Abstract

Postfire restoration is meant to mitigate or reverse negative fire impacts. Impacts are related to fire regime and its interactions with ecosystem fire resilience. In the case of severe fire regimes, the main ecological impacts affect nutrient budget, soil-erosion risk, and the reduction of biodiversity. Planning postfire restoration requires the identification of the specific degradation processes triggered by fire, including their time and spatial dimensions, and vulnerable ecosystems. Restoration should address identified vulnerable areas, and mitigate soil erosion and runoff risk in the short term, and the recovery of nutrient cycling and keystone plant species in the longer term. We present the approach developed for assessing postfire restoration in the Mediterranean basin based on the prediction of soil-erosion risk and vegetation vulnerability.
