The goal of LIFE REFOREST is to demonstrate a new strategy to mitigate soil loss associated to post-fire episodes in forest areas by applying a technosol based in organic waste inoculated with fungal species (mycotechnosol) in order to avoid soil erosion and boost natural regeneration of burnt areas. LIFE REFOREST solution will be based in a mycotechnosol, contained in a tube-shaped biodegradable net, acting as a bioactive barrier to retain soil structure from streamflow in a first stage, and to accelerate ecosystem recovery thanks to fast fungal mycelium development on forest surface. This novel mycotechnosol will also supply organic matter and nutrients to the soil, and local plant seeds to accelerate the restoration of the vegetation cover and promote water retention.
