We also have buckthorn here in Idaho in the northwestern U.S.A. It is arid in the southern part of this state, where only a few species of trees are native. A quick search online tells me we have multiple native genera in the family Rhamnaceae. Your buckthorn photo looks like plants I see here. I am glad to know more about them. I look forward to this series!
