The Village will focus chemical efforts against the tree-killing beetle in southern Field Park, the area with the most ash trees in questionable shape.
With $40,000 in the 2012 budget devoted to chemically fighting emerald ash borer—an invasive species of bug deadly to ash trees that has been located in Western Springs—the Village plans to pursue a 10-year strategy combining the treating and removing of parkway ashes. Using a scale from one to six, in which one denotes a perfectly healthy tree and six a dead one, a forester has canvassed the Village’s 1300 roadside ash trees and determined those most likely to require removal this year. That includes seven “five” trees and several dozen “fours.” (A PDF map can be seen to the right.) All seven of the Village’s “five-rated” (nearly dead) ash trees are slated to be removed this spring, along with any others that ail past a certain threshold…

General omnibus bill passes several regular matters; Village President discusses lessons from MMC meeting on emerald ash borer.
Scarcely a Western Springs Board of Trustees meeting has passed in the past few months without citizens stepping forward to weigh in on one of two topics—the Openlands proposal for Timber Trails Unit II and the addition of fluoride to Village water—and Monday night’s voting meeting was no different. No less than seven residents stepped forward, old faces and new, to make their appeals, the topic flipping with each speaker—fluoride, Openlands, fluoride, Openlands, etc.—in a half-hour expansion of Citizen Comments that engulfed nearly two-thirds of the meeting. Openlands proposal supporters speak Speakers entreating the Board to push for the Openlands proposal, which would preserve the western half of the 2004 Timber Trails addition as …

A type of wasp has been found to be effective as an early warning device for Emerald Ash Borer infestation.
Monday, August 8, 2011
The partnership of the Morton Arboretum and Illinois Parks and Recreation Association has discovered a new predator in the fight to stop the Emerald Ash Borer (EAB). Researchers confirmed that Cerceris fumipennis (Cerceris), a native wasp that preys on EAB, was found at Emerson Park in suburban Skokie. Now, researchers hope that the wasp will serve as a sort of “canary in the coal mine,” or an early warning system for EAB infestation, in areas where EAB has not yet been found, said Dr. Frederic Miller, research associate at the arboretum. “By the time humans are able to detect EAB visually, the infestation is usually well-established. We hope this wasp will serve as an effective monitoring tool, giving us an earlier read as EAB makes its …
