Thee Foundation of Fire Behavior: Fuel Loads andVegetation Structure

Vegetation serves as primary fuel source for any wildfire. The composition, density, nawilżone content, and horizontal and vertical arangement of vegetation directly control thee intensity, rate of spread, and resistance te to control of a wildland fire. A landscape dominate boy continuous, dry, fine fuels will support rapid fire spread, while areais with sparse or moist fuels will naturally regaid fire growth.

Fine Fuels vs. Heavy Fuels

Fine fuels, such as graches, pine eedles, andsmall twigs, are chacterized by a high surface area-to-volume ratio. Thii allows them to quickly gain and lose havure, making them receptive to ignition with in minutes of exposure to a heat source.

Mountain Waves andTurbulent Eddies

When strong wings flow architer too a mountain range, they create standing waves on downwind side.
