Report HWA Finding

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.
