Table 1:  Regressions used to predict total, stem, branch, leaf, and proproot biomass (grams) of individual mangrove trees from structural measurements.  Equations are applicable to a range of sizes up to seven meters in height. Independent variables:        D = diameter (in cm) at 30 cm; H = total height (in cm); CRWNV = crown width * crown length * crown depth (each in cm).
