"Kill those grape vines."
Wild grapes - A part from those that grow up on my good trees ( which I pull down), I kind of like them... around here they are common but not out of control and are a very good source of food for the turkeys/pheasants I love to hunt. I even try and get them growing on my fencing... I'm even going to try and trellis some into a few little living hedge rows...
The topic of grape vines seems to come up a few time every year on forums. There were quite a few threads about it on that old site.
I can only speak for what I've seen over the last 30 years in the W. Pa, E. Ohio region so I have no idea if grapes may be as troublesome in other regions of the country.
I've watched grapes start out as a slow, limited invasion in the area. At 1st, they didn't seem like a big deal and I actually liked having some around.
Now, they are becoming a major invasive. I remember what it looked like when my hayfields were in the early stages of reverting to brushy cover. I had hundreds of wild crabs, hawthorn and raspberry developing. The areas were quite promising for wildlife habitat.
Then came the grapes. They will climb and smother everything. I see vines with 5 to 6 inch diameters climbing and smothering 100 feet up oak trees. They rob nutrients, moisture and sunlight from surrounding trees. The amount of time and labor that I spend each year trying to save my wild and planted mast trees from slow death by vines is extremely frustrating. I lose valuable, limited time that I could better spend on other habitat projects.
Hinge cutting is another issue when grapes are present. It's difficult, if not impossible to hinge trees that are tangled in vines. It's exhausting sometimes trying to hinge just 1 tree. I accomplish only a fraction of what I could if I wasn't trying to deal with vines.
Another issue with grapes... They make felling larger trees dangerous. Trees hang-up, twist while falling, hinges fail, the vines pull down widow makers, just to name a few hazards that vines pose.
They also climb utility poles and grow across phone and cable wires.
I assume that there is more than 1 species of wild-growing grape. Maybe some varieties, in some climates may never be a problem.
But I'm here to tell you, that the ones growing in this region are the kind of trouble that I wouldn't wish on anyone. And you may have full plans on keeping them contained to certain areas of your property, but that that just isn't possible. Birds will plant them on other properties that you don't own.
If you'd like to see some pics I can post them. Just ask.
