Earth Healing Itself
A forest fire isn't the end of the forest. In fact, it's a brand new beginning and a chance for new vegetation and greenery to spread in the blackened areas.
For instance, there are many seeds stored in the forest floor and they germinate after a fire. While new branches sprout from the basal buds of dead trees.
What's more, some plant species actually need blazes in order to grow. For example, the seeds of plants like jack pines and lodgepole pines are sealed tightly with a resin that can only be broken at very high temperatures.
