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]

Fire Metrology: Current and Future Directions in Physics-Based Measurements
Pages: 13-35
DOI: 10.4996/fireecology.0601013

The robust evaluation of fire impacts on the biota, soil, and atmosphere requires measurement and analysis methods that can characterize combustion processes across a range of temporal and spatial scales. Numerous challenges are apparent in the literature. These challenges have led to novel research to quantify the 1) structure and heterogeneity of the pre-fire vegetation; 2) energy released during the combustion process and the ultimate disposition of that energy through conduction, radiation, and convective transport; and 3) landscape-scale impacts of fire on soils, vegetation, and atmosphere. The grand challenge is how to integrate the pre-, active-, and post-fire measurements and physical process models into a single robust and well validated framework.  [Read More]
