Fire Regimes
The two key attributes of LANDFIRE fire regime groups.
What are frequency and severity?
Energy released by fire.
What is fire intensity?
The three sides of the fire behavior triangle.
What is the 10 AM policy?
Fire regime characterized by a complex mosaic of low, moderate, and high-severity fire.
What is a mixed-severity fire regime?
Three factors that limit fire regimes.
What are climate, fuels, and ignitions?
Ecological effects of fire.
What is fire severity?
Heat transfer via movement of hot gasses.
What is convection?
Wildfire management strategy that allows for natural wildfires to burn with little or no suppression actions.
What is wildland fire use?
Two attributes of fire regimes that are not included in the LANDFIRE fire regime groups?
What is fire size and spatial pattern?
Fire regime characteristic of dry, open-canopy forests.
What is frequent, low-severity?
Forests with prolonged, linear stand development typically have _______________ fire regimes.
What is stand replacing?
Heat transfer via electromagnetic waves.
Legislation in 1911 that gave the Federal Gov't authority to suppress wildfire across ownership boundaries, and outlawed cultural burning.
What is the Weeks Act?
Satellites used for active fire detection.
What are MODIS/VIIRS?
Terrain and fuels are considered _______ controls on fire regimes?
What is bottom-up?
Type of fire adaptation that arises from frequent, low-severity fire.
What is fire tolerance?
Mathematical models of fire spread developed at the Missoula Fire Lab.
What are the Rothermel equations?
Socio-ecological feedback cycle that leads to increased effort and costs of fire suppression?
What is the wildfire suppression paradox?
Satellites used for detecting fire severity.
What are LANDSAT and Sentinel-2?
An attribute of fuels that is influenced by seasonality and climate.
What is fuel moisture?
What is fire responders (resprouters/seeders/serotiny)?
Large cloud that results in fire-driven weather.
What is a pyrocumulous cloud (or pyrocumulonimbus or flammagenitus)?
US Forest Service Strategy, published in 2022, providing investments in strategic wildfire risk reduction efforts.
What is the Wildfire Crisis Strategy?
__________ models are statistical models that are fit to replicate patterns in empirical data, while ___________ models are more complex models designed to simulate the processes and feedbacks that give rise to those patterns.
Phenomenological, process-based.
