| description | In this work physical properties relevant in estimations of fire behavior and the forest fuels dynamics in an oak forest in the Estado de Mexico, Mexico were analyzed and evaluated. The evaluation was conducted along the forest fires season. It was estimated: i) the basic density and moisture content of woody fuels by time lag; ii) the forest fuel load in three ways; and iii) the forest fuels dynamics. The basic densities of the woody fuels in the study site followed a decreasing tendency: 1h = 0.585 g cm-3, 10 h = 0.478 g cm-3, and 100 h = 0.412 g cm-3. The woody fuel load estimated with basic densities from the collected material was the lowest: 11.6% less than the value obtained using conifer basic densities, and 43% less than using the basic density of oaks from bibliography. The incorporation rate of fuels was equal to 40.532 Mg ha-1, along the fire season, with 62.9% (25.491 Mg ha-1) for leaf litter, and 18.8% (7.603 Mg ha-1) for woody fuels. The decomposition rate (k) during the fire season was of 0.0827 for leaf litter, and for woody fuels 0.0861 for 1 h time lag, and 0.0404 for 10 h time lag. Biomass load added to the forest floor at the end of the season increased to an accumulated load of 205% for 1 h and 10 h time lag for branches, while for the leaf litter was 58.7%. |

Se evaluaron y analizaron propiedades físicas de combustibles forestales de importancia en la estimación del comportamiento del fuego y la dinámica de los combustibles durante la temporada de incendios forestales en un encinar del Edo. de México. Se estimó: i) densidad básica y humedad de los combustibles por tiempo de retardo (TR); ii) carga de combustibles leñosos por tres variantes de método; y iii) dinámica de combustibles forestales. Las densidades básicas de los materiales leñosos decrecieron a mayores tiempos de retardo: 1 h = 0.585 g cm-3, 10 h = 0.478 g cm-3 y 100 h = 0.412 g cm-3. La carga de los combustibles leñosos, estimada con densidades básicas de los materiales recolectados, fue la menor: 11.6% menos con respecto al valor obtenido usando densidades básicas de coníferas y 43% menos al usar la densidad básica de encinos referida en la bibliografía. La incorporación de materiales fue de 40.532 Mg ha-1 durante la temporada de incendios; para hojarasca correspondió 62.9% (25.491 Mg ha-1) y para leñas 18.8% (7.603 Mg ha-1). La tasa de descomposición en hojarasca fue 0.0827 y en leñas 0.0861 y 0.0404, para 1 h y 10 h TR, respectivamente. La carga acumulada al final de la temporada incrementó 205% en ramillas de 1 h y 10 h TR, mientras que la hojarasca lo hizo en 58.7%.
