Backgrounder: Wildland Fires
From the Federal Emergency Management Agency (FEMA) - October 23, 2004
EMERGENCY INFORMATION
- As residential areas expand into relatively untouched wildlands, people
living in these communities are increasingly threatened by forest fires.
Protecting structures in the wildland from fire poses special problems,
and can stretch firefighting resources to the limit.
- If heavy rains follow a fire, other natural disasters can occur, including
landslides, mudflows, and floods. Once ground cover has been burned
away, little is left to hold soil in place on steep slopes and hillsides.
- A major wildland fire can leave a large amount of scorched and barren
land. These areas may not return to prefire conditions for decades.
If the wildland fire destroyed the ground cover, then erosion becomes
one of several potential problems.
DANGER ZONES
Danger zones include all wooded, brush, and grassy areas--especially
those in Kansas, Mississippi, Louisiana, Georgia, Florida, the Carolinas,
Tennessee, California, Massachusetts, and the national forests of the
western United States.
WHAT IS A WILDLAND FIRE?
There are three different classes of wildland fires. A surface fire
is the most common type and burns along the floor of a forest, moving
slowly and killing or damaging trees. A ground fire is usually started
by lightning and burns on or below the forest floor. Crown fires spread
rapidly by wind and move quickly by jumping along the tops of trees. Wildland
fires are usually signaled by dense smoke that fills the area for miles
around.
HELP YOUR COMMUNITY GET READY
The media can raise awareness about wildland fires by providing important
information to the community. Here are some suggestions:
- Publish a special section with emergency information about wildland
fires. Localize the information by printing the phone numbers of local
emergency services, the American Red Cross, and hospitals. Report the
areas most at risk from wildland fires and let people know of the advantages
of creating a fire safety zone around structures and of using fire-resistant
roofing materials when building or rereroofing.
- Work with local emergency services and American Red Cross officials
to prepare special reports for people with mobility problems on what
to do if an evacuation is ordered.
- Print local building codes and weed abatement ordinances for structures
built near wooded areas.
- .Report on the advantages of regular chimney sweepings.
- .Periodically inform your community of local public warning systems.
DID YOU KNOW...
- More than four out of every five forest fires are started by people.
Negligent human behavior such as smoking in forested areas or improperly
extinguishing campfires are the cause of many fires. The other cause
of forest fires is lightning.
- A prescribed fire is a fire that is purposely ignited by land management
agencies under controlled conditions for specific management objectives.
- The 1991 wildland fires in Oakland, California, caused 26 deaths and
148 injuries. The fires destroyed over 3,000 structures, left over 5,000
people homeless and resulted in $1.5 billion in damages.
- In 1990, hot, dry weather conditions in California contributed to
brush fires in Santa Barbara County that destroyed more than 600 buildings,
caused over $200 million of damage and killed one person.
- The greater Yellowstone National Park fire of 1988 destroyed or damaged
private structures, including 17 mobile homes, 4 dwellings, a general
store, 12 garages and outbuildings, 19 cabins, and several storage structures,
and burned 1,210,730 acres of wildland.
