Become an Early Detector
How to Become an Early Detector:
  1. View the training webinars below: Learn how to scout for emerald ash borer, Asian longhorned beetle, and thousand cankers disease of walnut.
  2. Choose an area in your community to survey: Search for damage by these pests on trees in your yard, lining the streets in your town, or in public parks.
  3. Fill out a survey report: Even if you don't see damage, please report where you've been searching for these tree killers.

Early detection of new invasive pest infestations is important. It decreases the damage pests cause and can make controlling them easier.


By becoming an early detector of forest pests in Indiana, you increase the chances of detecting new infestations before they destroy your community's trees.

Training Webinars

Learn how to scout for the top three invasive forest pests of concern in Indiana. These recorded training webinars will teach you basics about these pests, types of evidence to look for on trees in your area, and how to report what you find. You will need an internet connection and sound to view these webinars.


  1. Identify a survey area in your community that has trees
  2. Some ideas are:
    • Parks
    • Cemeteries
    • Street trees
    • Neighborhood trees
  3. Identify host trees of EAB, ALB, and/or TCD in the area
  4. Observe host trees closely for symptoms of infestation and record on field reporting form
  5. REPORT what you see, even if there is no damage!


Report results of all surveys, and use a separate reporting form for each area you scout. A printable form is available for use in the field. Please submit reports online. Every report is reviewed by staff at Indiana DNR Entomology and Plant Pathology. Please fill out the form completely, and be sure to include your contact information. Some reports of invasive pest damage will require an official follow-up survey by IN Department of Natural Resources staff.

You can also report invasive species of any type through Indiana DNR's hotline:
