The recent Sharp Fire that burned more than 7,500 acres in the Great
Smoky Mountains National Park near Bryson City was the largest wildfire
in the parks history. The fire, believed to have been deliberately
set near Noland Divide Trail on Nov. 10, burned for nearly two weeks.
More than 200 firefighters from several states assisted in suppressing
the Sharp Fire. Damage from the blaze — ignited during tinderbox
conditions — was minimal, and park service officials estimate
that only about $600,000 was spent containing it.
Many factors — including the condition of the forest, operational
logistics and suppression techniques — make the Sharp Fire a good
backdrop for the discussion of wildfire in the Southern Appalachians
and other wildlands. Wilderness managers use a combination of technques
to battle wildfires, including letting them burn and suppressing them.
In general, naturally-occurring fires are allowed to burn while human-caused
fires are suppressed. Even those parameters, however, must be adjusted
according to local conditions and human habitation. At this time, scientists
still disagree about the role fire played in the Southern Appalachians.
History of wildfire in the Southern Appalachians
Fire has always been present in the ecosystem, as long as there has
been lightning. Many of the forest ecosystems in the arid West and along
the Gulf and Atlantic coastal plains — where lightning fires are common
evolved as fire-dependent communities.
The Appalachians, though, with their high precipitation and high moisture
content are not as susceptible to lightning fires. Records show the
Great Smoky Mountains National Park averages just two lightning fires
per year. Ancient pollen and charcoal samples from pond and bog sediments,
however, point to a time when there was a much greater frequency of
fire in the Southern Appalachians. This higher frequency of fire is
attributed to anthropogenic — human-caused — activity.
The use of fire by Native Americans in the Southern Appalachians at
the time of first contact by Europeans is well documented. By this time,
American Indians were using fire to create agricultural fields, keep
travel corridors open, enhance hunting, and protect villages from naturally
occurring wildfire.
What is not clear — and is currently a much-debated issue in the scientific
community — is the extent to which fire was used by pre-Colombian native
peoples in the Southern Appalachians. There are those proponents like
Stephen Pyne of Arizona State University, Ed Buckner, professor emeritus
of the University of Tennessee, Paul and Hazel Delcourt of the University
of Tennessee and others who posit the theory that aboriginal peoples
of the Southern Appalachians used fire extensively, to the extent of
managing and manipulating entire ecosystems across the region. Delcourt
believes Native Americans selectively used fire to concentrate pure
stands of oak, hickory, walnut and chestnut in the uplands. According
to Delcourt these early peoples, used fire on an order of magnitude
that fundamentally reorganized the ecosystem.
Pyne writes: Fires influence on the environment, however,
extended beyond its valued service to humans, an aid-de-camp to wandering
hominids. It was applied directly to the landscape, and it was this
capacity that defined humanitys special ecological niche, that
made fire something more than a surrogate for talons, fangs, fleetness
or muscles. Anthropogenic fire endowed whole ecosystems, not merely
a species. Anthropogenic fire reshaped the structure and composition
of landscapes, recalibrated their dynamics, reset their timings of growth
and decay. Humans ability to manipulate fuels redesigned the environment
within which fire — either theirs or natures — had to operate.
Buckner believes the pre-Colombian landscape was most likely a mosaic
of open woodlands, grasslands and some closed forests. He believes the
immense closed eastern forests Europeans referred to in the 1600s were
actually the result of fire being taken out of the ecosystem.
Buckner believes native populations in the Americas before contact with
Europeans rivaled those of Western Europe. The theory is that early
contact with Europeans introduced smallpox and other diseases to indigenous
peoples that reduced populations by 90 percent in the 1500s. As a result,
fields converted to forests and understory overtook open woodlands.
Quentin Bass, an archaeologist in the Cherokee National Forest in Tennessee,
disputes those estimates of population density. Bass believes that during
the zenith of Native American population no more than 40,000 individuals
inhabited the 50 million or so acres of the Southern Appalachians.
And these were stone-age people with no machines, no plows, no
draft animals and no livestock, Bass said. Its inconceivable
that those people under those conditions could radically redesign the
ecosystems of the Southern Appalachians, he said.
Bass believes that looking at old-growth Appalachian forests is like
looking at forever. According to Bass, forest types and
ecosystems of the Southern Appalachians are dependent on slope, aspect,
elevation, edaphic factors and canopy type.
These things are permanent, he said.
Cove forests hardly ever burn, moisture content is too high and
rapid decay prevents fuel build up, Bass said.
Robert Zahner, professor emeritus from Clemson University concurs with
Bass,.
I dont believe fire had much to do with shaping Appalachian
forests except for the dry southern slopes and ridges, he said.
Zahner and Bass would both agree that Native Americans certainly used
fire. But they argue it was localized, in bottomlands around villages.
Zahner who lives part time in Highlands where Delcourt researched a
bog in Horse Cove, believes those results (evidence of cyclic burning
over the past 4,000 years) are accurate. He believes, however, those
results are specific for that site — a bottomland valley — and can not
be accurately extrapolated across the Appalachians.
