The Emerald Ash Borer was confirmed in Forsythia Crossing Park early in the summer of 2015.  This invasive species has probably been damaging the ash trees in the township for a couple of years.

The adult EAB lays eggs on an ash tree in late spring-early summer.  The eggs hatch and bore through the bark and into the cambium of the tree.  The larvae feed and live in the cambium until they emerge the next spring/summer as adults to start the cycle over again.  The cambium is the active growing portion of the tree between the bark and the wood.  The larvae damage the cambium and prevent the tree from getting the water and nutrients it needs to stay alive.  The tree begins to die back at the top and most often dies completely after three to five years.

Do you have an ash tree in your yard?


If you do have an ash tree that is still healthy looking you may want to have it evaluated by a certified arborist.  There are treatments available that may save trees that have not yet been seriously damaged from the Emerald Ash Borer.
