Description and scope
Fire is a worldwide phenomenon with important ecological, social and economical impacts. After fire, soil is vulnerable and exposed to erosion agents, due vegetation cover removal. The degree of soil exposition depends of fire severity, evaluated by the degree of tree crown remove, litter and soil organic matter consumption, twigs diameter, ash colour, etc. This post-fire evaluation is important to understand if a burned area requires some intervention in order to minimize the impacts.
In countries where wildfires are frequent (e.g. Mediterranean countries, United States, Australia, Russia and others) important amounts of money are invested to recover burned areas and soil protect, including ineffective measures as tree plantation. During these activities soil is subjected to a tremendous impact (e.g use of machinery), increasing the erosion and nutrient depletion vulnerability. Thus, to the potential impacts of fire, the effect of human intervention can increase importantly the soil vulnerability. Other relevant aspect is that in many occasions is ignored the fact that vegetation can recover quickly to fire disturbance. In this course we aim to present to the participants efficient and non-efficient examples of soil restoration after wildfires, including impacts of burned areas management (e.g wood remove) and no intervention after the fire.
