Book Description
The behaviour of single point-ignition and line-ignition experimental fires was studied in upland black spruce-lichen woodland stands at Porter Lake in the Caribou Range of the Northwest Territories from June 26-July 8, 1982. The experimental burning project objective was to relate the head fire rate of spread (ROS) in this fuel type to the initial spread index (ISI) component of the Canadian Forest Fire Weather Index System. The experimental fire plots varied in size from 0.02 ha-0.65 ha. and the live tree overstory averaged about 1200 stems/ha and 5.0 m in height. The lichen layer averaged about 3.5 cm in depth. Three point-ignition fires, seven line-ignition fires, and one wildfire were documented over a wide range of burning conditions. A relationship for equilibrium fire spread in black spruce-lichen woodland stands was established.
