Description of specimen

Oregon Ash tree in sudden decline this year, mostly bare, leaves very small. Photo attached. Unable to examine its trunk due to surrounding blackberries. Signed up for CSWCD class June 6.

Commentary

You aren't close to any known infestation. Canopy decline is an indicator that something is wrong, but we need to see some signs of damage. Stay on the lookout for beetles in the summer.

I'll be at the CWSCD workshop on June 6th. We can talk about your tree and help you learn how to identify an EAB infestation. Until then you can learn more at OregonEAB.com. The Identification tab under Resources shows you what to look for.
