Reporting a Tree Disease

Think you found a Tree Disease?

The sooner we find new infestations, the better our chances of slowing its spread to other trees nearby or to other areas, and of eradicating it where it has been detected.

  1. Check out the gallery of invader pages to confirm the species that you think you have found.
  2. Then submit your photos below. If possible, please include the whole tree, bark, and branching/leaf pattern.
