I am not good at identifying trees, most of what is in my yard is invasive and I'm trying to see if there is anything worth saving. I think the trees are some type of dogwood, based on leaves, however I know there are a few similar invasives. I think the pink part and dark berries will help with identifying for someone with more knowledge.
Also, this very invasive plant with red thorny vines and kind of a white coating over, if that makes sense, and broad leaves. Hopefully the pictures will help. I took these in the fall. Thanks! I realized I can only post one picture, so will start a new one for the vine.
