Also similar is the need for fire or smoke to trigger some Australian native
seeds out of dormancy, or to open their casing. Bushfires are part of nature
here so as it rages through, the seed will open and smoke will cause a
chemical reaction to bring it out of dormancy, then it will germinate.

Even still, you can simulate the effect with smoky water.

The parent plant may die, but it's natures way of avoiding extinction.

Note likely since most eucalypt trees have a lignotuber just below the
ground.
