Fox numbers will actually fall, following the Ban.

I have seen a lot of pro hunters claiming that if we banned Fox Hunting here, Fox numbers would multiply at an alarming rate. Unfortunately for them though, the evidence simply does not back up that theory.

It's worth pointing out that, since the Ban on Fox Hunting in the rest of the UK, more than 20 years ago, urban Fox numbers in the UK have actually fallen, by as much as 50% in some areas.
