I'm surprised they didn't count the root system as well, those are usually gargantuan for the trees I see raised for lumber. Going by volume is also remarkably useless because if a tree produces some large non-dense structure like a leaf it skews the numbers. The issue with industrial forestry isn't waste, but monocropping and habitat destruction.
