INDIAN HEAD PARK – Indian Head Park plans to spend about $5,100 combating the spread of the emerald ash borer.
The village arborist evaluated the trees on public property in the village and identified eight ash trees that should be removed because they are already infected with the ash borer. The trees are on Glenbrook Lane, Glenbrook Lane West, Arrowhead Trail, Blackhawk Trail and Sequoya Lane.
The cost to remove and replace most of the trees with a different species was estimated to cost $450 each, or $3,600 total.
The arborist, Bill McConaughy, recommends 19 ash be injected with a pesticide every other spring. The village public works employees will do the treatment, at a cost of about $63 each, or $1,197.
Trees that are less than 10 inches in diameter can be treated annually with an in-ground pesticide for $6 each. The arborist identified 51 ash for this treatment, for a total of $306.
McConaughy reported the insecticides have about an 80 percent success rate.
“We’ll see if this works,” Indian Head Park Village Administrator Frank Alonzo said. “If the trees survive, we’ll keep our trees. I think it’s worth a try.”
The arborist also said nine other ash trees in the southeast corner of Blackhawk Park should be removed.
