Constitution Trail – Ash Tree Replacement Project

The City of Bloomington Parks, Recreation, & Cultural Arts Department has received an Illinois Urban Forestry Restoration Grant through the Department of Agriculture to remove and replace 96 Ash trees along the Bloomington portions of Constitution Trail.

These funds will provide a unique opportunity to reforest the park after the impending loss of Ash Trees caused by the Emerald Ash Borer and will also increase the diversity of tree species throughout the park.

96 trees were removed and an equal number were replanted in the spring of 2012. Trees with a diameter of 8" or more will be utilized for lumber.

Any questions, please contact the Parks Division at (309) 434-2280


Emerald Ash Borer

The Emerald Ash Borer (EAB) is a small green metallic beetle approximately 1/2 inch long. The EAB was first discovered in Canada in 2002 and since has done extensive damage to ash populations in Michigan, Indiana, Ohio and now Illinois. The EAB poses no threat to animal or human health. Over 30 million ash trees in the Midwest have been lost to EAB. EAB attacks only trees in the genus fraxinus. These are the white, green, blue and black ash. The majority of ash trees in Bloomington are green or white ash. For more information on EAB in Illinois go to www.illinoiseab.com.

Emerald Ash Borer

In July of 2008 the State of Illinois Department of Agriculture (IDOA) notified the City of Bloomington that 2 adult EAB beetles had been found in traps on the southwest side of town. City staff are working cooperatively with the IDOA and USDA to determine the extent of the EAB infestation. Illinois is under a federal EAB quarantine and McLean County is under as state quarantine as of November 1st, 2008. The quarantine is designed to help slow the spread of EAB once it is discovered in an area.

 

Citizens can take several steps to help slow the spread of the EAB throughout the county:
  • Do not move firewood.
  • Burn all firewood by April 30th of each year.

Chemical Treatment
There are currently 2 chemical treatments available for EAB. The treatments range in effectiveness with the health and condition of tree and extent of infestation. Currently there is no 100% effective chemical control of EAB and when considering chemical treatment one should balance the costs of annual treatments over time versus replacement and removal costs. Treated ash trees may still need to be removed in the future. To help in identification of your trees consult www.plants.usda.gov.

The Forestry Division is actively surveying the ash trees on city property and removing infested trees on a hazard first basis. Any ash tree removed will be replanted with an alternate species provide ample space is available. If you would like to report an infested ash tree on public property, please call 434-2260.
