Hello, sorry to miss this report as it was filed under the Plants section. For suspected EAB, please report it under the Insects section. At first glance, it is impossible to tell from the photos what type of damage is on the ash trees. Oregon ash can show symptoms of decline and branch mortality from a number of insects, diseases and environmental issues. Below are some links to help identify EAB from other causal agents. Thank you for your report!
