Introduction/Background:
For countless millennia, fire has played a major role in
the ecosystems of our forests. Regular burns (started by
lightning and by Native American peoples) have contibuted
to the well-being and diversity of our wildlands by recycling
nutrients, preventing accumulation of fuels which lead to
catastrophic fires and by creating "open forest" conditions.
"Open forests" permit sunlight penetrations, which favors
diverse plant growth and thus provides food and habitat
for a multitude of additional organisms. During the 20th
century, however, our forest communities were drastically
skewed by the removal of this critical natural force through
nearly a century of fire suppression by well-meaning forest
managers.
In
this lesson, your students will study the benefits of naturally-occurring
fires in our forests. They will learn something of the history
of forest fire and fire suppression in the U.S. and prescribed
burn policies that are currently used by managers of our
public lands.
Directions/Activities:
1. (20 minutes) Have students read introductory reading,
"The Mystery of
the Vanishing Giants". This can lead to a class
discussion on human manipulation of nature's systems and
the idea that nature usually thrives best when humans don't
meddle.
2.
(30-50 minutes) Hand out copies of the comic book, the True
Story of Smokey the Bear, (U.S. Department of Agriculture,
Forest Service, published between 1960- 1969). If possible,
have actual Smokey the Bear posters (including old ones)
posted on your classroom walls. (Often available through
U.S. Forest Service).
Smokey
the Bear first made his appearance as "Poster Child" for
the U.S. Forest Service in 1945. Smokey the Bear with his
sincere, caring, warm-brown eyes and humanesque hands and
denim pants with neatly rolled cuffs, was revered by the
American public. His flat Stetson ranger hat gave him an
air of authority while the shovel in his hand let us know
that he was a no-nonsense kind of guy-on 24 hour emergency
standby to fight any fire. The pleasant, but very unconcerned
expression on his face assured us that he was dead serious
about his mission. Most often, his sincere, piercing eyes
looked directly into yours and he was pointing straight
at you-this made his message most personal.
In
the decades that followed, Smokey's message became possibly
the most successful mass media campaign in history. If you
doubt its success, just ask any American over 25 years of
age to complete this line: "Remember, only you can _________
__________ ________!!!
Now,
I would be burned at the stake if I suggested that Smokey
was a hypocrite or a liar. But may I be so bold as to hint
that Smokey's ideas were seriously skewed. Smokey's clear
message in the early years of his campaign was plain and
simple: any fire in the forest is bad, evil, in fact, demonic.
But the updated message, born out of decades of evidence
from fire research, is that all forest fires are not bad-in
fact, the vast majority of fires are highly beneficial to
our timberlands. The sad verdict…Smokey the Bear, more than
any figure in American history, is guilty of forest pillage
and destruction to a degree that is hard to imagine! In
his defense, we must grant that all Smokey's fire prevention
campaigning was well-intended. But we never should have
placed such blind trust in a bear…they do not rank high
on the animal intelligence scale.
- Have
your students read "The True Story of Smokey the Bear".Ask
them to pay close attention to the old posters inside
the front and back covers as well as any flyers on your
wall.
- Ask
students to summarize the message contained in the comic
in a written paragraph.
- Now,
show some of Smokey's late posters and discuss the subtle,
but important differences in his updated message.
- Inform
your students that they have contracted with the Forest
Service to design fire prevention posters for the new
millennium. Allow them to create and have each present
his/her poster to the class with an explanation
of the intended
message

3.
(40-45 minutes) Have students read "The Many Faces of Fire"
from the Yosemite Guide, Fall 1999 (by Mary Kwart,
Yosemite prescribed fire specialist). In addition, have
them read "Fire History" and "Student page…Fire in the 1980's"
from Project Learning Tree, The Changing Forest:
Forest Ecology, pages 84-85, 89.
Activity
"A"-
Discuss
the following questions relative to the article:
a)
Describe some of the ways that Native American used fire
to their benefit.
b)
Who was Gifford Pinchot and what was his philosophy regarding
forest fire?
c)
What was the "10:00 a.m. fire control policy"?
d)
Briefly describe the evolution of the "Let Burn" policy.
e)
Distinguish between a catastrophic fire and a management
fire. Describe two catastrophic fires that have occurred
in global history.
f)
What are two main strategies used in managing firs?
g)
How is it possible to use fire to prevent fire?
h)
Describe two Park Service occupations that relate to fire
management.
i)
Review the burned acreage statistics given in the article…what
percent of Yosemite National Park (Total park acreage=750,000
acres) has had a prescription burn? Lightning fire? What
percentage of the park has yet to see a fire in recent years?
4.
(40-55 minutes) Activity "B"-(Fire Crisis Role Playing Activity)
Fire
Scientists finally have agreed that the vast majority of
Sierra Nevada Forests are an "Inferno-In-Waiting," following
one hundred years dedicated to elimination of fire. The
Governor of California in conjunction with U.S. Directors
of the Park Service and Forest Service have appointed a
task forece to make recommendations on this critical issue.
Have
students volunteer to role-play the listed positions. Hold
a high-powered "Sierra Fire Summit" meeting in the Mark
Hopkins Hotel in San Francisco, and make recommendations
regarding solution to this Sierra Nevada Eco-Crisis.
Sierra
Fire Summit meeting participants:
- The
Superintendent of Yosemite National Park
- The
manager of Camp Sugar Pine, a youth camp located ten miles
southwest of Yosemite
- A
Fire Ecologist from the University of California
- An
Inyo National Forest Fire crew boss
- An
old-time Yosemite camper with Emphysema
- A
property owner from Foresta, a privately-owned tract within
the boundary of Yosemite, whose home was destroyed in
the devastating A-rock fire of 1990
- A
cattle rancher with a grazing permit for zones within
Sierra National Forest
- A
regular Yosemite backpacker/Sierra Club member from the
Bay Area
- A
State of California air pollution specialist from Sacramento
- A
reporter writing an article for U.S. News on Fire Ecology
- Tom
Roberts, owner/manager of Virginia Lakes Pack Station
- Citizens
from local communities-Mariposa, Oakhurst, Mammoth, etc.
Evaluation/Outcome:
Take
your students on a field excursion to Yosemite National
Park (or another park or forest nearest your school) to
witness first-hand the effects of fire on a forest ecosystem.
Plan to visit a minimum of two recent (i.e. - within the
past 15 years) burn sites, including a catastrophic burn
site (examples: The "A-Rock" (esp. the Foresta Area) or
steamboat fires of 1990- both are readily accessible by
road) and-a prescribed burn site (ex. - prescribed burn
below El Capitan, June, 1999).
Divide
your class into groups of 4-5. Each group should have notebooks,
VCR or camcorder and tape. Explain to the class that their
assignment (each group) is to produce a quality video commentary
(10-minute time limit) which will explain and demonstrate
the differences between a destructive (catastrophic) fire
and a healthy (prescribed) burn. Ask students to include
close-up footage of mature trees (dead or alive), shrubs,
herbs, and watercourses in each area to emphasize the differences
between a destructive and a healthy fire.
Also
included in each commentary should be a brief history of
fire suppression as well as an explanation of principals
of fire ecology and prescription fire management. Explain
that their productions will be used to educate fellow students/peers
across the country on this crucial subject of the Fire Eco-Crisis
of our Forests.
Upon
returning to your classroom, take a class period to observe
and review student commentaries. Allow the students to decide
which is most educational and television-worthy (or better,
have students who are skilled in video editing make up a
composite video involving numerous high-quality scenes from
several of the class videos)… you should submit it to an
educational television station for possible broadcast!
