Bushfire

By Emma Williams

define the problem

A bush fire is when fire starts to burn bushes and trees and stuff on the ground and some of them are really hard to stop cause they can get really out of control and some people even light the fires on purpose and some people don't even know about it and if the busfrie gets really bad it can spread more and more and even reach houses

List the cause of the problem

Bush fires are common throughout Australia there made more likely when the weather is very hot and dry the higher the temperature the more likely it is that a fire will start or continue to burn they start from human activity deliberate or accidentally.

state the effect this is having on the enviroment

Not all plants respond the same way when burned by a bush fire. Some die, others re sprout, and others still appear little affected. Some of these differences are due to the individual species, some are due to the characteristics of the fire, and some may be due to the particular environmental conditions before and after the fire.

state the effect that fire has on wildlife

Fires can have an impact on native animals. In most cases populations will not be affected as native animals will recolonize a burnt area from surrounding areas after a fire. Where a species population distribution is limited or the species is listed as vulnerable or endangered on the however, a significant fire event can impact these populations.

Native animals can escape fire by fleeing to unburnt islands within the burn area or to surrounding unburnt vegetation. Insects, reptiles and small mammals may be able to hide underground and arboreal animals will move up into the treetops to escape low to moderate intensity fires. Birds are the least impacted as they have the ability to fly away however, chicks and eggs can be impacted depending upon the season of the fire.

state the effect that fire is having on humans

If you have heart or lung disease, such as congestive heart failure, angina, chronic obstructive pulmonary disease, emphysema or asthma, you may experience health effects earlier and at lower smoke levels than healthy people.

Older adults are more likely to be affected by smoke, possibly because they are more likely to have heart or lung diseases than younger people.

Children also are more susceptible to smoke for several reasons: their respiratory systems are still developing; they breathe more air (and air pollution) per pound of body weight than adults; and they're more likely to be active outdoors.

what has benn done to minimise the effects of the issue of fire

Bush fire is not a new phenomenon and is part of the natural ecology. In many countries, such as Australia, bush fire has been a necessary part of the life cycle for several native trees and plants, some of which have characteristics which promote the spread of fire, such as loose, flammable bark, and combustible oils in their green leaves. The Eucalypti in Australia is a good example. Bush fires also occur regularly in many other areas of the world, the most recent examples being the major series of European fires in the summer of 2000,2 and the 1997 bush fires in Southeast Asia, which burnt an estimated 5.3 million hectares.3 What is new over the past century, is the establishment of human communities in the bush settings where these fires occur. This can lead to greater fuel levels in the bush, increasing both the frequency of bush fires and the at-risk population when fires do occur.

possible solutions to the problem

We are very concerned about the declining bush fire protection standards in Victoria and the vital need to work with the authorities to turn them around. We see Black Saturday as a symptom of declining standards. It was not one of those one off disasters that happen each generation.Victoria, Australia is one of the most bush fire prone areas in the world. We need to get it right so we can protect our own and then teach other.
