Période

Used 1985 to present.

Canada

This type of pin was designed by Canadian Forest Service, Natural Resources Canada and was made and used in Canada, in experimental and wild fires. (ref. 1)

Fonction

Marker used to determine the degree of forest floor consumption by fire.

Technique

Depth-of-burn pins used to determine the degree of the forest floor consumption by fire. The pins are placed on grid throughout plot: 100 pins on a 1-ha burn. The pins is anchored in the mineral soil, so that the T-bar is flush with the top of the duff level [decaying vegetation covering forest floor]. After the burn has taken place, the new distance between the duff and the T-bar is measured. An average over the entire plot is calculated to determine the depth of bum which in turn is converted to fuel consumption through bulk density, measured in kg/m [squared]. Duff samples collected before the burn allow observers to measure fuel weights for different layers of the forest floor. (ref. 1)
