Detection and Management
Emerald Ash Borer Community Toolbox
To understand the scale of your current or future EAB infestation, including the diversity and health of your urban forest, conduct a tree inventory. Tree inventories could be conducted quickly only for ash trees or more holistically for all trees that your community manages. See the below guides on how to identify EAB and how to conduct a tree inventory.
- EAB Detection Field Guide
The guide provides information on identifying ash trees, various forms of EAB damage and other pests that may look like EAB, but are not. Typically, EAB signs and symptoms do not appear until several years after the infestation. TAKE ACTION NOW.
- How to Conduct a Tree Inventory
An outline of the process of inventorying and cataloging community trees.
- Distinguishing Ash from Other Trees
Helping residents and inexperienced workers determine how to identify ash trees is a logical first step in determining a proper course of action. This resource is from Michigan State University.
- Assessing Your Ash Tree for Emerald Ash Borer

Be sure you make the right ash management choices for your community. We strongly encourage you to consider the benefits of retaining your tree canopy (aesthetics, storm water runoff, increased tourism, increased property value, energy savings, decreased stress, etc.), as well as the financial expense of maintaining the treatments.
- Managing Urban Ash Guidelines
You should read this document first. It will provide Wisconsin communities and professionals that serve them with guidance and recommendations on how to manage their urban forests in the face of emerald ash borer (EAB).
