Prescribed Burning Guidelines
in the Northern Great Plains
Confining Fire
Mowing and haying
Firebreaks made by mowing or haying are probably the least desirable of the confinement types especially if other techniques such as wetlining are not used at the same time.We recommend that mowed or hayed firebreaks be extremely wide. The cut vegetation should be removed prior to setting the fire, and the prescription should call for a constant wind direction and speed.
Although this type of firebreak can be established several days in advance, more workers and perimeter surveillance are necessary to prevent fires from escaping by burning across vegetation that remains after mowing or haying, even though the fuel may be low to the ground.
