I wouldn't say it wasn't useful for anything, but it is a major nuisance and aggravation much of the time. The cattle do graze the tender new growth and will browze it when dry summer heat make lush grass scarce. Certainly the berries are wildlife food and a major means of its dispersal. It's also a safe haven cover for lots of animals - rabbits, fox, copperheads and rattlesnakes and less unpleasant snakes. I've seen birds nesting in it and taking active cover when a raptor flies over. But when it's growing where you don't want it, it's extremely hard to eradicate. I guess the argument could be made that it makes a nice living fence when it takes over a fence line while providing cover for wildlife, but it also makes a fence really hard to repair. Most of the time, I'd prefer a lot less than grows around here
