Thanks for the clarification Daniel.
Cj raises a good point. Coppice with standards makes perfect sense permaculturally and fits nicely into your non-food forest thinking. That way you retain the long term income from the timber trees whilst retaining opportunities for shorter term income generation from the coppice.
Additionally, the growth of the coppice
should help with a) 'forcing' the timber trees to grow straight and b) reduce the amount of snedding required to ensure high quality timber by reducing the amount of branching on the lower stems.
Appologies if these are conclusions you've drawn already! Coppice with standards used to be relatively commonplace in the UK but I'm not sure how widespread it is in other parts of the world.
