Buildings and homes that lie within the path of a wildfire are destroyed, exposing hazardous materials that pose a threat on human health for first responders and during the clean up process.
What are the elements that make up a wildfire?
Three elements are crucial for the creation of a wildfire: fuel, oxygen, and heat. Firefighters often refer to this combination of elements as the fire triangle. On a hot day, drought conditions peak and something as small as a spark has the potential to create a large wildfire with devastating consequences.
What happens when a forest burns?
As a forest burns, large amounts of smoke are released into the atmosphere. These smoke particles are typically small and made up of gases and water vapor. Air pollution from fires have the potential to travel great distances and oftentimes may pose a threat to human health.
How Forest Fires Start
Three elements are required in order for a forest fire to start: fuel, oxygen, and a heat source. Fuel is any flammable material, and a forest is full of these—trees, brush, grass, and small cabins. The air provides oxygen, and both humans and the environment have the ability to provide the heat source.
Types of Forest Fires
There are two different types of forest fires: surface fires and crown fires. Surface fires spread along the ground of the forest. Twigs, dry leaves, and other debris are engulfed in flames as it spreads. Crown fires burn trees up their entire length and spread quickly through the canopy.
How Are Forest Fires Fought and Contained?
Forest fires are contained by a wide variety of strategies, depending on the location and size of the fire. For smaller fires, firefighters often use a tool called a “flapper” to smother small patches of fire and stop spreading. A line of vegetation is cleared around the fire to further avoid spreading.
Human Impact of Forest Fires
Forest fires can quickly wipe out large patches of land or destroy many homes and local businesses, taking lives in the process. Firefighters who risk their lives to fight the fire can develop serious health problems due to smoke inhalation.
Environmental Impact of Forest Fires
Forest fires are often devastating to the environment. Ground cover is necessary to protect the soil. If all of this vegetation is burned away, the soil is left exposed to the elements. Heavy rain can degrade soil and cause flooding and erosion.
Controlled Burns
There is only one particular instance in which forest fires are intentional. Controlled burns are often used by forest management to benefit the forest. This puts a whole new spin on the phrase "fight fire with fire."

How did Aboriginal people influence the environment?
Aboriginal people influenced the environment by using fire to manage ‘country’. The practice has similarities to the prescribed burning techniques used today. The human influence on fire has affected the Australian landscape for centuries and this, in turn, has shaped the Australian flora and fauna. The impacts of fire on the environment depend on the fire history or fire regime (the interval between fires, the time of year fires occur, how intense fires are and the amount and arrangement of burnt and unburnt patches in an area). The decision to manage fire for safety, protection, land management and regeneration does not change this.
Is Australia experiencing bushfires?
Under current global warming trends, Australia can expect an increase in bushfire activity. Recovery will prove more difficult during periods of drought, and biodiversity will comprise species that respond better to fire and arid conditions.
