Fuel Break

"Fuel break - a barrier or a change in fuel type or condition (to one that is less flammable than that surrounding it), or a strip of land that has been modified or cleared to prevent fire spread. In the event of fire, may serve as a control line from which to carry out suppression operations." - https://www2.gov.bc.ca/gov/content/safety/wildfire-status/about-bcws/glossary
