Fire is a worldwide phenomenon with important ecological, social and economical impacts. Fire removes vegetation cover and exposes soil to erosion agents. The degree of soil exposure depends of fire severity, evaluated by the degree of vegetation disturbance from canopy cover through surface plants, litter and soil organic matter consumption, size of residual woody stems, characteristics of ash and char, and other factors. This post-fire evaluation sighificantly contributes to determining if the impacts of fire effects can be minimized by management intervention. In countries where wildfires are frequent (e.g. Mediterranean countries, United States, Australia, Russia) important amounts of money are invested to recover burned areas and to soil protect, including some methods that are ineffective such as tree plantation. During these activities, soil is subjected to a tremendous impact (e.g. use of machinery), increasing vulnerability to erosion and nutrient depletion thereby compounding the potential impacts of fire with the the effects of human intervention. Another relevant aspect is that in many circumstances vegetation can recover quickly without interventaion thus avoiding the concurrent costs and impacts of mitigation activities. In this course we aim to present to the participants examples of both efficient and non-efficient of soil restoration strategies following wildfires, including impacts of direct burned area management (e.g wood remove) and natural recovery trajectories without intervention.
