An area cleared of vegetation to remove the fuel sources from a fire.

Fuel break means a natural or a human-made area immediately adjacent to a structure or to a driveway, where material capable of allowing a wildfire to spread does not exist or has been cleared, modified, or treated to significantly reduce the rate of spread and the intensity of an advancing wildfire; and create an area in which fire suppression operations may more safely occur.

A wide strip or block of land on which the native vegetation has been permanently modified so that fires burning into it can be easier to extinguish. In areas where cheet grass is widespread, landowners or managers may install fuel breaks of some other, less fire-prone vegetation to reduce fire spread.
