Prescribed burning and wildfires modifies biogeochemical cycles and, at least temporary, increase soil erosion due to the absence of a ground protective cover. Forest lands are usually located on steep slopes and have thin soils, consequently forest fires are a huge threat to soil, which sustain human life on Earth. This session will pay special attention to the different impacts of both prescribed fire and wildfire in different ecosystems across a full range of spatial scales (from soil microbial processes to landscape scale), temporal scale (from immediate to long-term) and bioclimatic stages. We wish to put together successful experiences with fire management (pre and post) in order to establish best guidelines to achieve their goals with minimal impacts on the environment. This session propose an exchange of knowledge on the evolution of soil properties and its hydrological response after fires.
