Appendix 1: Intercept and slope coefficients (b0
and b1, respectively) of regressions used to predict total,
stem, branch, and leaf biomass (in grams dry weight) of individual mangrove
trees from stem diameter (in mm) 30 cm above the ground (D30).
Equations are applicable to a range of sizes up to seven meters in height.
Equations are of the form Ln(biomass component)=b0 + b1*Ln(D30).
