Indiana town to destroy 15,000 trees

ashThe town of Decatur, Indiana has decided to cut down 15,000 ash trees in order to slow the spread of the emerald ash borer infestation.

The Associated Press is reporting that the estimated $1 million operation is necessary to eradicate a pocket of the insects that have appeared outside of their natural spread area – likely brought in by transported firewood. The larvae of the insects have already been estimated to have destroyed 8 to 10 million trees – mainly in Michigan, but increasingly in Indiana and Ohio.

If left unchecked, the emerald ash borer could cause the extinction of the ash tree as a species in North America.

To help stop the spread of this insect, Indiana Michigan and Ohio have created a joint website to disseminate more information about the threat at:
