Bushfire 03
Bushfire 03 :
History: The natural fire regime in Australia was altered by the arrival of humans. Fires became more frequent, and fire-loving speciesnotably eucalyptsgreatly expanded their range. It is assumed that a good deal of this change came about as the result of deliberate action by early humans, setting fires to clear undergrowth or drive game. Plants have evolved a variety of strategies to survive (or even require) bushfires, (possessing epicormic shoots or lignotubers that sprout after a fire, or developing fire-resistant or fire-triggered seeds) or even encourage fire (eucalypts contain flammable oils in the leaves) as a way to eliminate competition from less fire-tolerant species. Some native animals are also adept at surviving bushfires
