“…The direct association between SOM and CEC is also highlighted by the high correlation coefficient between both properties for the soils studied (Pearsonr = 0·67; data not shown). Contrarily, where SOM showed smaller differences between burned and unburned sites (B2, B4 and B5), no major changes in CEC, pH or cations were observed, as it was previously reported by Mora et al (2016) studying fire-affected pine forest form volcanic areas. However, it is also likely that these effects could have been covered up in the remaining sites (B2, B4 and B5) by hydrological and biogeochemical processes occurred in the post-fire period (8-10 months) due to the transient nature of these fire impacts (Bodì et al, 2014;Pereira et al, 2015).…”

Nutrient availability can be a limiting factor in the recovery of ecosystems after wildfire. Its evaluation is therefore critical for selecting appropriate restoration strategies in the post‐fire period. This study explores, for the first time, the use of thermogravimetry (TG) as a rapid proxy for nutrient availability and soil recovery. Soil samples from five burned and unburned sites in Andisols of Tenerife (Spain) were selected to examine the medium‐term impact of fire. Key soil chemical parameters [pH, electric conductivity, cation exchange capacity (CEC), main cation and anions in the soil solution, total organic carbon (TOC), total nitrogen (TN) and available phosphorus] were determined and thermogravimetry performed. Burned soils showed significantly higher pH, Ca2+ and Mg2+ and a lower CEC, TOC and TN than the unburned counterparts, and a site‐dependent response for soluble SO42− and available phosphorus was observed in the medium term. Time elapsed since fire could have masked additional fire impacts. Thermogravimetry data allowed reasonable prediction of most soil properties and parameters, with r2 ranging from 0·4 to 0·9. The results demonstrate that soluble nutrient content is directly related to the amount of ash in the soil. The decrease of labile carboxyl‐C was associated with an increase of pH and decrease of CEC, whereas the increase of recalcitrant and refractory pools was associated with the amount of TOC and TN. The results suggest that this novel application of an established method can provide, following an initial calibration step, rapid and inexpensive proxies for key parameters necessary for assessing fire‐induced ecosystem degradation and designing suitable restoration strategies in the post‐fire period.

“…A forest fire is any fire without control and has destructive power which occurs in vegetation, being initiated by human or natural actions (TETTO et al, 2015;EUGENIO et al, 2016;MOTA et al, 2019). These situations enhance the formation of forest fragments, the destruction of biodiversity, material goods and even human lives, increase erosion rates, soil compaction, runoff, and consequently silt up water bodies (HERAWATI et al, 2011;MORA et al, 2016;MURILLO et al, 2016;VAN ECK et al, 2016;TORRES et al, 2017a).…”

The maintenance of biodiversity is a global concern in economic, social and environmental terms. Thus, conservation units for the protection of natural environments were created. Despite the importance of these areas, forest fires have caused immeasurable and constant damage to Conservation Units. In view of this, the objective of this study was to determine the risk areas of forest fire occurrence through Fuzzy logic modeling in the Córrego Grande Biological Reserve, located in the Mata Atlântica Brazilian biome. In order to prospect for areas at risk of forest fires, the following variables were inserted in the model: land use, road network, slope and relief orientation. Finally, the model was validated by comparing the location of fire occurrences between the years 2008 and 2018, and a layout of the risk classes in the study area. In doing so, it was found that 65.87% of the area is between the 'moderate' and 'very high' range of fire risk classes, and that 70.22% of the fires which occurred in the studied period also occurred in that class range. The study concluded that the most influential variable on the risk level of fire occurrence is the forest road network. In this way, the proposed methodology can be applied to any other areas and types of land cover.

“…In Mediterranean ecosystems, due to the natural conditions (sufficient vegetation to be burned in combination with a long dry summer); and also because of human activities, fires are widespread phenomena (Pausas and Fernández-Muñoz, 2012). Recurrent forest fires induce accelerated soil erosion rates (Martínez-Murillo et al, 2016), higher runoff discharges (van Eck et al, 2016), soil properties changes (Mora et al, 2016), and plant and fauna disturbances (Végvári et al, 2016;Wang et al, 2016). To restore fire-affected land, afforestation is applied to reduce soil erosion risk during the periods that is called the post-fire window of disturbance (Moody and Martin, 2001), but also natural recovery (Keesstra, 2007) can contribute to restore the ecosystems services (Novara et al, 2016).…”

Afforestation aims to recover the vegetation cover, and restore natural ecosystems. The plant species selected for restoration will determine species richness and the fate of the ecosystem. Research focussing on the impact of vegetation recovery on soil quality are abundant, especially on fire affected land and where rehabilitation, afforestation and restoration projects were carried out. However, little is known about how different plants species affect soil erosion and water losses, which are key factors that will impact the fate of the afforested land. Aleppo pine (Pinus halepensis M.) is the species commonly used for afforestation in the Mediterranean and is very successful when natural recovery takes place, however, the original forests were composed of Holm oaks (Quercus ilex subsp. rotundifolia L.). There is little information about the hydrological and erosional impact of this change of vegetation cover stimulated by a millennia old forest use in the Mediterranean, and a century old afforestation policies and natural recovery as a consequence of land abandonment. To get insights in the effect of plant species on runoff generation and soil erosion, individual trees should be selected. Plots of 1 m 2 are necessary to identify homogeneous patches, and were installed under Aleppo pine (4 plots) and Holm oaks (4 plots) in a 30 (34)-years old plant cover recovered after a forest fire that took place in 1979. A raingauge was installed in the study site to characterize the rainfall. The soil erosion plots were built with metal borders and each plot drained to a collector (gutter) and a 60 L container to store the surface runoff. Runoff was measured after each rainfall event and sediment concentration was determined by desiccation. Results show that Aleppo pine covered soils yield six times more runoff (232 mm, 8.31%) than Holm oaks (40 mm, 1.4%) during the experimental period of 2010-2014, when rainfall amount 2,721.1 mm. Runoff sediment concentration was higher in the Aleppo pine plots (4.9 g l À1) than in the Holm oaks plots (2.6 g l À1). Soil erosion rate was ten times higher in Aleppo pine (2.6 Mg ha À1 y À1) than in Holm oaks (0.26 Mg ha À1 y À1).
