Forest fuel beds and carbon in Mexico
Forest fuels play an important role in the field of global warming, therefore a proper estimation will allow a decrease of the uncertainty levels of carbon (C) contents. This paper describes the evaluation process for loads of duff (litter and fermentation layer, M) and downed woody material (MLC)....

| description | Forest fuels play an important role in the field of global warming, therefore a proper estimation will allow a decrease of the uncertainty levels of carbon (C) contents. This paper describes the evaluation process for loads of duff (litter and fermentation layer, M) and downed woody material (MLC). A summary of the C content reported in Mexico is also presented. The evaluation of these fuels has been primarily based on the strategy of planar intersections. The contents of C were determined using different percentages of C content with respect to mass (dry weight), ranging from 47.5% to 66.9%, although a percentage of 50% was used, in general. Most works has been focused on temperate ecosystems, where 9.43 Mg C ha-1 of MLC was reported. While for tropical forests there was 8 Mg C ha-1. For M was reported 6.91 Mg C ha-1 and 4.25 Mg C ha-1 in duff, and 5.88 Mg C ha-1 and 1.39 Mg C ha-1 in the fermentation layer for temperate regions and tropical forests, respectively. It is concluded that there is little information on C evaluations regarding M and MLC. In addition, other regions should be considered and standardized evaluation procedures should be used. In this way, the information generated will be comparable and compatible. This will not only reduce levels of uncertainty, but also present information at different scales. |

Los combustibles forestales juegan un papel importante en el ámbito del calentamiento global, por lo que la adecuada estimación de las camas de combustible permitirá disminuir los niveles de incertidumbre de los contenidos de carbono (C) de los ecosistemas forestales. Este trabajo describe los procesos de evaluación de las cargas de mantillo (hojarasca y capa de fermentación, M) y de material leñoso caído (MLC); además, presenta una síntesis de los contenidos de C registrados en México. La evaluación de M y MLC se basó principalmente en la estrategia de intersecciones planares. Los contenidos de C se determinaron usando diferentes porcentajes de contenido de C respecto a la masa (peso seco), que variaron desde 47.5% hasta 66.9% aunque, en general, se consideró 50%. La mayoría de trabajos revisados se enfocaron en ecosistemas de regiones templadas, con registros de 9.43 Mg C ha-1 de MLC, mientras que para selvas se registraron 8 Mg C ha-1. En cuanto a M, se observó 6.91 Mg C ha-1 y 4.25 Mg C ha-1 en la capa de hojarasca y 5.88 Mg C ha-1 y 1.39 Mg C ha-1 en la capa de fermentación para regiones templadas y selvas, respectivamente. Se encontró muy poca información sobre las evaluaciones de C correspondientes a M y MLC, la mayoría enfocada a ecosistemas templados y tropicales, por lo que se resalta la necesidad de considerar otras regiones climáticas. Las evaluaciones de las cargas de los combustibles forestales deben hacerse en forma estandarizada y con protocolos comunes, de tal forma que la información generada pueda ser tanto comparable como compatible. Esto permitirá reducir los niveles de incertidumbre y presentar la información en diferentes escalas. De esta manera, será posible no solo reducir los niveles de incertidumbre, sino también escalar la información.