Zahner also fairly bristles at the mention of all the anecdotal references
to the open woodlands of Western North Carolina recorded by William
Bartram, in the 1700s.
Ive read every word I could get my hands on that Bartram
ever wrote. The best I can make out is that Bartram spent three to five
days in the area, along the Little Tennessee River.
According to Zahner, the scenes Bartram depicted would be of the extensive
Cherokee villages that existed in those areas at those times.
The ecology of fire
Even scientists with diverse opinions agree there are some places within
the Southern Appalachians where fire is a welcomed part of the natural
scheme of things. Fire has always been a component of xeric southern
slopes and ridges. With the exclusion and suppression of fire in recent
times, table top, Virginia and short-leaf pine ecosystems are disappearing
from the Southern Appalachian landscape.
Gary Kauffman, a U.S. Forest Service botanist who works in the Nantahala
National Forest, believes fire will have to be reintroduced in some
manner to restore these ecosystems. He said when these ecosystems are
healthy, they promote a greater diversity of understory and herbs. Native
grasses like little bluestem, Indian grass and big bluestem appear to
respond well to periodic burning.
Other rare plants in the region that respond to fire include whiteleaf
sunflower, purple fringeless orchid, mountain catchfly and goldenseal.
According to Kauffman, burning would also be beneficial to maintaining
some Appalachian oak forests. According to reports from a recent Workshop
on Fire, People, and the Central Hardwoods held in Kentucky, oaks
and pines have been replaced by late-successional, fire-sensitive species,
such as maples.
While Kauffman touts the benefits of fire as a management tool and believes
it to be a natural component of some Appalachian environments, he is
also cautious: It is a tool, we have to monitor it.
Kauffman would like to see more detailed studies of the results of prescribed
burns across different ecosystems. He would agree that fire probably
plays no role in cove forests and/or mesic forests on north facing slopes
in the Appalachians, but it could and should have an integral role in
those specific habitats where it was once a prominent factor.
Prescribed burning was once widely eschewed by environmentalist and
preservationists as being a tool used by wildlife managers and foresters
to manipulate habitats for specific results. But as more research continues
to be done, the restoration potential of fire is receiving more attention.
Prescribed fires, however, are still fires and are potentially dangerous.
The monstrous Los Alamos fire of 2000 was a prescribed burn gone awry.
Fire suppression
While the debate rages over the benefits and dangers of fires in the
environment, they continue to occur. Fire managers — whether at the
federal, state or local level — still must respond to fires.
On Nov. 10, two distinct plumes of smoke were spotted near the Noland
Divide Trail in the GSMNP by N.C. Forest Service spotters. The park
was notified and immediately responded. Fire crews began to create a
fire line along the southern edge of the fire. The fire management team
began to plan a suppression strategy for what became known as the Sharp
Fire.
Because of funding constraints, fire fighting agencies across the country
have had to come up with creative solutions for battling wildfires.
According to Robin Kastler of the USFS, all federal wildland fire agencies
and the Association of State Foresters are part of the National Wildfire
Coordinating Group (NWCG). This group provides a network and logistics
for sharing firefighting resources nationwide.
Leon Konz, chief fire officer for the GSMNP, said the park fire management
team decided on Nov. 12 — after studying variables like resources needed
to fight the fire, continued dry conditions and the possibility of other
ignitions — to contact NWCG for assistance.
On Nov. 14, a fire incident management team made up of members from
state and county agencies in Florida and Texas arrived on the scene.
This team spent a transition day with the parks fire team and
then assumed responsibilities for suppressing the fire.
Konz said the NWCG is an amazing network. Because of standardized training,
fire managers are assured they will get qualified personnel through
the organization.
The recent discussions about fires role in the environment has
given agencies some leeway in addressing naturally caused fires. Policy,
however, dictates that any human caused wildfire be suppressed.
Konz said the first rule in fire suppression is human safety. Firefighters
are mandated to fight the fire as aggressively as possible while insuring
the safety of the firefighters. Dangers to public and private property
receive high priority. Fires are to be fought in the safest, most economical
manner possible to attain the desired results.
While some expressed dismay at what they considered the non-agressive
suppression of the Sharp Fire, Konz and operations chief Greg Cox of
Florida said the fire was addressed in the safest, most efficient way
possible.
On reconnaissance information gained from fire analyst David Kerr of
California and park staff, the incident management team decided to establish
the north control line along Pole Road Creek Trail. According to the
teams fire information officer, Tracie Bowen, because of treacherous
terrain and high fuel load it would have been unsafe to attack the fire
from any other locale.
The efforts of the 200 firefighters who battled the Sharp blaze and
the incident teams planning paid off. The fire was contained within
the initial control line and by Nov. 24 the fire was controlled.
GSMNP fire ecologist Bob Dellinger said there was minimal resource damage
due to the Sharp Fire. In fact, according to Dellinger it will
help restore the oak forests to a more natural state.
Perhaps studying the effects of the Sharp Fire will provide insight
into how fire might be applied to the landscape in the future.
