Rather than build a trail, and then hope that people don’t use it, is it not better to not build a trail in an area that gets in such a state in the first place?
You can be selective where you ride, which I would say most of the locals do, we all know the bad places and generally avoid them. But that said almost none of the trails in cranham are “legal” for bikes to use anyway, so I think common sense is the best bet!
