Which fuels typically include stumps and heavy timber?

Heavy fuels are characterized by their larger size and density, which includes materials like stumps and heavy timber. These types of fuels have a significant impact on fire behavior because they are more difficult to ignite and can burn for an extended period once they are ignited. Their mass and moisture content require higher temperatures and more intense heat to catch fire, which means they can sustain a fire for longer durations. Understanding heavy fuels is crucial for fire management and suppression strategies, especially in forested areas where such materials are common. Recognizing the presence of heavy fuels allows firefighters to predict fire intensity and behavior more accurately, which is essential for safety and effective fire control.
