EMERGENCY POST-FIRE INTERVENTIONS IN FOREST LANDSCAPE
A very simple guide for regenerators
This flyer aims to raise awareness and to advice about strategies and techniques of ecological regeneration to owners of private properties or public entities that were afected by forest fires. Since the biggest priority is the soil protection, there must be taken measures to reduce erosion while structuring the landscape, creating infiltration opportunities to hydrate the land in a passive way making it humid, resilient, productive and biodiverse.
Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind, water, or by human activities (eg: tree cutting). Erosion risk in burned areas depends on soil type, the slope, the level of destruction and the rainfall patterns after the fire.
The soil stays exposed due to the complete destruction of organic matter, shrub and herbaceous layer.
Consequently, this layers stops to perform its function of water infiltration and the superficial runoff is accelerated. As soon as the first rain starts, the ashes and the soil are easily mobilized along the slopes by the absence of obstacles (branches, leaves, roots, etc.). The result is a nutrient loss, water pollution and an increase of the potencial of floods downstream of burned areas.
