For many years, fire supression was used to controal and eliminate
wildland fires. This was thought to be the right thing to do. Over
time however, the duff, or underbrush piled up and fuel (the materials
that fire feeds on) was allowed to accumulate to the point that
were a fire to occur, disaster would almost certainly result.
More recently, research (and physical evidence) has shown that
allowing naturally occurring fires to burn is one way that nature
takes care of housecleaning. Forest resource management now uses
a technique called prescribed burns where they perform controlled
burning to help that process along. These methods have their supporters
and their opponents. While on the positive side controlled burns
help the health of wildlands, a prescribed fire that gets out of
control can quickly turn the tide of supporters against this policy
as evidenced in the summer 2000, Los Alamos fires.
Objectives
- Students will learn about wildland fires and what causes them.
- Students will learn about fire suppression versus prescribed
burn techniques.
- Students will learn about what conditions need to exist in order
for a fire to start and stay buring.
- Students will learn about the destructive force of fire but
will also learn why fire is necessary.
- Students will learn about plants that need fire in order to
survive.
Concepts
- How do wildland fires start?
- What 3 components are necessary for fire to exist?
- What possible benefits can result from wildfires?
