Thanks to everyone that has taken the time to respond , although I'm slightly disappointed there wasn't the "feed the tree hugging communist lentil eater a pork pie" from you know who
In fairness there are some good ideas and many along the lines of what we were thinking ourselves.
There's no planning permission on this land but my friend is cynical when he looks at the current approach to green belt.
Difinately no go cart track though I think the site would be almost ideal but he does want something more peaceful.
Alotments would be good but at a little under 20 miles outside of the nearest large town (Welshpool) perhaps too far away?
The two options he does like are the eco campsite and the animal resuce center. The first would involve a certain amount of investments to lay in toilets and infastructure and he has looked at those yert type of tents and aim up market.
The animal center would need funding so would involve setting up a charity but a bigger stumbling block pointed out by his brother, also a vegetarian , is that he's never kept animals in his life (apart from goldfish) let alone sick or abused ones.
As I said the land is currently leased for grazing but from what he can make out the current owner doesn't seem to make that much from it. I'll admit I don't know what aid is available to pasture land in the way it is to arable land. The idea to grow cannabis isn't a million miles away as hemp can be grown on set aside I believe although it's not narcotic but used in the paper trade.
The tree planting is also another good idea worthy of futher research. Grants, plus once planted relatively little to do maintenance wise and very little chance of rustling. I did suggest along the same lines to burn wood to make charcoal. Not the cheap crap that's a hard as brick and found on garage forecourts but better quality soft stuff used by artists and thus more expensive.
The idea about turning it into a garden center type of thing would be good but sooey I think it was did say "if he's young enough". My friend is in his early fifties so not sure about that. On a similiar vein I suggested using it as an area for gardeners both pros and not to diposit their waste which could then be rotted down , bagged and sold as fertilizer but he wasn't too keen on that one.
