In managing ground fires, what indicates the areas that have not burned?

The green color is indicative of areas that have not burned in managing ground fires. Vegetation that has survived a fire typically retains its green color, signaling that it has not been affected by the fire. In contrast, areas that have burned will display dry, brown, or gray shades, often resulting in a stark difference from the vibrant hues of healthy vegetation.

Recognizing these green patches is crucial for firefighting efforts, as it directly informs firefighters about where the fire has not spread and can help guide their preventive measures or further planning for extinguishing the fire. Identifying unburned areas also assists in assessing the fire's behavior and potential spread, which can be vital for safety and effective management during a response.
