ANDERSON, Ind. —
An outbreak of emerald ash borers has led the city of Anderson to remove some of its ash trees.
The city released a statement saying several ash trees along the Indian Trail riverwalk have been removed because they were infested with the insects. Anderson public information officer Alisha Cummings said the trees have been replaced with tulip and sycamore trees.
Some other ash trees will be treated with insecticide in an attempt to save them. Cummings said the treatment could be time consuming and expensive.
"The major drawback to treatment is it will be required at a minimum biannually and likely annually," Cummings said in a statement. "It may be difficult down the road to maintain managerial or administration commitment to this long-term endeavor."
Cummings said six trees at Grandview Golf Course were designated for treatment and more could be added if they are decided to be trees of "high importance."
While Anderson makes the call on trees on city property, home owners will have to make the decision on what to do about their ash trees.
The city gave them two options; they can either remove and replace the trees, or opt for the insecticide treatment.
Kaleb Carter, an employee of Roosevelt Carter's Tree Service, said the decision would have to be made on a tree by tree basis.
"We have to come out and look at the extent of the infestation," Carter said. "If it's too far gone we're just wasting money with insecticides."
Carter said every case is different but said shooting insecticides into the tree typically runs from $300 to $600 for each treatment.
For actual removal of the tree, he said there are too many variables to know how much it would cost.
"You've got to look at all kinds of things, how big it is, the shape of the tree, whether it's close to power lines or a house," Carter said. "There's a bunch of mitigating factors that go into removal."
Greg Spencer, golf course superintendent at Grandview, said three types of treatments are available. Treatments for light and moderate infestation are available for purchase; treatments for heavy infestation have to be handled by a licensed applicator.
