I'm sure someone far more qualified than I could give a better answer. But from what I've read a wood is excellent for renewable fuel, building materials, food [mushrooms, nuts etc], flowers [for your bees]. I've heard woodland described as 'the most efficient way to collect solar power' i.e. in the form of fuel I suppose. I think if you coppice your trees then you can yield a lot of wood for burning, charcoal, making things etc. As well as being ecologically very supportive to the air, insects and animals. And a pleasant environment to be in of course...
