Event Types > Community Events


The trees of Portland need us to keep an eye on them and watch for signs of declining health, but how can you know what those signs look like? Join PP&R Urban Forestry staff to learn about the insects, fungi, and other organisms that currently affect or may be a future threat to trees in Portland.
