Okay. Got me. I went by the larger leaves in the first 2 pictures of your 7:26 pm posting. Those, front and center, look like individual leaves - and strongly resemble wild grape. I even thought I saw a tendril or two.
The 3-leaflet leaves in the background look very much like poison ivy to me.
Please note, this is going by the latest pictures you've posted. And some wild grapes, cat grape to name one, have 2 deep lobes that maybe could morph into leaflets? The Book says cat grape has hairless leaves that are usually deeply lobed. Cat Grape has 3/16" thick woody pith partitions and tendrils. In fact, if there are any tendrils, check the pith. It's either a wild grape of some sort or an ampelopsis.
The same comment could concievably go for ampelopsis? In fact, the Book says that Ampelopsis brevipedunculata has alternate leaves, simple, that are more or less 3-lobed and coarsely toothed; tendrils may be scarce or lacking. Here the pith is white.
For Poison Ivy, the end leaflet has a longer stalk than the 2 side leaflets; all 3 leaflets have pinted tips. Buds are visible, hairy and stalked. And does not have any tendrils. Poison Oak has blunt-tipped leaves that may be lobed. My plant professor claimed that there was little difference taxonimically between poison ivy and poison oak.
Does this help you with identification?
