Wildland fires that threaten populated areas have the potential to inflict devastating damage to communities and can also threaten the personnel working on the fire. This lesson introduces the Situational Awareness Cycle. Learners practice using it to continuously monitor and adapt their support strategies and decision-support information depending on the rapidly evolving wildfire conditions. The lesson also discusses a range of tools that can be used to build and maintain situational awareness.
