Can anyone help identify this tree? I think it is a weed tree, but only guessing this because of its preponderance at the flanks of a highway overpass and the visual yuck factor. Its bark is yellow-green -no leaves just yet. The largest one I saw was about 15 feet tall.

If its a weed, the next time we are moving a trail, I can suggest that we don't need to replant them, as had been the case on our last outing. As it turns out, expertise in native and non-native plants its pretty useful on trail projects.
