Simulations of wildfire spread are needed for the management and study of wildfires in the vast sagebrush steppe of North America.

By comparing simulated fire-spread to actual wildfire patterns, managers and researchers can assess the accuracy of fire-spread simulations, but these simulations require information about the vegetation that serves as fuel. USGS researchers assessed the accuracy of the Fire-Area Simulator, or FARSITE, using different fuel-input options for the 2015 Soda Fire in Oregon and Idaho, USA. The researchers found that using satellite-derived vegetation maps to inform FARSITE resulted in a better simulation of fire spread when compared to other sources of vegetation information. In addition, this method accurately simulated fire-spread for the 2016 Cherry Road fire. This accurate method for simulating fire spread can help in understanding fire behavior, improve safety for firefighters, and inform wildfire fuel treatments.
