That's a tough question... I guess my initial thought of dunking them in water and measuring the displacement is pretty laughable, eh? Now you'll have me pondering that one throughout the day. In the meantime, I'm curious if it's not practical or if the tree is not accessible to physically collect measurements, is it possible to take scalar photographs of a multi-trunk or buttressed tree at breast height and at multiple angles such that the circumference of each trunk can be sequentially quantified? Multiple angles should allow one to compensate for trunks that are not round, be illustrated graphically, etc. I can imagine such hands-off process being relatively efficient and successful on smooth bark, but not with a highly irregular surface. Lastly, being "old school" (a.k.a., technologically illiterate), I would not be surprised if something similar to this already exists. Any thoughts?..
