Final answer:
Heavy fuels are the classification of fuel that includes large brush, which affects forest fire behavior and fire management strategies.
Step-by-step explanation:
The fuel classification that includes large brush is referred to as "heavy fuels". These heavy fuels often consist of forests, thickets, and dense brushfields. They are characterized by large diameter materials such as downed logs, stumps, and dead trees, and can take longer to ignite due to their size and moisture content.
The presence of large brush can significantly affect both the behavior of forest fires and the strategies used for fire management and containment. Understanding fuel classifications is crucial in the development of effective fire prevention and control measures.
