Ooops
I've just realized whats going on here. Cold, lack of sleep and too much work! I see the problem creating a UV map It is not easy matching the texture to the seams esp with trees without a much time patience and skill. Using ZBrush, blacksmith or some other such program makes it easier but produces UV maps which are all but impossible to change.
My apologies I thought you were saying it could not be textured! silly me!
