BUSHFIRE RECOVERY

Following the devastation wrought by an out of control fire, the speed with which Australian flora recovers from such a disaster is always surprising. This is the result of millenia of adaptation to a fire-prone landscape.
The two "before and after" photos underneath were taken exactly 10 months apart.

The Australian flora has a number of methods to promote post fire regeneration.




Probably the best known is the ability of
Eucalypts to resprout from epicormic buds under the bark of the trunk
.

Eucalypt lignotuber regrowth









Other varieties have a lignotuber at the base of the tree that puts out fresh growth.











Yet more plants like this Exocarpos cupressiformis can resprout from burnt limbs if these are not too badly damaged.

Acacia melanoxlyon regrowth





Acacia species such as this blackwood,
although totally destroyed above ground by fire, can resprout from underground roots or runners.


Many smaller plants, such as the Bulbine lily naturally emerge from underground tubers which usually survive fires, whilst the seeds of plants like daisies can often likewise survive in the ground.

Daisies sprouting after fire
In Tasmania there is often a large display of  Diplarrena moraea (White Flag iris) after fires, which also emerges from underground tubers like the Bulbine lily.
