Some of the pictures look like the wild mustang grape vines,

Thank you! Getting a name is very helpful. I don’t know anything about grapevines.

Yes, female plants will fruit but they are as sour as something can be. I’ve heard that jam can be made but I’ve never tasted it.

Oh, I forgot to mention that the leaves taste Ok fresh and can also be used to make chicken or ground meat rolls.

Thanks, all! Great info! And really glad it’s this, instead of Kudzu.

That area is a mess. For whatever reason, the backyard of this rental is fenced only on 3 sides (but not the back, as last pic shows). I’ve spotted Hackberry, Cottonwood, Mimosa, Johnson Grass, ragweed, smilax, pokeweed, and other uwos (unidentified weed objects). There is an old house somewhere on the acreage — I’m guessing the owners decided not to clear the border of their land when this street was built up, for privacy reasons. There’s a very old barbed wire fence in there, too, but vines have nearly toppled it. It is encroaching on our yard, so we keep the bad stuff cut down/dug up on our side. The land owners have Golden Retrievers that sometimes come through and bound around our yard. They crack me up, they’re so cute. And I posted pics before of raccoons that enjoy our birdseed. :D Birds sure do love the cover of it all, too. I’m surprised we haven’t seen any deer yet.

We’ve got Wild Kingdom around this suburban house in town. :)

If it's a native grape species, you won't have to worry about it dying during a drought. Your greater concern would be its aggressive growth habit. If it threatens to take over, just cut it back to suit your taste. Don't worry; pruning it won't hurt it at all. If you can harvest enough ripe fruit, you can make a preserve or wine. That may require bird netting (the birds know when the fruit is edible). As Omar pointed out, you can use the leaves for Greek dolmades or Middle Eastern hashwi.

I have one of the wild varieties that grows in my yard. It grows fairly fast and like someone else said, it’s extremely drought tolerant. I’m able to keep mine under control...it doesn’t grow so fast that it gets out of hand, but it definitely could if no one has kept an eye on it. My neighbors have chickens and I’ve seen them eating the grapes, and I’m sure other birds like them too.
