Fire breeds life as much as it destroys it. If they are not allowed to burn, that matter can be fuel for more deadly fires later.
Rain washes nutrients from burned matter into the soil.
Some animals thrive, such as birds, and they are able to locate prey more easily in the cleared brush. In some forests, the heat melts pinecone resin, freeing seeds to germinate. It can survive at up to 300 degrees. Fire destroys a chemical that keeps its growth enzyme inactive. After fire, trees produce seeds and shoots.
