The eastern hemlock (Tsuga canadensis) is a hugely important tree species upon which entire ecosystems depend. This species not only creates habitat for countless native plant and animal species, it helps prevent soil erosion, filters runoff, helps regulate the temperature in forests and along waterways, and enhances any outdoor recreation experience. Unfortunately, these majestic trees are under attack from the hemlock woolly adelgid (HWA), an invasive, aphid-like insect.

Slowing the spread of HWA is one of the best ways we can help preserve our hemlock forests. The early detection of emerging infestations is a great way to do this, but we need volunteers like you to help!

Join WNY PRISM's team of community scientists who are helping to survey and map HWA around the region. Getting started is easy!

  1. Sign up to be a community scientist! Remember to request to be added to our Community Scientist Bulletin. You’ll receive email updates on HWA surveys, photos, events and more!

  2. Attend one of our HWA Survey Trainings (usually in January or early February) or check out our HWA Virtual Survey Training to learn how to identify the eastern hemlock and HWA, how to make an iMapInvasives account and download the app to your phone, and important winter hiking safety tips.
  3. You can choose to adopt a location to survey this winter. Please email Rachel Taylor, Community Science and Engagement Program Manager at taylorrm@buffalostate.edu for this year’s list of prioritized areas.
  4. Survey while you hike and make reports using the iMapInvasives app.
