On June 24, 2012, the GD1 plot was burned. The plot was designed to test whether crown fire would carry into a treated stand of 1m crown spacing. The plot was established June 2011 and was chosen because it naturally attained 1m crown spacing and required no additional overstory removal. Dead standing stems, understory spruce <3m, dead and down surface fuels and ladder fuels (branches below 3m) were removed.
Light winds (approximately 5 kph) were variable throughout the morning and early afternoon, but were predominately from the south. Ignition was at 15:36 along the south edge of the plot (Figure 1). Immediately following ignition, the light south wind shifted to a slightly stronger (5-10 kph) west wind carrying the fire towards the east edge of the plot. At approximately 15:42 wind shifted back to the south taking the fire towards the north.
Fort Providence Research Site, Located approximately 40km north of Fort Providence, NT just off Highway 3, the Fort Providence Research Site site was the location of the International Crown Fire Modelling Experiment (ICFME) between 1995 and 2001. Research activities at the site were taken over by FPInnovations Wildfire Operations Research team in 2001. Working closely with the Government of the Northwest Territories, FPInnovations is able to conduct field experiments using high intensity crown fires in support of numerous projects submitted by members.
