Northern Prairie Wildlife Research Center
Several types of firebreaks have been used on grassland fires in the NGP region. Primary among these are (1) bare or mineral soil and tilled farmlands, roads, or trails; (2) streams, lakes, and wetlands; (3) wetline; (4) chemical retardants; (5) foam retardants; (6) mowed or hayed, or (7) burned or blackline strips or areas; (8) flappers and backpack water pumps; and (9) snowbanks.
Usually two or more types of firebreaks will be used on any one fire. Do not forfeit prescription objectives to get by with an easier or cheaper confinement method. Remember, fires are more difficult and dangerous to confine than to set.
The primary types of firebreaks used by USFWS personnel are shown in Fig 33. In the prairie pothole region, combinations of bare soil, roads or trails, and streams or wetlands were used more than a single type.
