| description | A forest evaluation in relation to dead wood fuel materials quantity and quality in Pinus hartwegii forests was made, in order to show vulnerability conditions and fire propensity. Based on a multispectral satellite images (2010) interpretation, 23,685 ha of P. hartwegii forest in the State of Mexico were grouped in three forest cover classes. A forest inventory, human activity presence, forest fuels and physical parameters measurements were carried out in 30 circular plots of 1,000 m2. Forest fuels quantity and types were assessed following a planar intersect method. Basal area, forest biomass and vertical structure were also measured per site and cover class. The results show differences between the three categories concerning, tree densities coverage (ind ha-1) basal area (m2) and amount of biomass (t ha-1) as well as the vertical structure of forests. Higher quantity of forest fuels occurs in fragmented forests (33.81 t ha-1), of high diameter classes mainly (from 2.5 cm to 7.5 cm, and ≥ 7.5 cm diameter), where fire resides longer in times of a conflagration. Human activities in these areas trigger this situation, a risk that has to be addressed in the area. The application of this methodology could be used in bigger areas of any other forest ecosystem, allowing the determination of the living environment and vulnerability areas, providing useful elements for Integrated Fire Management (IFM) programs. |

En el presente estudio se hace una evaluación forestal asociada a la cantidad y calidad de combustibles muertos en bosques de P. hartwegii para señalar condiciones de vulnerabilidad y propensión a incendios. Con interpretación de imágenes de satélite multiespectrales del 2010, se determinaron tres densidades de cobertura para 23 685 ha de bosque de P. hartwegii del Estado de México. Se realizó un inventario forestal, presencia de actividad humana, carga de combustibles y parámetros físicos en 30 sitios de muestreo de 1000 m2. La estimación de la cantidad y tipo de combustible se realizó bajo la técnica de intersecciones planares. Se calculó el área basal, biomasa forestal y la estructura vertical, por sitio y clase de cobertura. Los resultados señalan que existen diferencias entre las tres categorías relativas a densidad arbórea (ind ha-1) área basal (m2) y cantidad de biomasa (t ha-1) así como de la estructura vertical de los bosques. Se presenta mayor cantidad de combustibles en los bosques fragmentados con 33.81 t ha-1, principalmente de clases diamétricas grandes (de 2.5 cm a 7.5 cm, así como ≥ 7.5 cm de diámetro); donde el fuego reside más tiempo en momentos de una conflagración. Las actividades antrópicas desarrolladas en estas áreas desencadenaron esta situación, que se presenta como un riesgo que debe ser atendido en la zona. La metodología empleada es propicia para el análisis de grandes áreas forestales, permitiendo determinar las características del entorno vivo y del combustible muerto, brindando elementos útiles para declarar áreas vulnerables a incendios en el marco de un Programa de Manejo Integral del Fuego.
