In a past life (i.e. when I was young) I used to get permission to go onto the MOD land and clear up the mess that was left behind when they had cut down trees. It was mainly pine species and it was difficult work because it was all heaped like a pile of 6" pick-up-sticks (you know, that game where you have to pick up the sticks without the others moving). The problem now is that I would need three copies of a risk assessment, public liability insurance and full chain-saw tickets. People like the Forestry just can't get away with letting people go and use 'tools' on their land; they'd be liable.
