On the East Coast, we could use some Wolves, as we're overrun with White Tailed Deer. It's not unusual to see a dozen in my yard, and the road kill numbers are astronomical. Something like 60,000 a year on I-80 alone, and even in Philly proper they're a problem.
Coyotes have driven out a lot of the foxes, but I'm not so sure wolves are the solution for that.
