Although the guys who built the trails didn't know it was protected land, it should still be their responsibility to find somewhere else (not Natural Englands) because at the end of the day they are protected for a reason. Those of you who (rightly) say we bikers love the countryside should understand the passion that Natural England have. Its not up to the them to come to us to give us somewhere to build, we should be the proactive ones going out and talking to land owners so we can get our own trials without fear of them coming along later and having a moan.
