Ed,
A climber with an increment corer can do it. Important work that should be funded. I strongly feel trees grow faster (put on more wood per year) in their "old age". Cambial area greatly increases and even small increments can add up fast. BVP talks about it in his "Forest Giants" book. Misconceptions abound, and ENTS can do great service to educate otherwise. In the face of atmospheric carbon excess a study would be most appropriate. Will F.

I am considering it. The previous notes were just ideas off the top of my head on the subject. The basic premise you are looking at is that tree A over time will change to be the height, girth, and form of tree B over time. (Actually it is the converse of that arguing tree B was the same size, shape and girth as form as A at some point in the past.) On an individual basis that is an unlikely proposition, but as a statistical set of average trees, the arguments would appear to be valid. If you had a big tree that was cut down. And you were able to slice the trunk at various heights. You could determine the the girth at a given point at a given time at a given height by counting backwards from the outermost ring. You could determine at what age the tree reached the height of that cut, and you could reconstruct the form of a particular tree and its volume at any give point in time. The closer the slices together, the more detail you would have and the better you could reconstruct the tree in the past.
