Michigan in 2002 and is believed to have been transported to the United States from China on shipping crates.

Northbrook’s first confirmed case of EAB was found in the western part of the Village in May, 2011. Since then, additional locations have been confirmed.

The Park District has been proactive in its approach to the EAB. The District has been conducting visual inspections in looking for signs of activity and/or symptoms of the EAB. In 2009 the District conducted an extensive tree inventory that also rated the conditions of our trees.

The Park District began actively removing Ash trees last fall that were rated poorly or showed suspicious symptoms of EAB. That tree removal process will begin again in late September.

With assistance of an Urban Reforestation Grant through the Metropolitan Mayors Caucus, the Park District has been actively replanting the parks with a wide variety of trees. This year over 80 new trees will be planted.
