Two Sides of Fire

…. Fire can be destructive.

But it can be beneficial as well…..


Key points

Key Points

  • What Determines fire Behavior?

  • What happens in a forest with no change or lack of fire?

  • Fire kills disease, reduces harmful insect populations, and returns nutrients to the soil.

  • Forests need change to remain healthy.


Fire dependent species

Fire Dependent Species

  • Examples are longleaf and ponderosa pine

  • Fire dependent species need fire at regular intervals to remain healthy.

  • Red cockaded woodpecker in longleaf pine ecosystem.


Controlled uncontrolled

Low intensity, surface fire

Reduces fuel buildup

Increases health

Returns nutrients to soil

Increase habitat

High intensity

Can develop into destructive crown fire

Loss of habitat

Soil damage & erosion

Dangerous near urban interface

Controlled Uncontrolled

Forests that have burned within the past 50 years will usually burn near the ground


Points to ponder

Points to Ponder

  • Know Fire Triangle

  • Fire helps the forest change and renew.

  • A forest ecosystem that is not changing is dead or dying.

  • The relationship of Native Americans and fire.


Ecosystem management

Ecosystem Management

  • Prescribed burning: low level surface fire designed reduce brush, regenerate and renew the forest.

  • Salvage or thinning forest stands: to reduce competition, overcrowding, and to reduce fuel buildup

  • Natural prescribed burn: naturally occuring fires that are allowed to burn to accomplish the management objectives of the forest.
