Here, it's the coyotes that are the problem. I see very few foxes, but I sure see a lot of coyotes. Hell, I had five of them yipping at me, when I was hanging laundry in my back yard. They have basically no fear of humans here, and are more than happy to kill peoples' pets. I find it hard to believe that an animal that is NOT native to New York would not have a detrimental effect on the ecosystem. After all, they didn't migrate here until the 1930's. That clearly makes them a non native species. Any other non native species, we'd be trying to wipe out.
