Table 1 Allometric equations used for computing shrub biomass in the Yosemite Forest Dynamics Plot, with all equations in the form ln(biomass) = A + B × ln(DBA), where DBA is basal diameter and ln is the natural logarithm. The number of shrub demography plots for each species (used to generate biomass figures from patch areas) is indicated by n.
