An Assessment of Fuel Treatment Effects on Fire Behavior, Suppression Effectiveness, and Structure Ignition on the Angora Fire

Fire Effects of Other Vegetation Management Areas

Description

Approximately 850 acres within the fire perimeter have had other vegetation management activities in the recent past. Most of these treatments were commercial thinning or salvage logging. Limbs and tops remained on much of the sites. Only roadside logging slash was treated. These mid-1990 activities were not designed or located for fuel reduction objectives.

Fire Behavior

Fire behavior within these areas was very similar to the non-treatment areas. Most of the areas burned with high intensity crown fire.

Suppression effectiveness, structure ignition, and public safety/egress

Suppression effectiveness was also similar to the non-treatment areas. Unit 5, adjacent to the high school, was the only vegetation management unit adjacent to structures. This was a helicopter commercial salvage logging unit completed in 1995. The high school buildings were constructed of fire resistant materials and were easily defended by engines and handcrews. No evidence was found to indicate that vegetation treatments had any bearing on public safety in this area.
