Wild Land Fire Ecology Kaylene Maize

Fire Management History  Full Fire suppression introduced after the fires of 1910  Fire was not allowed to burn, it was extinguished immediately  Today fire is seen as a natural and important role in a healthily ecosystem

An Ecosystem Perspective on Fire  Long-term goal: minimize destructive elements of fire while maximizing its benefits.  Prescribed fire is used to control unwanted plant species and to promote growth

How to Prevent Fires!  Fuel treatment:  Isolation  Removal  Rearrangement  Fuel distribution:  Ground fuel  Areal Fuel  Surface fuel  Crown fires

Smokey the Bear Educational programs can reduce the occurrence of unwanted fires School programs 4-H Boy Scouts/girl scouts Media announcements

Wildfire Suppression  U.S. Forest Service strategy is to “confine, contain and control.”  Fire attack  Direct- to build a control line at or close to the leading edge of a fire  Indirect- building the control line some distance from the fire’s leading edge. Use in large rapidly spreading fires

The Fire Triangle

Fire Behavior  Fire begins with ignition  Fuel- Moisture, continuity and arrangement  Weather- temperature, wind and relative humidity  Topography- Aspect, slope and elevation

Fire Regime  Components:  Time:  Frequency  Seasonality  Fire:  Size  Intensity  Classes:  Understory  Stand replacement  Mixed severity  Non-Fire www. century21-condesa.com

Major Fuel Types Grass Shrubs Timber Slash

Job Opportunities in Fire Ecology  Wild land Fire fighters  Smoke Jumpers  Fire engineer  Fuels management  Hot shot crews fire.lacounty.gov
