Mechanized full-tree logging is the preferred harvesting system in Northeastern Ontario. These operations typically involve roadside delimbing, producing large quantities of slash at roadsides and landings. Slash pile burning involves gathering the slash into concentrated areas and subsequently burning it in piles. This method of Slash disposal has not been consistently applied across Northeastern Ontario in the past. Slash pile burning is a very effective slash disposal method. Eliminating roadside slash piles will recover land for forest production and reduce wildfire hazard. Best results are achieved when slash is piled and cured before burning. Factors affecting the choice of ignition device are reviewed on Page 5. A decision key is introduced on Page 6 to assist managers in developing a slash pile burning strategy.
