摘要

Fire risk is an ever present management dilemma in many urban interface regions of the west. As options for mitigating this risk are considered, a number of concerns need to be addressed in order to carefully select the most appropriate treatment option. A study investigating effects of understory shrub mastication was implemented at Whiskeytown National Recreation Area with support from the Joint Fire Sciences Program. This study evaluated the response of vegetation, fire behavior and soil resources, to six different fuels treatments. As demonstrated by this study, hazardous fuels treatments do have ecological effects that need to be considered in setting management objectives. Specifically, findings from this study highlight significant differences between treatments, including the following: In sites where understory vegetation is masticated and left on site, fire behavior indices actually increased in comparison to unmasticated fuelbeds under the tested parameters. Low intensity spring burns can be used to reduce surface fuel loading in masticated fuels, but mortality to residual vegetation may be high.
