During the last thunderstorm, a number of the larger and older trees in the community fell. There were more trees than we normally have fall from storms and there is a reason why.
The dreaded emerald ash borer has invaded our community. Back in May 2013, Mr. Jim Prendergast of the Kineo Group came out to the Park Manor Neighbors Community Council (PMNCC) meeting and explained the effects this insect is having on the Ash tree population in the community. It is estimated that over 60% of the Ash trees in Park Manor/Chatham are infected and will die in 5 years if not treated.
The Emerald Ash Borer (EAB) is an exotic woodborer that was found to be attacking and killing ash trees in Michigan in 2002. The Emerald Ash Borer only attacks ash trees and is a devastating and destructive pest that greatly affects the urban forest. EAB is easily spread through the movement of firewood, logs and nursery stock.
In Chicago, ash makes up around 19% of the City’s street tree population or about 97,000 trees. When adding an estimated 500,000 ash trees from private property to the total, ash trees become one of the most numerous trees in the City.
In an effort to prevent EAB from being introduced to Chicago, the Bureau of Forestry prohibited the planting of ash on the public right-of-way beginning in 2003. The Bureau of Forestry is currently surveying ash trees in search for the EAB. If you suspect you have emerald ash borer please call 311 or the beetle hotline, 312-74BEETL (312-742-3385)
