How did the typography of Victoria's landscape aid the black Saturday bushfires?
The areas where many of the bushfires occurred in Victoria in 2009 are characterised by densely treed mountain slopes. Fires move more quickly uphill, so this meant that not only did the fires move through the countryside rapidly, but they were fed by the fuel of the thick vegetation. This resulted in more intense fires which were very difficult to extinguish.
What are the disadvantages of fire in Australian ecosystems?
Disadvantages: Fire can cause soil damage, especially through combustion in the litter layer and organic material in the soil. This organic material helps to protect the soil from erosion. When organic material is removed by an essentially intense fire, erosion can occur. Heat from intense fires can also cause soil particles to become hydrophobic. Rainwater then tends to run off the soil rather than to infiltrate through the soul. This can also contribute to erosion. In actuality, the negative effects of fires on soils are often exaggerated, and many fairly intense fires in western United States forests cause little soil damage. There is also the potential for alien plants to become established after fire in previously uninfested areas.
