Fire Regimes
This component of a fire regime describes how often fires occur in a given area.
What is frequency?
This geological period marks when land plants evolved and fire became possible.
What is the Silurian-Devonian Period?
This term refers to intentional Indigenous fire use for managing landscapes.
What is Cultural Burning?
This ecosystem naturally burns in high-severity, stand-replacing fires.
What is Chaparral?
This 20th-century campaign symbolized fire suppression ideology in the U.S.
Whos is Smokey Bear?
This fire regime component refers to the timing of fire during the year.
What is seasonality?
These two natural ignition sources dominated before humans became major fire drivers.
What are volcanoes and lightning?
This type of landscape pattern results from repeated low-intensity burns.
What is a patch mosaic landscape?
This ecosystem is characterized by frequent, low-severity surface fires historically.
What is mixed conifer forest?
This policy required fires to be suppressed by the next morning.
What is the 10am policy?
This is the term for how intense or damaging a fire is to the ecosystem.
What is intensity?
This hypothesis argues that cooking with fire supported human brain development.
What is the cooking hypothesis?
This scholar argued for significant anthropogenic landscape modification.
Who is Anderson?
List a tree adaptation that allows proliferation after high intensity fires
This government agency was created in 1905 and played a major role in fire suppression.
What is the U.S. Forest Service?
This is the term for how large a fire is in total area burned.
What is size?
This concept describes how fire shaped plant traits like thick bark and serotiny.
What is fire as an evolutionary force?
Which researchers argued that lightning alone could explain many fire regimes (List 1).
Who are Barrett, Swetnam, and Baker?
This process occurs when too-frequent fire converts chaparral into grassland.
What is type conversion?
This natural condition, involving long periods without rain, makes fires more severe.
What is drought?
What are all 5 components of a fire regime?
What are frequency, seasonality, severity, size, and interactions?
This model describes four phases of human-fire relationships across time.
What is the Pyric Phase Model?
This is one main reason Indigenous people used fire.
Food/resource improvement
This ecosystem comparison highlights infrequent but high-severity fire regimes outside California.
What is Yellowstone?
This term describes the area where human development meets wildland and increases fire risk.
What is the Wildland-Urban Interface (WUI)?
