Yellowstone Fire Management History Early humans European
expeditions 1870s save the forests Suppress all fires Leopold
report (1972) Natural fire management Two zones Changed after 1988
fires Education Defensible space
Slide 9
1. What are some of the factors that contributed to high fire
danger in Yellowstone during 1988? 2. Name some reasons why the
lodgepole pine needs fire. 3. Since the lodgepole pine is the major
tree type found in Yellowstone, could you argue that fire is a
natural part of the ecosystem? Why or why not? 4. How would
Yellowstone Park be different with or without fire? 5. Was
Yellowstone Park ruined by fire? Why or why not? 6. What does
Yellowstone Park look like when those articles were written?
Slide 10
Daily Review #5 19. Describe how the U.S.s fire management plan
has changed over the centuries. 20. Define drought, crown fire,
prescribed burn, ground fire and back fire. 21. How do humans make
drought conditions worse? 22. If you did/do live in a forested
area, what would you do to protect your home from wildfires?

Bark Beetles Several different species Mountain pine beetle
Douglas-fir beetle Native Life cycle 1 year Larvae feed over the
winter Use glycerol
Slide 12
Types of trees Large diameter damaged trees Infestations = all
types Signs Pitch tubes Boring dust Woodpeckers Yellow to red
foliage Bluestain wood
Slide 13
Control Limited effect Woodpeckers Cold temperatures Bark
removal No chemicals Burning or burying Prevention Chemicals
Pheromones Healthy forests Limit infected products
Slide 14
Average Fire Year 24 lightning caused fires 83% burn less than
1.2 acres 94% burn less than 100 acres Detected at 3:03 pm
Slide 15
1988 Fire Statistics 9 human caused 42 lighting caused 36% of
park effected 63% of burned area due to fires started outside park
300 large mammals died $120 million spent fighting 25,000 people
involved
Slide 16
Creating the Perfect Conditions Wet spring Lush understory Rain
stopped Lowered moisture content High winds
Slide 17
You are interviewing to be the manager of the Lotsatrees
National Forest. As part of your interview, the interview committee
has asked you to put together a plan to manage this forest. Your
plan needs to have 2 parts. 1. A plan to manage the forest on a
daily basis (non-fire) conditions. 2. A plan to manage the forest
once a fire has broken out. Assume the fire started to the south
and wind is pushing it into your district. Each part of this plan
must have 3 different components. Give a creative presentation to
sell your plan and get hired.
Slide 18
Based on the plans you heard, select the best plan (you may
select your own). In a paragraph, describe which plan you selected
and defend why it is the best plan for the Lotsatrees National
Forest.
