Insects like the Emerald Ash Borer are causing major problems across Northern Illinois. (see attached video)
"They won't eat anything else except an ash tree."
That's why the Forestry Division of Rockford will be removing nearly seven-thousand trees in the Forest City.
"I assume the city is being proactive realizing that their going to die. They're starting to take them down now so that they're not inundated with work all at one time when they die," said John Moors, Director of Collections at Klehm Arboretum.
Moors says these destructive little insects traveled a long way before getting to the stateline
"It's an Asian insect that was first discovered in Michigan. They feel that it came in some shipping containers or something like that. And, they lost hundreds of millions of trees in Michigan and its worked its way along interstates to this area."
Moors says there's a way to distinguish trees affected by the Emerald Ash Borer from healthy trees.
"You'll notice dead branches on the upper third of the tree. And that's where it starts."
And, if you have an Ash tree this is how you can find out if its been affected by the insect.
First look for D-shaped exit holes in the branches and you can also then look underneath the bark which is a little difficult to do. You have to peel of the bark to do it.
