The Relationship of Multispectral Satellite Imagery to Immediate Fire Effects
Pages: 64-90
DOI: 10.4996/fireecology.0301064

The Forest Service Remote Sensing Applications Center (RSAC) and the U.S. Geological Survey Earth Resources Observation and Science (EROS) Data Center produce Burned Area Reflectance Classification (BARC) maps for use by Burned Area Emergency Response (BAER) teams in rapid response to wildfires. BAER teams desire maps indicative of fire effects on soils, but green and nonphotosynthetic vegetation and other materials also affect the spectral properties of post-fire imagery.  [Read More]

Post-Fire Burn Severity and Vegetation Response Following Eight Large Wildfires Across the Western United States
Pages: 91-108
DOI: 10.4996/fireecology.0301091

Vegetation response and burn severity were examined following eight large wildfires that burned in 2003 and 2004: two wildfires in California chaparral, two each in dry and moist mixed-conifer forests in Montana, and two in boreal forests in interior Alaska. Our research objectives were: 1) to characterize one year post-fire vegetation recovery relative to initial fire effects on the soil surface that could potentially serve as indicators of vegetation response (and thus, ultimately longerterm post-fire ecosystem recovery), and 2) to use a remotely-sensed indicator of burn severity to describe landscape patterns in fire effects.  [Read More]

Mapping Ground Cover Using Hyperspectral Remote Sensing After the 2003 Simi and Old Wildfires in Southern California
Pages: 109-127
DOI: 10.4996/fireecology.0301109

Wildfire effects on the ground surface are indicative of the potential for post-fire watershed erosion response. Areas with remaining organic ground cover will likely experience less erosion than areas of complete ground cover combustion or exposed mineral soil. The Simi and Old fires burned ~67,000 ha in southern California in 2003. Burn severity indices calculated from pre- and postfire multispectral imagery were differenced (i.e., differenced Normalized Burn Ratio (dNBR)) to highlight fire-induced changes to soil and vegetation.  [Read More]
