Emerald Ash Borer in Schaumburg

About the Emerald Ash Borer (EAB)

Discovered in 2002 in Michigan, the Emerald Ash Borer (EAB) probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. In the larvae stage, EABs feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients.

The canopy of infested trees thin above infested portions of the trunk and major branches because the borer destroys the water and nutrient conducting tissues under the bark. An infested ash tree will usually die after a few years of noticeable decline. In fact, in less than 10 years, the EAB has killed millions of ash trees throughout the Midwest. Through research efforts by major universities and experience in heavily infested communities, much has been learned about the Emerald Ash Borer since 2002.

Reforestation Plan

The reforestation planting schedule is designed to replace trees in the order that they were removed; trees removed early in the EAB Management Program will be replaced first. In an effort to expedite reforestation, the Village is continuing to offer 50/50 cost share to any resident that desires to have their tree planted sooner than what is otherwise scheduled.

If a resident desires to take advantage of the 50/50 cost share program, the resident shall pay 50% of the replacement cost for a standard 2.5” diameter tree. The program also provides an option for residents to increase the size of the replacement tree to a 4” diameter tree. Please note, 4” diameter trees have a lower survival rate due to the root systems regenerating at a slower rate. Residents requesting the 4” diameter tree will be required to pay the difference in cost between the standard 2.5” replacement and the larger size. The 4” diameter option will be subject to parkway size and tree availability. During certain planting seasons, the 4” diameter option may not be available at all. See the Cost Share Species and Cost for pricing and available trees.

Please keep in mind that the tree supply in northern Illinois is very low and some species may not be available in the sizes or quantities needed for the 50/50 cost share program. Also, we ask that you provide a 1st selection and 2nd selection when ordering trees through the 50/50 Cost Share Program to increase the chances that a tree of your choice will be available. In addition, it may be necessary to move your tree to the next planting season due to availability. If this occurs, you will be notified by the Village Forester.

Spring 2018 Cost Share

Cost Share reforestation planting is scheduled to begin again in May, 2018, to replace Ash trees in the order that they were removed.  In an effort to expedite reforestation, the Village is continuing to offer a cost-share option to any resident that wishes to have their tree planted sooner than what is otherwise scheduled. If a resident desires to take advantage of this program, the resident shall pay a percentage of the replacement cost for an approximately 2-inch diameter tree.  Participants will receive a letter in the mail requesting their first and second selections when ordering trees to increase the chances that a tree of your choice will be available. 

Please make a Customer Service Request or call 311 to request participation in the Spring 2018 Cost Share.

Interactive Map - Look Up Your Address

The EAB Program Tree Map provides residents with information on the Ash Tree treatment plan within Schaumburg. Residents can  see the most recent updates and find out which trees have received insecticide treatment, which were removed or marked for removal, and the areas where new trees were planted.

Dead or Infested Tree Removal

The highest priority is to remove hazardous or potentially hazardous trees from the urban forest. Dead trees will be scheduled according to the order in which they are found, with the most hazardous trees receiving priority and being removed at the earliest possible time. Trees which have a 50% canopy loss will also be scheduled for removal. Due to budget constraints and the enormous task of removing the massive number of predicted dead trees, it may be necessary to defer removals for several months. Privately owned dead trees will need to be removed by the resident. Please refer to the arborist web site to find qualified tree removal contractors.

Ash Trees on Private Property

Village inspectors will make every effort to notify private property owners, including single family homeowners, if there is an ash tree on their property. If you have an ash tree on your property, you will need to plan for its treatment, or in some cases its removal. Once an ash tree is declining the tree should be removed. When hiring a tree removal contractor, it is recommended that you obtain several quotes to ensure that you get the best price. Contractors should be bonded and insured and have a Schaumburg contractor’s license. Please call 311 with any questions about ash trees on your property.

The Village of Schaumburg has negotiated reduced pricing for preventative treatment for Emerald Ash Borer disease.  This pricing is available to residents who wish to treat privately owned ash trees.

Slowing the spread of Emerald Ash Borer

Insecticide treatments are being used by the village to slow the spread of EAB and to save high value ash parkway trees in Schaumburg. Slowing the spread of Emerald Ash Borer to control the mortality rate of parkway ash trees is a very important management tool. Schaumburg is using an insecticide to control the spread of Emerald Ash Borer. The insecticide is injected into the soil at various locations around the base of the tree annually in spring or fall. For larger trees, the insecticide is injected directly into the tree. Managing the Emerald Ash Borer does not mean total elimination of all ash species.

Saving a percentage of parkway ash trees preserves tree value and canopy, as well as all of the other benefits that trees provide the community. The number of trees saved will depend on funding and the health of the trees. Due to the unpredictable nature of the impact on any specific tree, removal may be necessary if treatment is not effective. In other cases, the tree may already be too infested to warrant treatment.
