The Emerald Ash Borer was discovered in Illinois in 2006. Four years later, it was discovered in Lisle. The Emerald Ash Borer is an exotic beetle whose larvae feed on the inner bark of ash trees. This disrupts the tree's ability to transport nutrients and water to the tree, which causes it to die. This beetle only targets ash trees. Millions of ash trees have already been lost in the Midwest from damage from the Emerald Ash Borer.
Ash Tree Removal Program
Since 2008, the Village has been following the recommendations of the Illinois and Federal Departments of Agriculture. These recommendations included vigilant inspection, treatment and removal of the infested ash trees. At this time, the Village has decided to remove all remaining public ash trees from the parkways.
Should the parkway in front of your property contain an ash tree, it will be removed between May 1, 2015 and August 31, 2015. The Village has contracted with Steven Piper & Sons to remove all the remaining ash trees in the parkways. Affected residents will be sent a letter which reviews the process in detail.
Scope of the Program
The Village of Lisle has 950 ash trees left in its inventory. The entire remaining Village owned ash trees are scheduled to be removed by August 31, 2015. The work will involve removing the trees, grinding of the stumps, debris disposal, top soil placement to fill in the stump holes, seeding of the top soil and installation of erosion control blankets. The removal activity is permitted Monday through Friday, 7 a.m. to 3:30 p.m. There is a possibility that some work activities may occur outside of this timeframe if the contract if given approval from the Public Works Department.
The Village will begin an aggressive planting program to help rebuild Lisle's urban forest. While 1,042 trees will be removed due to Emerald Ash Borer destruction, not all of them can be replaced due to the spacing and location of old stumps and existing trees. Replacing trees will also depend upon availability of stock from nurseries as there are many towns working on similar removal/planting programs at this time.
Status Update, July 1, 2015 The Village's removal contractor is finishing up work in the north section of town and is starting to remove trees in the middle section of town (BNSF tracks to Maple Avenue). In late July/early August, tree removal will take place in the southern section of town (Maple Avenue to Sun Valley).
New trees are currently being planted in the north section of town; 45 trees should be planted daily, weather permitting until 376 trees have been planted in this section. New tree planting will continue through the fall.
An erosion blanket is being used in the restoration areas. The blanket and new grass can be mowed once the grass reaches four inches. The blanket will be chopped up and will disintegrate. It is best not to pull up on the blanket as the new seedlings are growing into it and can be pulled from soil. Questions

We have begun planting today in the section of town north of the BNSF tracks. We cannot always do a 1 for 1 replacement due to spacing and location of old stumps and existing trees.
376 trees are going back into this section. Weather permitting, about 45 trees will be planted daily.
We will continue to try to replace trees throughout the summer and fall, once the Ashes are removed. Replacements and schedule will be based on availability.
