What is the term for fuels that are close together or touch each other?

The term for fuels that are close together or touching each other is contiguity. In the context of wildfire behavior and fire dynamics, contiguity refers to the spatial relationship between fuels. When fuels are in close proximity, it increases the potential for fire spread, as the flames can leap from one fuel source to another more easily.

Understanding contiguity is critical for firefighters when assessing fire risks in a given area, as denser fuel arrangements pose a greater challenge for controlling wildfires. This concept helps in planning effective firefighting strategies and implementing preventative measures.
