In March of 2011 FPInnovations staff traveled to Rainbow Lake to create research plots in a prescribed burn unit. Work was conducted using a Gyrotrac GT-18 rotary mulcher, creating three ‘grid-mulched’ plots along with several ‘control’ lines. The grid-mulched areas are to evaluate their effectiveness as fuel reduction treatments, and the control lines were established to monitor their effect on fire behaviour. Work was completed over a three day period.
