Jenny, This reminds me of a conversation I had with Theresa Thom of Congaree NP. She mentioned that we at ENTS could measure most aspects of trees. Girth, diameter, height, spread and volume. All above ground. She mentioned that much of a trees mass is below ground. In the roots. I asked her how root mass or root volume may be measured. She mentioned by using ground penetrating radar or possibly sonar. I have seen GPR used to find stuff on programs like The Discovery Channel. However a GPR or GPSonar are beyond ENTS abilities, meaning the finances needed to buy such an instrument. But still, she had a point. To thoroughly measure a tree the roots should be accounted for as well.
It is something to think about.
