Which term refers to a comprehensive term used for all the constructed or natural fire barriers?

The term "Control Line" refers to a comprehensive term used for all constructed or natural fire barriers. Control lines are established to halt the spread of fire and can include fire roads, ridgelines, rivers, or any natural feature that can serve to contain the fire. They are crucial in wildfire management as they assist firefighters in controlling and suppressing larger fires effectively.

In contrast, firelines are specifically the areas where vegetation has been removed to create physical barriers to fire spread, but they do not encompass all types of barriers. An anchor point is a specific location where firefighters can safely begin their operations, providing a secure base from which they can work. Mop-up refers to the process of extinguishing residual hot spots and securing the area after the main fire has been controlled. These terms serve specific purposes within wildfire management, but none provide the comprehensive scope of fire barriers that "Control Line" does.
