Wildland Firefighter Training (S-130) Practice Test

Drought conditions can significantly increase wildfire potential primarily by creating drier vegetation. When there is insufficient moisture in the environment, the plants and trees become desiccated, making them more susceptible to igniting. This drying process not only affects live vegetation but also influences dead plant material, such as leaves and twigs, which can easily catch fire under dry conditions.

As vegetation dries out, it leads to an increased availability of fuel for wildfires. The amount of moisture in plant materials is a crucial factor in determining their flammability. In drought scenarios, the lack of water means that both live and dead fuels can easily reach their ignition temperatures, facilitating the spread of fire and exacerbating the overall wildfire risk.

This situation can create a feedback loop, where the increased frequency and intensity of wildfires can lead to further challenges in ecological recovery and exacerbate drought conditions, making it critical for wildland firefighters and land management agencies to monitor and respond effectively to these changing risks.
