What is the Fire Behavior Triangle.
Weather, Topography, Fuel
|
What is the main causes of wildfires.
Campires left unattended, the burning of debris, equipment use and malfunctions, negligently discarded cigarettes, and intentional acts of arson.
|
What is fire intensity levels.
Low, medium, high.
|
What is Fire Regime.
The pattern, frequency, and intensity of the bushfires and wildfires that prevail in an area over long periods of time.
|
What is main fuel sources of ground fires.
Grass
Needles Leaves Plant roots |
|
What is slope, aspect, elevation, features.
Topography Factors
|
What is fire suppression policies.
Increased available fuel sources are caused by:
|
What is how fire intensity is determined.
The amount of spread of the fire, flame height, and the amount of energy produced by a fire.
|
What is examples of Fire Regime Change.
Fires are now harder to extinguish, require more resources, and carry greater risk of damage and costs.
|
What is passive, active, independent.
Types of Crown Fires.
|
|
What is the Venturi Effect.
When wind accelerates in the gaps between mountain tops. (Can also be seen in alleyways at times)
|
What is the percent of fires started by humans.
Nearly 85%
|
What is an example of how plant chemistry could affect fire intensity.
Conifer needles contain oil that increases fire intensity more than green maple leaves
|
What is ground fires can travel underground past firelines and reignite on the other side
A concern regarding ground fires.
|
|
|
What is Ground to Surface to Ladder to Crown.
The path fires take to move from undergound to the tops of trees.
|
What is reduce available fuel, native species growth, add nutrients to the soil, and controlling the insect population.
Benefits of fires
|
What is a quantitative measure of the effects of a fire on the environment, typically considering both the damage to vegetation and the impacts on the soil.
Fire Severity definition.
|
What is Oxygen levels/Concentration
Weather Conditions Topography(Whether it is up or down slope) Fuels amounts Size of the fire
Factors that increase the spread of surface fires.
|
|
|
What is: Wind (20+ miles @ slightly above ground level), Temperature (80*F +), Relative Humidity (20% -)
The three aspects of a Red Flag Warning.
|
What is increase the likelihood of "very large fires," intense fire weather conditions, longer fire season.
Effects of greenhouse gas emissions on climate.
|
What is Low Fire Danger – green
Moderate Fire Danger – blue High Fire Danger – yellow. Very High Fire Danger – orange. Extreme Fire Danger – red.
Different levels of fire severity and colors for each level.
|
What is Thinning.
Manage the amount of trees in one area including small shrubs. Cut dead trees. Put out fire before reaching tops of trees.
Ways to manage crown fire environments.
