Emerald Ash Borer


A complete GIS based inventory was completed in 2009. In addition, urban forestry management plans and Emerald Ash Borer (EAB) protocols were developed based on the inventory data. In 2008, the Tree Board identified the need to develop an Emerald Ash Borer Management Plan. The EAB Protocol was developed and approved in 2011.
