The log that makes it to the mill is what those stats are about. Not the tree as a whole. I live in BC and a huge portion of the tree is left in the forest. All of the branches, smaller trees, tops and other bits not worth transporting are burned in slash piles or left in the forest to decompose. There is typically at least a foot thick layer of wood debris left in the cut block after the logging companies come through. Some forestry companies near me allow firewood processors to come through and grab the leftovers out of the clear cuts, but it is pretty close to a rounding error.
