just a thought about the covenant on woodlands.co.uk it says "No Commercial campsite" and "no business from the land apart from forestry" .
would you be able to set up a bushcraft school?
as you are not allowing people to camp there when they want and you are not refining the materials and resources of the land directly for commercial gain i.e keeping livestock in it,
you are teaching people how to work with the forest, maybe you could put a conservation spin on it.
