| description | The implicit prediction is an important tool to know the type of products that can be obtained from the forest in a given time, and thus to plan the sustainable forest management. In the Sierra Norte de Oaxaca, Mexico, there are even-aged stands of Pinus patula, a fast-growing timber species with economic and ecological value. The aim of this study was to estimate the growth and yield timber of this species with the diameter distribution models approach. The database consisted of 132 diameter distributions from 66 permanent sampling plots of 400 m2, located in Ixtlán de Juárez, Oaxaca, Mexico. Stand diameter distribution was estimated through Weibull function with parameters prediction and percentile prediction approaches. Also, minimum diameter and quadratic mean diameter projection models were fitted to recover the parameters and to estimate the diameter structure of stands on the future. The best system was the prediction of parameters because of this had the smaller bias in the prediction of the total volume with respect to an explicit projection system designed for the species. Therefore, it is recommended to use this implicit prediction system to plan the management of even-aged stands of P. patula. |

La predicción implícita es una herramienta valiosa para conocer el tipo de productos que se pueden obtener del bosque en un tiempo determinado y, de esta forma, planificar el manejo forestal sostenible. En la Sierra Norte de Oaxaca, México, existen rodales coetáneos de Pinus patula, una especie maderable de rápido crecimiento e importancia económica y ecológica. El objetivo de este estudio fue estimar el crecimiento y rendimiento maderable de esta especie a través de dos sistemas de predicción con el enfoque de modelos de distribución en clases diamétricas. La base de datos consistió en 132 distribuciones diamétricas, provenientes de 66 sitios permanentes de muestreo de 400 m2 localizados en Ixtlán de Juárez, Oaxaca, México. La distribución diamétrica del rodal se estimó mediante la función de densidad de probabilidades Weibull con los métodos de predicción de parámetros y predicción de percentiles. Asimismo, se ajustaron modelos de proyección del diámetro mínimo y diámetro medio cuadrático del rodal para recuperar los parámetros y estimar la estructura diamétrica de rodales a medida que cambia la edad. El mejor método fue el de predicción de parámetros, debido al sesgo menor en la predicción del volumen total con respecto a un sistema de proyección explícito diseñado para la especie. Por tanto, es preferente el uso de este sistema de predicción implícita para planificar el manejo de los rodales coetáneos de P. patula.
