Wildfire Hazard Mapping
Wildfires, often referred to as forest fires, involve the combustion of areas of forest, brush, or grass. Wildfire danger increase during times of drought or seasonal lower precipitation when the fuel moisture content decreases. Wildfires can be caused by human activity such as smoking, campfire use, etc., or by natural occurrences such as lightning strikes during extreme weather or volcanic activity. Wildfires can cause death, injury, and loss of personal property and forest resources.

Maps are used to study wildfire hazard in various ways. Maps can show current fire hazard by combining fuel moisture data with current weather conditions. Maps are used to depict current and historic fire events. GIS (Geographic Information Systems) can be used to model fire behavior based on input such as local terrain, prevailing weather patterns, and forest fuel characteristics in order to map local areas with increased risk.
Wildfire hazard mapping in the United states is a multi-agency effort. The USFS, NPS, BLM, NWS/NOAA and other federal, state of local agencies may be involved. Some useful wildfire hazard mapping resources are listed at left.
