SAF Fire Management & Prescribed Burning 3

Question 1

Crown fire initiation is most directly related to which fuel characteristic?

Accepted Answer

Canopy bulk density and ladder fuels

Answer

Crown fire initiation depends on canopy bulk density (the mass of available canopy fuel per unit canopy volume) and the presence of ladder fuels that carry fire vertically from the surface into the crown.

Question 2

The 'Watch Out Situations' in wildland fire safety total how many situations that firefighters should recognize?

Accepted Answer

18

Answer

The 18 Watch Out Situations complement the 10 Standard Firefighting Orders and describe specific conditions or circumstances that have historically preceded firefighter fatalities.

Question 3

Which factor does the Haines Index primarily measure in relation to fire weather?

Accepted Answer

Atmospheric instability and dryness that can contribute to erratic fire behavior

Answer

The Haines Index (Lower Atmosphere Stability Index) combines temperature lapse rate and dew point depression to indicate the potential for dry, unstable air that can contribute to large, erratic fire behavior.

Question 4

In a prescribed fire plan (burn plan), the 'prescription' is best defined as:

Accepted Answer

The range of weather and fuel conditions under which the burn will achieve objectives safely

Answer

The prescription specifies the acceptable ranges of weather parameters (wind speed, relative humidity, temperature) and fuel conditions within which the burn must be conducted to achieve management objectives while maintaining control.

Question 5

The practice of using fire to create a heterogeneous mosaic of habitat patches in a forest is primarily associated with which management goal?

Accepted Answer

Wildlife habitat diversity enhancement

Answer

Creating a fire-maintained mosaic of burned and unburned patches provides diverse structural stages and edge habitat that supports a greater variety of wildlife species compared to homogeneous stands.
