FPInnovations investigated the effectiveness of mowing grass to reduce potential fire behaviour in corridors in Alberta. Plots of grass mowed in the spring or the previous fall were spring burned alongside plots of standing grass, and fire behaviour was documented. Results showed that mowing does influence fire behaviour in grass, and that season of mowing affects fire intensity. Mowing the grass in spring decreased the fire intensity values by 50% relative to no mowing, and fire intensity values decreased by a further 50% if mowing was completed in the fall.
