  1. Two Sides of Fire …. Fire can be destructive. But it can be beneficial as well…..

  2. 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.

  3. 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.

  4. 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

  5. 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.

  6. 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.
