Don, Crown volume versus crown space. I think the crown volume of the crown is made up of both occupied and empty space. To me your terminology seems backwards. If you are looking at trunk volume, you are not subtracting out the volume of the trunk that is hollow because it is enclosed or partially enclosed by the outermost wood. Likewise the hollow space within the crown volume is still part of the crown volume because it is bounded by the outermost reaches of the crown.
I don't think my concept it has any more to do with aesthetics than any other measure of the tree. It is a reasonable measure. You can subdivide it into things like "crown bulk density" in your example, but that is a subdivision of the volume measure, not a better or alternative volume measure. his is because it does not include the entire crown, just those portions filled by leaves. Some people have suggested that tree wood volumes be multiplied by an average density for the wood to create a truer value of the wood present. Ok that is fine, but I see that as a different parameter, a rating of trees by weight, distinct from the volume measure. It does not replace volume of wood as a measure, but is something different. The crown bulk density is a reasonable measure, but is not the same as crown volume.
