A look down streets in most cities and a walk through the woods will reveal the prevalence of our native ash trees.
These trees are at risk. A small dark metallic green insect, the Emerald Ash borer, has destroyed millions of trees in the United State and Canada.
The larval stage of this insect feeds under the bark, eventually causing the tree's canopy to thin and dieback. The symptoms may take several years to appear.
A close look at the trunk will reveal the characteristic 1/8" D shaped exit hole in the bark.
So what can you do? Monitor the health of your trees and watch for signs of this pest. Several preventative treatments are now available.
And if you suspect Emerald Ash borer is present contact your local extension service or the nearest Department of Agriculture or Natural Resources.
And most importantly don't transport firewood out of your community.
