Treat the Ash Trees!

April 17, 2012

Large Ash Tree Barret Hill

The Emerald Ash Borer is an exotic, metallic-green colored beetle that has killed 50 to 100 million ash trees in the United States since 2002. In the past decade, it has become one of the most destructive non-native insects found in the U.S. The beetle damages ash trees by feeding on the inner bark, disrupting the tree’s ability to transport water and nutrients. Once trees are infested with this invasive species most will die within two years.

To help combat the infestation, Olmsted Parks Conservancy applied and received a $10,000 grant from the Kentucky Division of Forestry. The Conservancy is working closely with Metro Parks to treat 100 ash trees throughout the Frederick Law Olmsted Parks.There are approximately 1000 more trees we need to treat at a cost of $96 per tree. Please consider making a donation(click here) to save the canopy of Ash trees and help our community.  Your donation will help save the Ash trees in the Olmsted Parks.

What can you do to help stop the Emerald Ash Borer? Check your own yard for Ash trees. Call a tree care service to advise you on whether or not your trees should be treated to combat this dreadful bug. If all homeowners treat trees to prevent infestation or remove infested trees, the borer will eventually die out.  Here is a link for more information http://pest.ca.uky.edu/EXT/EAB/welcome.html

Here is an example from Toledo Ohio of a street that was hit by the Emerald Ash Borer:

Ash tree lined street before borer attack.

Three years later, same street, all trees are dead.

Below shows the process for treating Ash trees with the IV system.

Insertion of injection needle into the arbor plug. Treatment chemical is pulled from the container through the plastic tubes and into the tree.
