Estimating Weights of Branch Segments

Estimating the forces and loads applied in tree systems requires the weight of different parts and portions be determined. One of the most difficult measures to estimate is green xylem weight in branches. Wood weight can be precisely and accurately determined in the laboratory from small samples at oven-dry moisture contents. Within living trees, moisture content values are difficult to determine accurately. The moisture contents of living tree xylem and associated tissue can vary between 30% and 250% as compared with the weight of any associatedwoody material.
