In May of last year, the Mokena Village Board launched an aggressive program to proactively deal with the Emerald Ash Borer (EAB), a highly destructive insect attacking ash trees throughout the Mokena community. The program involves the treatment or removal of almost 3,700 public/parkway ash trees over the next several years.
Emerald Ash Borer (EAB)
Following are key elements of the program, which is based on a community-wide tree inventory and EAB management plan (see links below) developed by Graf Tree Care, Inc., a professional arborist consulting firm retained by the Board:
* Just under 300 of Mokena’s healthiest parkway trees are being treated annually over the next 6 years to preserve a representative ash tree population in the community.
* Almost 900 parkway ash trees will be removed this year and in each of the next 2 years (multi-year phased removal of all untreated ash trees). Residents having applied treatment to a parkway tree (personally or through a qualified contractor) are encouraged to fill out and return an "EAB treatment form" (see link below) to the Village at their earliest possible convenience to avoid the potential for future removal.
* Those trees most severely infested with EAB are being removed first, based on the tree inventory and EAB management plan. Unfortunately, due to the significant number of trees (over 3,400) that will ultimately have to be removed, not all parkway trees appearing to be in poor condition or in failing health will be able to be removed each year.
* For parkway trees removed over the next 3 years, replacement parkway trees will be planted in their place within a year of their removal. Replacement trees will meet the Village’s standard specifications (2.5” caliper) for parkway trees, with appropriate species selected for each specific planting site by Mokena’s consulting arborist based on lighting, soil conditions, tree diversification goals, and other factors.
* There will be no cost to residents for Village-initiated treatment, removal, or replacement of any ash trees located in a public parkway adjacent to their property.
* As in the past, all responsibility for the maintenance, treatment (if desired), removal, and replacement of ash trees located on private lots will rest with individual residents/property owners.

EAB Management Plan (Updated November, 2013)
Because EAB is a community-wide issue impacting (directly or indirectly) everyone that lives in Mokena, the Board has set aside $1.69 million to fund this multi-year program. Monies for the program are coming from cash reserves generated through operating efficiencies and rising sales tax receipts generated by local businesses.
