In many cases, this degradation is precisely the cause of an increased risk of fire. However, the great forest fires can also mean, in some occasions, an opportunity to recover the natural values of ecosystems that had been degraded. For that reason, great fires are one of the main causers of change in the world's forestry systems. This new situation can exceed the capacity of living things to deal with these disturbances and, in the last instance, to provoke the collapse of the ecosystems that provide them with a home. However, the current conditions of climate change and the intense and frequent changes in the natural world caused by human activity have introduced a change in the dynamic of the great fires. In it, they highlight that, all over the world, there are ecosystems that are vulnerable to fires, and that there are numerous organisms living in them that have developed evolutionary adaptations to cope with the natural cycles of fire.

So say the University of Seville teachers Pablo García Murillo and Vicente Jurado Doña in an article signed together with researchers from other universities in the review Science. The actions to recover the environment after a forest fire must be directed towards favouring more resilient and less flammable natural vegetation, which is better adapted to the new climate conditions it will have to live in. The fires that occurred in those places provided the people who manage them with an opportunity to change, via a suitable process of ecological restoration, the previous bad forestry practices. It is estimated that globally there are more than two million hectares of land in need of restoration.
