“…Fire has an important presence and influence in these Mediterranean ecosystems, its damage mostly depends on fire intensity and frequency. The reconstruction of vegetation is slow, and repetitive fire events may seriously endanger revegetation (Francis and Thornes 1990;Ferran et al 1992;Bautista et al 1994;Moench and Fusaro 2003).…”

Abstract. In the Mediterranean basin, fires are a major concern for forest and shrubland ecosystems. We studied flammability, its seasonality and its relationship with leaf moisture and volatile terpene content and emission in the dominant species of a Mediterranean shrubland and forest in Catalonia (NE Iberian Peninsula). We measured temperatures and time elapsed between the three flammability phases: smoke, pyrolysis and flame, for four seasons. We sampled twice in spring because of an occasional drought period during this season. Flammability had a significant relationship with leaf hydration, in the shrubland and in the forest. Few and only weak correlations were found between terpene content and flammability. In the future, arid conditions projected by climatic and ecophysiological models will increase fire risk through decreased hydration and subsequent increased flammability of the species.

“…Se ha evaluado la velocidad teórica de regeneración de cada tesela en función de las especies presentes; para ello, se ha asignado la estrategia reproductiva a cada una de las cuatro posibles especies (o formaciones vegetales) principales. Para cada tesela, la valoración se ha establecido atendiendo al porcentaje de superficie ocupada por especies rebrotadoras, ya que éstas presentan un rápido recubrimiento del suelo poco después del incendio (Ferran et al 1992;Abad et al, 1997;Vallejo & Alloza, 1998;Pausas & Vallejo, 1999). Las categorías establecidas han sido: Alta: Presencia de especies rebrotadoras en un mínimo del 40% de la superficie de la tesela.…”

Wildfires may produce ecosystem damages that would require post-fire mitigation and/or restoration actions. The question is what are the criteria to identify those burned areas that show high degradation risk in order to plan and prioritise restoration projects. To address that question it is necessary to start with the analysis of fire impact, and from that analysis to derive predictive tools for assessing the fragility and regeneration capacity of burned ecosystems. The identification of post-fire degradation mechanisms provides the basis for developing the corresponding specific mitigation/restoration actions. The diagnostic of ecological impact of wildfires together with the established forest management objectives allow deriving mitigation/restoration strategies and the subsequent implementation projects.We present our experience on the evaluation of post-fire ecosystem vulnerability and on the assessment of restoration planning derived from recent and ongoing EC research projects. This includes the development of short-term restoration techniques suited for degraded soils and dry Mediterranean conditions, where fire-induced degradation is complicated with water shortage for regenerating vegetation.

“…Furthermore, the soil is unprotected from rainfall impact, changing soil infiltration rates and consequently increasing erosion risk (Francis and Thornes, 1990;Bautista et al, 1994;Moench and Fusaro, 2003). Accelerated soil erosion decreases regeneration possibilities for different vegetation species (Ferran et al, 1992b).…”

Inventories of vegetation were collected in a burnt area located in Cadiretes massif, Catalan Coastal Ranges, northeast Spain. The burnt forest primarily consisted of pine plantation (Pinus pinaster) with a large number of cork trees (Quercus suber). The burnt area was divided into three zones based on fire intensity. Data from three different periods after the fire (six, ten and twenty-four months) showed differences between the recovering vegetation and that in a control forest area. Numbers and types of resurgent vegetation species following the fire were different in each area. Regeneration of vegetation is important not only in terms of plant regrowth but also for protecting the soil surface from rainfall impact. During the research period the burnt area was managed homogeneously by the forestry authorities. Management operations, among others, involved tree felling, construction of terraces, with dead trees to control erosion, and reforestation of some species. Some of these operations, such as tree felling and the creation of terraces which were carried out one year after the fire, were implemented too late, since the most serious erosion had already taken place. Some operations, such as reforestation in some low intensity burnt areas, are unnecessary due to the profuse recovery of Pinus and Quercus suber.
