But they are not controlling their numbers by hunting them. There was "no measurable impact" to the number of foxes during the one year ban on fox hunting in 2001 during the FMD outbreak. The International Weekly Journal of Science derived from this that there would be no change to the fox population if fox hunting was banned completely.
Fox hunting was never about controlling national numbers of foxes.
It was a service afforded to those who needed it most. If there had never been a demand, there would have been no hunts in existence.
How could the International Weekly Journal of Science come to that conclusion after a few months of respite for the fox population? That's about the most unscientific statement I've ever seen.

Did they take into account the excellent records kept by hunts?
Probably not..........after all you can't trust barbarians, can you?
One of the most important aspects of fox hunting with hounds was that it was a method of selectively culling foxes and was a practical way to maintain a healthy fox population.
On occasions when farmers and the like had problems with particular foxes doing damage to their livelihood, the hunt was able to do something about it by laying hounds onto the scent of the offending fox, likely in the early morning when scent was good, quite often resulting in the death of the offender before the antis were even out of their pits.
The remaining legal methods of killing foxes are by their very nature unselective and indescriminatory.
No doubt those who do not understand will bring about legislation to stop those too, but foxes will always be killed by those who wish to do it, and by any means which works.
Far better to have a humane and visible method than an underground movement, don't you think?
