Table 2 Regression coefficients for biomass of foliage, bark, living wood, dead wood, and total aboveground live biomass (AGLB) for Corylus cornuta ssp. californica in the form ln(biomass) = A + B × ln(diameter), where ln is the natural logarithm, and diameter is either basal diameter (DBA) or diameter at breast height (DBH) in cm. SEE = standard error of the regression in arithmetic units. CF = correction factor for A (see Methods). Regression coefficients for age are linear; Age = A + B × (diameter). All relationships P < 0.001.
