Wildfire
Myths and Truths
By WILLIAM H. BANZHAF
It's wildfire season again in the United States. Hot, dry weather has
ignited blazes in at least 10 different states where wild fires are
consuming hundreds of thousands of acres.
It's also the season for laying blame and propagating myths as to why
our forests are suffering from another disastrous wildfire season. It's
time to put an end to these myths and put forth some truths about what's
best for the heath of our nation's forests.
The truth is that more than several decades of suppressing fires have
resulted in a heavy buildup of "fuel" --dead vegetation and
dense stands of dead and sick trees--and a shift to species that have not
evolved and adapted to fire. Because of these conditions, today's fires
tend to be larger, burn hotter, and spread farther and faster, making them
more severe. Forest scientists know that the best way to address the fuel
build up is to aggressively "thin" areas choked with deadwood
and underbrush.
Some myths being propagated include comments that thinning itself would
exacerbate the fuels build up and that a more effective method to
eliminate the fuels is to let the fires burn or more aggressively start
prescribed fires on public lands. The thinking behind these positions
should be carefully examined before we let one more acre of our public
lands suffer from wildfire.
Dr. Robert Lewis, deputy chief of the US Forest Service for research,
recently laid out the lack of scientific basis behind the "let it
burn and no management" philosophy to combating the fire problem. Dr.
Lewis told a House subcommittee "that it is the duty of the
scientific community to be as clear as possible about what is known and
not known...and to correct distortions and misrepresentations." He
said the following:
Cutting trees does not make stands more susceptible to later fires.
Dr. Lewis pointed out modern forest management techniques are far
different from the unscientific forest clearing that took place
decades ago; "Thinning trees in conjunction with subsequent
prescribed burning is an effective strategy for reducing fire
risk," said Dr. Lewis.
Letting fires burn is not OK. Dr. Lewis pointed out that "in
much of the West, fuels have accumulated so much that fires left to
burn can quickly become extreme events with a range of devastating
consequences," noting that watersheds and wildlife habitat suffer
when overstocked stands go up in flames.
Using only prescribed burning to reduce fuels is not sufficient.
Dr. Lewis noted that many Western forests have missed so many fire
cycles that they "require mechanical thinning before any
prescribed burning can be done safely.
The professional land managers and researchers in the Forest Service
and with- in the profession of forestry recognize that our national
forests are suffering from a serious forest health crisis; 76 million of
the 191 million acres in the system are at moderate to high risk of
catastrophic wildfire. These are not fires that will create wildlife
habitat, protect recreational values, and assure clean water in our
streams. These are fires that will destroy stands of trees, ruin
watersheds for long periods of time, and endanger homes and property.
The Forest Service and professional foresters are trying everything in
their power to work with communities to find solutions. One such effort is
its experiment with "stewardship contracting" projects to reduce
fuel loads and protect watersheds. Many of these projects seek to take
advantage of local knowledge and local businesses to improve forest health
by careful thinning and management of stands that have been neglected for
too long. In many cases, these projects will create value in the form of
wood products, which the agency can use to offset the cost of the work.
Some dismiss these efforts and simply assert that they don't trust the
Forest Service and that they oppose all commercial use of trees grown on
national forests. Through protest, political pressure, and lawsuits, they
are making every effort to stop these projects and prevent the agency from
doing more of them in the future.
The solutions to the wildfire problems are known, but obstructionists
are using myths to block attempts to implement them. The public deserves
better.
