Title: Age-Class Mosaics and Wind-Driven Fire: Further Fuel for the Debate

Project Proposal Abstract: Recently revised southern California national forest management plans identify virtually every acre as the wildland-urban interface (WUI) environment, because any fire start could burn into human development within one burning period. Continuing debate about the role of chaparral age class mosaics in modifying fire size and behavior under wind-driven conditions confounds managers' ability to implement prescribed burns in remote areas to protect WUI - opponents fear that inevitable large fires will reburn young fuels, leading to chaparral regeneration failure and type-conversion to weedy grassland. The Santa Ana wind-driven Esperanza fire (2006) burned through the North Mountain Experimental Area (NMEA) and vicinity, including 10 previous fires. Multiple images of the fire's progression were taken using Riverside Fire Lab's airborne FireMapper thermal-imaging system. Existing fuels data and historic NMEA maps plus new fire images provide a unique opportunity to investigate relationships between vegetation history and fire behavior and severity. We will coordinate with an existing JFSP shrub fuels project (03-1-3-06) as well as generate our own estimates of fuel consumption and fire behavior to ground-truth temperature data from FireMapper. Soil samples collected in a stratified random manner will be used to assess seed bank survival, evaluating the utility of FireMapper images for severity mapping. Coordinated documentation of vegetation recovery will address the effects of age class and fire behavior on chaparral regeneration and nonnative species invasion. This project will extend lessons learned from 2003 large fires (JFSP 04-1-2-01) to address the chaparral mosaic debate and will enhance utility of an existing tool, FireMapper.
