| Los incendios forestales, además de afectar la calidad del aire y la cubierta vegetal, provocan cambios importantes en las propiedades hidrológicas del suelo, aceleran el proceso de erosión y contaminan por sedimentación. Sin embargo, en México, la información relacionada con los incendios esta más enfocada a estudiar y documentar el impacto ambiental sobre la calidad del aire y la cubierta vegetal, sin ahondar en los efectos sobre el suelo , el escurrimiento superficial y la producción de sedimentos. Por tal motivo, el objetivo de este trabajo fue evaluar la severidad de la quema sobre la infiltración del agua, la producción de escurrimiento superficial y sedimentos. Se evaluaron doce tratamientos derivados de las cuatro severidades de quema... |

| There are varying definitions of old-growth forests because of differences in environment and differing fire influence across the Intermountain West. Two general types of forests reflect the role of fire: 1) forests shaped by natural changes in structure and species makeup—plant succession—that are driven by competitive differences among species and individual trees and by small-scale disturbances, and 2) forests where plant succession processes are disrupted by major biological disturbances (fire, insects, wind, or drought) extending across larger areas. Some case examples of old-growth forests where fire was historically frequent are used. The examples sketch out the typical biophysical settings, fire regime, natural disturbance... |
