Wildfires Josh Tanner Camille Evans Victoria Taufer
Surface – Most common type and burns along the floor of the forest, moving slowly and killing or damaging trees.
Ground – Usually started by lighting and burns on or below the forest floor in the human layer down to the mineral soil
Crown – Spread rapidly by wind and move quickly by jumping along the tops of trees.
What a Fire Needs: Fire Triangle
How a Fire Starts: • Carelessness by humans • Cigarettes • Campfires • Arson • Lighting • Natural Combustion
Inside the Fire: • Speed of flames • Intensity • Temperature • FIRE!!
California Fires: • Since 2007 over 271,000 acres destroyed by wildfires. • Billions of dollars spent on recovery so far. • Less expensive to fight fires than to prepare for them.
Why California’s a Hotspot? • Unnatural buildup of vegetation • Native plants depend on fire for reproduction • Fire season begins in October because of Santa Ana winds coming in. • Little rain = dry conditions in summer • Very hot climate
Up Close to the Fire: • California fire in progress
South Africa Fires: • Greatest threat is to grazing land. • Extreme dry conditions little rainfall make ideal conditions for fires. • Greatest affect on rural areas. • 2008 – Most recent fire with 45 dead.
How This Affects Utah: • We fit in most extreme danger zone in the U.S. • Population is greater here than on the plains of Africa. • Need to realize the danger is REAL here!
We Can Prevent Fires: • Bad Camper • 75% of fires caused by people. • Be careful and cautious when we are outdoors. • Put out ALL embers of fires we make outdoors.
Be Prepared: • Follow local codes in order to avoid restrictions on materials and plants. • Mark driveway, house number, and make sure firefighters can get to your home. • Make a family evacuation plan • Make sure family knows about wildfire danger.
Not All Bad: • Fires do good too: • Clear away debris • Speeds up nutrient recycling of soils • Clears away grass & shrubs to make way for new seedlings to grow.
Why Make a Difference: • Smokey says so: • Video • Keep people safe • Common sense will increase if used • Keep smoke from getting up in atmosphere. • Protect wildlife
