| description | Using regression models, this research determines the fresh woody biomass for two species of mezquite (Prosopis articulata and P. palmeri) currently used as raw material to make charcoal in Sierra de la Giganta, Baja California Sur, Mexico. This practice began many decades ago, but only since 1990 production data based on issued permissions are available. The independent variables better correlated with the fresh wood weight in a destructive sample were the basal perimeter of the stems for P. articulata (R2 = 0.98, F = 394.12), and the canopy coverage for P. palmeri (R2 = 0.94, F = 63.26). The empirical models employed in these calculations were logarithmic and exponential, respectively. In order to apply these formulas, the appropriate independent variable for each species was used to estimate fresh wood weight in 11 plots of one hectare. 1,283 individuals of P. palmeri and 755 individuals of P. articulata were non-destructively sampled. By employing these calculations, we determined that the biomass useful for charcoal production was 37,040 kg/ha for P. articulata and 2,045 kg/ha for P. palmeri. If each species is harvested exclusively and in accordance with the quantity of wood officially authorized to be gathered during the decade of 1990, these values represent an annual harvest for all the individuals with the adequate size for this purpose (trunk basal diameter > 10 cm) of 179 hectares of P. articulata along riparian areas or 3,928 hectares of P. palmeri on mesas and slopes. |

El presente trabajo se propone definir, mediante modelos de regresión, un procedimiento sencillo de evaluación de la biomasa fresca del leño de dos especies de mezquite (Prosopis articulata y P. palmeri), actualmente aprovechadas como materia prima para elaborar carbón vegetal en la Sierra de La Giganta, Baja California Sur, México. Esta práctica se ha realizado desde hace varias décadas, pero sólo desde 1990 se cuenta con estadísticas basadas en permisos otorgados. Las variables independientes que mejor se correlacionaron con el peso fresco del leño en una muestra destructiva fueron el perímetro basal del tronco en el caso de P. articulata (R2 = 0.98, F = 394.12), y la cobertura del dosel en P. palmeri (R2 = 0.94, F = 63.26), los modelos empíricos empleados fueron el logarítmico y el exponencial, respectivamente. Para aplicar las fórmulas encontradas se procedió a determinar en muestreos no destructivos en 11 superficies de una hectárea el valor de la variable independiente respectiva en 1,283 individuos de P. palmeri y 755 de P. articulata. De esta manera se calculó que el peso de leño en pie útil para la elaboración de carbón para P. articulata es de 37,040 kg/ha y para P. palmeri es de 2,045 kg/ha. De acuerdo con las tasas de extracción autorizadas oficialmente durante la década de 1990, la biomasa del leño calculada correspondería a un aprovechamiento anual de todos los individuos de tallas adecuadas para el propósito (diámetro basal del tronco > 10 cm) de P. articulata en 179 ha en los cauces de arroyos, o bien de 3,928 ha en mesas y lomeríos en el caso de que se hubieran explotado exclusivamente individuos de P. palmeri.
