Biomasa arbustiva, herbácea y en el piso forestal como factor de riesgo de incendios

Abstract

El presente estudio destaca la importancia de generar información de los combustibles forestales para determinar el riesgo de incendio en bosques de pino, de encino y mesófilo de montaña en San Antonio, Chimalapa, Oaxaca. Su objetivo consistió en calcular el contenido de biomasa aérea en los diferentes componentes encontrados en el piso forestal de tres tipos de vegetación, bajo índice de riesgo de incendio. Durante 2014, se establecieron de manera dirigida 15 sitios de 1 000 m2, y subsitios de 9 y 1 m2 para evaluar los compartimentos de madera, hojarasca, necromasa, arbusto y herbácea; se determinaron índices de riesgo por tipo de vegetación. La información se validó mediante análisis de varianza y pruebas de medias (Duncan, 0.05), bajo un diseño completamente aleatorizado. Los contenidos de biomasa en el piso forestal fueron de 8.77 t ha-1 para el bosque mesófilo de montaña, de 15.23 t ha-1 para bosque de encino y de 1.07 t ha-1 para bosque de pino. La biomasa contenida en herbáceas fue superior (p = 0.009) en el pinar, en comparación con los otros tipos de vegetación; sin embargo, al ponderar la carga total de combustible en el piso forestal, resultó entre 2.0 y 2.59 t ha-1, lo cual indica que el índice de riesgo de incendio forestal en el área de estudio es bajo; en el bosque mesófilo de montaña se registró el valor más alto.
