When I see one that hairy and large, I think of poison ivy.

Neither Grape nor Wisteria have aerial roots. So, Poison Ivy or, possibly, Ivy (Hedera). But I don't think it's Hedera. Did it have evergreen leaves or was it bare? If bare it's not Hedera. If you could photograph the surrounding leaf litter we could probably id it from dead leaves.

My bet's on Poison Ivy.

I don't ever recall seeing any leaf litter on this vine. I cut the base awhile ago so nothing to ID other than the vine itself. I have a lot of poison ivy vines about (all hairy), along with Muscadine but Muscadine has strings hanging off of it. This one is definitely different then the others. goes up 30 feet or more.

i had PI like that on my lot when i moved in ... took me about 3 years to kill it ...

because the underground root ... or stem ... was just as big.. and probably a mile long ...

i would cut it to ground level .... and treat it will killer ...and then spend 3 years spraying all the ones that pop up ;... about 3 times per year ...

and i would get a ladder.. and cut the hanging one to about 6 feet ...

AND JUST LEAVE THE REST HANGING IN THE TREE ... there is no need to pull it down ... it will eventually lose its toxicity ... and rot apart and fall down

and DO NOT BURN THE CUTTINGS ...

Leaf litter isn't on the plant. It's the dead leaves lying around on the ground. Any 'strings' on Muscadines would be bark strips. It doesn't have aerial roots.

I'll see if I can find a shot of the Muscadine strings I'm talking about. Any leaf litter on the ground or elsewhere would be gone by now. I'm also going to peer waaay up into that tree with binoculars to see if I can find any other form of identification. The exterior is smooth unlike the other poison ivy vines in the area. Nasty stuff! I've had 3 bouts of it this year.

you will know in spring.. when it leafs out from the bottom cut ... it will not die for being cut ...

I can see plenty of leaf litter in the photo. Where has it gone since you took it?

I can't remember exactly when I cut this vine but it was long before this fall. I live on a heavily wooded lot so what I believe you are seeing are from other trees. This particular vine is on a pine tree so you see pine needles at the base.

It could be a Campsis radicans vine.

agree with nel. looks exactly like trumpet creeper, campsis radicans. have never seen Virginia creeper make a vine/trunk like that.

Virginia creeper can make a trunk like that, and when its older, there are adventitious roots like that without the suckers visible on younger vines, so it is a possibility. It looks more like Campsis radicans than poison ivy to me since IME there are usually more adventitious roots on PI to the point that they look furry.

However, probably the best way to ID for sure is to wait until spring and see what leaves come up nearby since usually a cut vine like this will resprout from roots in the soil for all 3 species suggested (unless the cut stump was painted with herbicide.)
