Short Course on Forest Fire Effects on Soil Properties (co-organized)
Convener: Paulo Pereira  | Co-Conveners: Antonio Jordán , Guillermo Rein , Claudio Zaccone , Lorena M. Zavala 
Thu, 01 May, 10:30–12:00

Description and scope
Fire is a global phenomenon with important implications in many world ecosystems. Tropical, temperate, Mediterranean and boreal areas are affected recurrently by fire, which has shaped these ecosystems, altered their characteristics and changed their distribution. Thus fire is considered as a natural element with a wide range of diverse impacts. Among these, the impact on soils is the objective and focus of the course.
Soil properties can be substantially changed in space and time after fire. These changes can produce positive or negative impacts on the system, depending on the type of soil affected and fire severity. Fire severity and the degree of change depends in turn on fire behaviour and temperatures reached in soil, the residence time, and other biophysical variables (ecosystem type, fuel characteristics, topography, weather, etc.).
These changes can lead to deep post-fire changes in the ecosystem. Vegetation canopy is dramatically reduced by burning, increasing soil erosion risk and altering soil properties as water infiltration rates, hydrophobicity, structure, chemical and biological properties. In addition, the ash deposited has important physical, hydrological and chemical effects. The importance of these impacts depends especially on the post-fire conditions (wind and rain) and topography of the burned area. The combined degree of all these variables determines the ability of the ecosystem to recover.
