The rains came at last and probably most across Western North Carolina
breathed a collective sigh of relief. The fires will be extinguished.
The woods will be safe. But safe from what? Safe for whom?
There is presently a burning debate regarding the role of wildfire throughout
the ecosystems of the planet. Simply put, fire has two origins —
natural and human. Lightning is by far the most prevalent ignitor of
natural fire. Hot lava can start fires and a minute percentage of naturally
caused fires are the result of friction and/or biological activity.
Human caused fires probably make up 90 percent of all wildfires in the
East. Human caused fires fall into two categories — intentional
and accidental. Accidental fires account for most human caused fires
and the sources are myriad; burning leaves, camp fires, cigarette butts,
electrical, mechanical, etc. Intentional fires are either arson or prescribed
burns.
In an almost surreal paradigm of paradoxes, fire is good and evil; useful
and destructive; worshipped and loathed; nurtured and suppressed. And
the progenitor and destroyer, the proponent and opponent of fire is
one: man.
From a historical, environmental perspective fire was as much a part
of the ecosystem as wind, rain, ice and floods. But from an anthropological
perspective it was a force that could be harnessed.
Without a doubt, fire was the most influential tool co-opted by primitive
homo sapiens. It pierced the darkness and provided warmth. It would
become the catalyst for transforming tool making and diets, creating
sedentary rather than nomadic civilizations and eventually sparking
the industrial revolution.
Natural fire co-evolved with the planet; anthropogenic fire co-evolved
with humans. Fire has forever been a part of the landscape. Some environments
and specific plant and animal communities require fire for their existence.
This is particularly true of the western U.S. and the southern and Atlantic
coastal zones where lightning fires are common.
But even in the Appalachians, there are fire dependent species. Table
Mountain pine, a species endemic to the southern and central Appalachians,
requires fire to open their cones and disperse seeds. Many believe the
oak and (formerly) chestnut forests on the drier southern slopes and
ridges throughout the Appalachians were maintained through fire.
The federally endangered red-cockaded woodpecker resides in open pine
forests, free from brushy undergrowth. Plants like goldenseal, purple
fringeless orchid, Indian grass and whiteleaf sunflower all benefit
from wildfire.
Microscopic pollen grain and charcoal samples from bogs across the Appalachians
point to fire as a common occurrence.
According to some researchers, it is too common to be solely caused
by nature. The proposed theory is high precipitation (50 inches or more)
across the region and the fact that most lightning strikes would be
associated with this rainfall and occur in summer months when moisture
was high and fuel load low point to a high incidence of anthropogenic
fire.
The use of fire by Native Americans in the Appalachians is well documented
by early European explorers. By the time whites made their way along
the Little Tennessee, the Tuckasegee and other waterways they found
established Indian villages that used fire in many fashions —
to create agricultural land, to enhance harvest of natural foods such
as acorns and chestnuts, to make travel easier and to protect villages
from natural-caused wildfire.
When Europeans first arrived, their lust for property and resources
led to the zealous and rampant use of fire to establish homesteads,
create croplands and promote slash and burn forestry. Then, just as
quickly, on the heels of this pyro-age came fire suppression.
With homesteads established, villages built and emerging societal order,
protection of personal and community property and identity became paramount.
Wildfire was now a threat to civilized existence.
And this spread of civilization shows no sign of abating. More and more
wildlands are lost to development and private homes and entire cities
snuggle close, within a fires breath, to national parks and forests.
Managers of these wildlands face many dilemmas. When is fire good? When
is it dangerous? How much is enough? Where and when to let fires burn
where and when to suppress?
These are the questions sparking the national wildfire debate. They
are important questions. Presently there are many more questions than
answers and the issues often parody wildfire with hotspots (what about
smoke pollution?) flareups (salvage timbering) and breakouts (what is
the history of wildfire — what is the ecology of wildfire?)
Perhaps the recent Sharp Fire in the Great Smoky Mountains National
Park will help shed some light. It should be noted that the Sharp Fire
is believed to be arson. The Park Service has offered a $5,000 dollar
reward for information leading to the arrest and conviction of those
responsible. Hopefully the perpetrator(s) will be caught and prosecuted
to the fullest extent of the law. Arson is a sick crime and has nothing
to do with thoughtful deliberations regarding wildfire.
But the Sharp Fire may be able to teach us some things. The largest
fire in park history (more than 7,000 acres) was ignited under tinder
box conditions, yet according to GSMNP fire ecologist Bob Dellinger,
Most of the forest had minimal resource damage. There were a few
areas that burned fairly intense, so there will be small, isolated areas
with significant mortality to the trees. In most cases it will probably
help restore the oak forests to a more natural state.
Further research by Dellinger and park botanists will document the recovery
of the area and provide more information on the long term effects of
the Sharp Fire. This data could help park fire managers and other land
managers across the country assess the pros and cons of wildfire and
aid in coming to grips with the role of fire in our wildlands.
