Equation

As printed (Cuadro 11 / Resumen)

Ln ( BT ) = -2.0082 + 2.3293 × Ln (dap)

In this library's units, ready to compute (kg)

Aboveground biomass = exp(-2.0082 + 2.3293 * ln(D))

D: Diameter at breast height (1.3 m), cm

Ln is natural log as printed; the Discusión notes that back-transformed log models underestimate but gives no correction factor, so none is applied. Biomass is oven-dry (103 °C) total aboveground (stem + branches + leaves), kg/tree; dap in cm, ht (total height) in m. DBH and height ranges are from Cuadro 2 (descriptive statistics of the sampled trees). Trees from a managed plantation at 2 x 2 m spacing, used to inform urban green areas.
