Information About Bushfires

What are the main causes of bushfires?

What causes bushfires? Bushfires are the result of a combination of weather and vegetation (which acts as a fuel for the fire), together with a way for the fire to begin – most commonly due to a lightning strike and sometimes human-influences (mostly accidental such as the use of machinery which produces a spark). via

What are some interesting facts about bushfires?

Lightning strikes the earth over 100,000 times a day. 10 to 20% of these lightning strikes can cause fire. Manmade combustions from arson, human carelessness, or lack of fire safety cause wildfire disasters every year. An average of 1.2 million acres of US woodland burn every year. via

How are bushfires made?

Bushfires can be started by natural causes, such as lightning strikes, or by people (accidentally or on purpose). Materials such as leaf litter, bark, small branches and twigs, grasses and shrubs can provide fuel for bushfires. Dry fuel is more likely to catch fire and burn easily; damp or wet fuel may not burn. via

Where do bushfires occur?

How do fires burn? Bushfires occur often in south-eastern Australia where the weather is often hot and dry. Fire spreads by a process called heat transfer. This is when the material immediately next to a fire is preheated to the point where it gets hot enough to ignite. via

How can we prevent bushfires?

You can remove native vegetation around homes, strategically reduce fuel across the landscape, and construct fuel breaks and fire access tracks, as part of your overall preparedness. You can also discuss with your CFS Regional Staff how to manage bushfire risks while minimising the affects on native plants and animals. via

What is the impact of bushfires?

The immediate impact of bushfires can be devastating, with loss of life, livelihoods and infrastructure at the fire fronts; and increased morbidity and mortality in smoke affected regions, which can often be far from the fires themselves. via

What was the worst bushfire in Australia?

The Black Saturday bushfires were the worst in Australia's history, killing 173 people. Almost 80 communities and entire towns were left unrecognisable. The fires burned more than 2,000 properties and 61 businesses. via

Why is Australia prone to bushfires?

The Australian climate is generally hot, dry and prone to drought. At any time of the year, some parts of Australia are prone to bushfires. Bushfires tend to occur when light and heavy fuel loads in Eucalypt forests have dried out, usually following periods of low rainfall. via

Is a bushfire alive?

People sometimes think fire is living because it consumes and uses energy, requires oxygen, and moves through the environment. Fire is actually non-living. They use oxygen and produce carbon dioxide. Fire does the same thing, but it has no body or has no structured cell system. via

Do bushfires cause rain?

Intense fires generate smoke, obviously. But their heat can also create a localised updraft powerful enough to create its own changes in the atmosphere above. As the heat and smoke rise, the cloud plume can cool off, generating a large, puffy cloud full of potential rain. via

How did the 2019 bushfires start?

What caused the 2019–20 Australian bushfires? The NSW RFS reported that the Gospers Mountain fire was started by lightning on 26 October 2019 and 'burnt through more than 512,000 hectares across the Lithgow, Hawkesbury, Hunter Valley, Cudgegong, Blue Mountains and Central Coast local government areas'. via

Why are bushfires important?

Bushfire and ecology

Fire plays an important role in environmental ecology, and is needed to trigger natural processes, such as stimulating seed germination and bringing benefits to biodiversity. Research shows bushfires help provide nutrients that native vegetation specifically needs to rejuvenate and seed. via

How can we reduce bushfires in Australia?

  • regularly mowing the grass and raking up leaves.
  • removing weeds and pruning bushes and trees.
  • keeping garden beds moist through mulching or other non-flammable ground covers like pebbles.
  • regularly clearing leaves from gutters, roofs, downpipes and around the base of trees.
  • via

    What does Australia do to prevent bushfires?

    One of Australia's strategies to reduce the build-up of fuels in forest and grassland areas involves the deliberate burning off of these fuels by various fire and land management agencies. Land management strategies for fire prevention also require a community-based approach. via
