Reporting your HWA findings helps us manage HWA in New York’s forests by providing locations of local infestations for treatment and allow us to understand where new infestations may end up. For surveying tips and HWA identification information, you can use our Hemlock and HWA ID Guide.
There are three reporting options available for HWA findings listed below. Pick the one method that works for you to report your HWA finding.
1. Use the NYiMapInvasives mobile app:
We encourage you to use NYiMapInvasives to record HWA findings in New York. This invasive species mapping tool is used by NYS DEC to plan management and prioritize HWA treatments in New York. Your contributions to the state invasives map improve our ability to conserve and protect hemlock resources.
To use iMapInvasives, you must set up an account with a username and download the app onto your mobile device. Once you’re signed up, you can use iMap to report locations of any invasive species in New York. For HWA, iMap offers both an HWA option for a positive HWA sighting and an x-HWA option for when no HWA is detected. For more information, visit the iMap website: NYiMapInvasives.org
iMapInvasives also has online tutorials and resources to help you use the iMap mobile app and desktop version. You can check out these helpful tools on the iMap website: https://www.nyimapinvasives.org/online-tutorials
3. Call NYS DEC Forest Pest Information Line:
Phone Number: 1-866-640-0652
2. Send a report to NYSHI
If you do not have an iMapInvasives account, you may report HWA findings using our submission page. Take a picture of the infestation when you are in the field, as we require a photo of the infestation with submission. We ask that you include the address of the finding as well as a detailed description of its location including any useful information such as trail names or major nearby landmarks. GPS coordinates of your finding are especially helpful!
If you are only reporting a single HWA or pine bark adelgid (PBA) finding on an individual tree, you can use our HWA Finding Photo Submission page.
