Q

In what ways are small controlled fires different to large bushfires?

A
  1. Small fires only burn off some of the leaf litter, and many insects and decomposers on the floor survive. Large fires burn off most of the leaf litter, and kill most of the insects and decomposers.
  2. Small fires do not destroy fallen branches and logs, which provide shelter for animals. Large fires do destroy the branches and logs.
  3. Small fires leave patches of grass and shrubs, providing food and shelter for organisms. Large fires do not leave these patches.
