Here's tree-of-heaven www.invasivespeciesinfo.gov/plants/treeheaven.shtml - certainly it would be expected in Nolde Forest. I'm not sure the picture is it. The video linked in turn from the page I'm linking in this post may help (despite its cheesy intro).
I can't honestly recall encountering Devil's Walking Stick in PA, other than in Martin Hill Wild Area where I've literally run into it many times. The former 45%+ gradient northern descent from MST's summit required grabbing onto it, until the trail was relocated onto a gentler (still steep) vector.
Now I remember the blue berry - It's "Mile-a-minute" vine - an encroaching invasive particularly fond of open fields. It literally pulls down native species. There is a lot of it around Emmitsburg water shed.
We went on vacation once and returned to find mile-a-minute totally choking a flower bed that had seemed completely clear when we left. Definitely need gloves and long sleeves for pulling it out. Fortunately it hasn't seemed to have found its way to where I go in northern PA yet.
