Composite Burn Index (CBI) Photo Series


The Composite Burn Index (CBI) Photo Series uses plot data and photos to illustrate the range of burn severity encountered in different ecosystems of the U.S. We selected examples from over 2,500 plots and 85 fires, spanning very low to very high degrees of ecological change from fire. The series offers managers and scientists a way to calibrate their field interpretations, providing a sense of what the CBI represents visually on the ground. It offers insight into the variety and combinations of fire effects that make up the overall post-fire condition on a site.

Regional Photo Series

The photo series are organized under each region in two ways. One series groups plots in three ranges of CBI (0-1, 1-2, and 2-3) in order to view relatively similar plots together on the same page, and see the variety of fire effects that fall within each range. These groupings are not intended to infer any particular severity class; they are simply an equal numerical division of the full CBI range. The other series arranges the same plots in an abbreviated sequence of low to high CBI scores all on one page. This arrangement helps illustrate the gradient from very low to very high severity, and reflects the broad range of conditions possible from fire. In either series, click on thumbnail images for a larger photo and more detailed description of the plot.
