i'd say i'd let people camp on there as long as there was no hassle, i.e. leaving rubbish, chopping green wood and burning things for fun. i'd like to actually invite people out to my woodland and maybe get a "friends of" group established so that the local community has not only a say in the local woodland but an interest, thus we could practice woodland skills there and they would have a nice place to walk their dogs or take their kids/hunt for wilds and feel respect for the woodland and feel responsible for it, even though i own it lol.
it'd be hard to mix shooting with this i reckon, but i'd probably organize occasional vermin culls just notify the locals in advance and signpost the entrances for those days.
actually, on the subject of yobs camping and whatnot, why not setup some camp area's? i.e. brick and mortar fireplaces in slightly open area's at least then when/if the kids romp around on the land it will be contained rather then them dumping all over the shop.
oh and fly tippers will get to stare down the end of a Remington until the police arrive.
