A firebreak is a strip of either bare ground or fire resistant vegetation typically about 10 feet wide.

It is used to remove fuel in case of wildfires and control prescribed burns.

Firebreaks should be located on the
contour where practical to minimize the risk of soil erosion.

Firebreaks may be a component on most conservation
management systems that address prescribed burning
or wildfire prevention as part of the conservation
system to manage grasslands, woodland and wildlife
resources. Firebreaks may be temporary or permanent
and consist of fire-resistant vegetation, nonflammable
materials, or bare ground. Firebreak construction must
comply with applicable federal, state, and local laws
and regulations.
