I don't know what kind of trees these are any help is appreciated
Umatilla County Oregon tree identification
Thank you for the question. Without leaves it's pretty hard to make an accurate identification. There are maple leaves on the ground in one of the pictures. The bark looks like it could be maple, the two on the left are hardwood trees or one tree, the picture on the right not sure of, is it from the same tree? Are these pictures all from one tree? The picture in the middle looks like it could be black locust. The picture on the right might be a pine, such as scots pine.
I would collect some leaves and, with the bark, contact the OSU Extension Office in Pendleton to access a local master gardener who should be able to track it down, call 541-278-5403.
