Title: Fire Hazard Reduction in Chaparral Using Diverse Treatments

Project Proposal Abstract: High severity wildfires are very common in chaparral. The urban-wildland intermix adds to the complexity of chaparral management because of increased ignitions from people and the potential for high losses of life and property. Prescribed fire has been the most commonly used technique for the reduction in fuel loads in chaparral. The effects of the season of prescribed fire is not understood in chaparral. Burning when soil moistures are high may have a negative impact on obligate seeding species, there is even less information on the effects of mechanical fuel treatments (mastication and chipping). The objective of this study is to contrast the efficacy of prescribed burning with mechanical methods in reducing fire hazard in chaparral. In achieving the primary objective several secondary objectives will be addressed inoluding the effect of the season of treatment on (1) fire hazard reduction, (2) recovery of vegetation, (3) resurgence of fuels, and (4) costs of the different treatments. An experiment is proposed at the Bureau of Land Management Cow Mountain Recreation Area that will use a complete randomize design with replication (4 replicates for prescribed fire treatments including winter, spring, and fall burns, 3 replicates for mechanical treatments including mastication and chipping). Pre-treatment vegetation data will be collected in all units and post-treatthent shrub and herbaceous cover and density will be measured, Technology transfer will occur with a combination of written materials, a world wide web site, short courses, and a self-guiding "drive-walk" route. The University of California Extension services will also be used to disseminate results.
