Wildfire Management

Drought can be a contributing factor to wildfire. Dry, hot, and windy weather combined with dried out (and more flammable) vegetation can increase the probability of large-scale wildfires.

Key Issues

Drought and Wildfire Interactions

The relationship between drought and fire is complex. The timing, intensity, and frequency of drought events have divergent impacts on fuel flammability and fire behavior. Rapidly drying abundant fuels in forest understories and grasslands after a wet spring can feed larger fires. Prolonged drought can limit fire occurrence as the availability of fuels (e.g., grasses) is reduced due to lack of precipitation.

Reducing the Potential for Wildfires

Wildfire potential can be reduced in some forests in the West and South by thinning trees, prescribed burning, and letting fires that will not affect people burn. There are also actions that individual homeowners can take to create a defensible space, an area around a building/property in which vegetation, debris, and other types of combustible fuels have been treated, cleared, or reduced to slow the spread of fire to and from the building.

Cascading Impacts of Drought and Wildfire

Drought can impact drinking water supply, agriculture, and human health. When wildfire hits in drought-stricken areas, watersheds and reservoirs can be further impacted by ash and debris flows, water treatment facilities may shut down with damage or loss of power, crops can be destroyed, and smoke can affect animal and human health.

Drought in a Changing Climate

Drought, combined with warming temperatures, can result in decreased snowpack and streamflow, increased evaporative demand, dry soils, and large-scale tree deaths, which results in increased potential for large wildfires.
