“…Depending on fire severity, wildfires modify the physical, chemical and hydrological soil properties (Shakesby & Doerr, 2006;Shakesby, 2011;Robichaud et al, 2013;Malvar et al, 2016a). Soil surface conditions also change, and runoff and erosion processes are enhanced, especially when ash cover is completely removed (Bodí et al, 2012;Martínez-Murillo et al, 2016a). The post-fire spatial distribution of soils and vegetation patterns plays an important role from the hydro-geomorphic point of view.…”

This study assessed the effect of a wildfire and different post‐fire practices (salvage logging, skid trails and check dams) and vegetation recovery (eight scenarios) on the hydrological connectivity (HC) in 11 sub‐catchments (SubCs; 330 ha) affected by a wildfire (213 ha) in 2012 in Spain. According to the Landsat 8 Operational Land Imager/Thermal Infrared Sensor images, moderate, high and extreme burn severity affected 42·1% of the area. HC was calculated with an updated version of the Borselli index. Within the burned area (BA), HC increased in all SubCs after the wildfire (PostF‐1), the salvage logging and the new skid trails (PostF‐2), and the development of new gullies (PostF‐3). Check dams reduced connectivity but did not prevent the general trend. Afterwards, the incipient (PostF‐4 and PostF‐5) and future vegetation recovery made slightly decrease HC. In the three forestry SubCs with check dams and large BA (67% of the study area), connectivity markedly increased (11·4%, 18·2% and 22·9%) during the three first post‐fire scenarios. In the three SubCs with urban areas and small BA (5%), HC decreased a little because the linear elements connected the hillslopes between them. In the three SubCs with urban areas and large BA (12%), HC increased less than in the forestry SubCs (3·0%, 8·2% and 9·1%). In the two forestry SubCs without check dams and small BA (16%), the increment of connectivity was low (2·5%, 4·6% and 6·3%). Monitoring of check‐dam siltation and of the actual vegetation regrowth is necessary to minimize the off‐site consequences of high HC. Copyright © 2017 John Wiley & Sons, Ltd.

“…Although it is known that fungi are more resistant to temperature changes than bacteria (Bárcenas-Moreno et al, 2011), the survival of fungi and bacteria in different environments has not been deeply evaluated. However, stronger activity of these microorganisms has been found after fires (Bodí et al, 2012).…”

“…As a component of the earth system, fire has influenced the composition of atmospheric gases, climate, biota, geoformations, transportation of materials and sedimentation rates (Fernández and Vega-Hidalgo, 2011;Bodí et al, 2012). Recurrent fires favor a different ecosystem than would be expected based on climate, and species with some fire resistance mechanism persist and develop their own survival strategies (Pausas et al, 2008).…”

Influence of fire on soil and vegetation properties in two contrasting forest sites in Central México. Cien. Inv. Agr. 45(2): 128-137. Fire produces changes in vegetation, soil, fauna, and water quality, and it can even modify atmospheric chemical composition. Changes in soil fertility, microorganisms and vegetation were evaluated after a fire in two municipalities in the State of Hidalgo, Mexico. Inside and outside the burned area, four 100 m 2 plots were established. In each of the eight plots, soil samples were collected at two depths (0-5 and 5-20 cm) in the following areas: non-burned area (NBA); 15 days after fire (15DAF); and 12 and 24 months after the fire (MAF). Vegetation quantification was carried out at 30, 180 and 540 DAF. The results at 15DAF showed an increase of alkaline and metallic elements as well as pH in the surface layer, and this trend remained the same to 12MAF. There was greater Fe, Mn and Zn content in Zacualtipán and greater K, Ca, Mg and P in Singuilucan. At 24MAF, due to the nutrient requirements of the herbaceous and scrub growth, this effect was reverted. The fire reduced the organic matter (OM) and total nitrogen (TN) contents, without any recovery during the evaluated period. Bacteria showed greater mortality because of the fire: 76% and 50% at the Zacualtipán and Singuilucan sites, respectively. The canopy opening promoted a 50% increase of species in Zacualtipán. In conclusion, the fire temporarily increased soil fertility and the presence of herbaceous vegetation, but it reduced the bacteria and fungi populations.

“…This increment is commonly due to a decreasing of total rainfall and an increasing of temperature over recent decades (Stott et al, 2004;Harding et al, 2009). However, human influences, including land use change brought about by widespread socio-economic change and urban expansion, have been viewed as the main drivers of the dramatic increase in wildfire activity (Pausas et al, 2008;Shakesby, 2011;Bodí et al, 2012;Carreiras et al, 2014;Pereira et al, 2015). One of the ways in reducing wildfire hazard is prescribed fires to reduce fuel in forests and rangelands, but the little-known effects of such prescribed burnings on entire ecosystems induced debate and research activities in various disciplines.…”

“…However, once the ash is removed or crusted into the soil surface due to its mobilization by rainwater drops, there is a remarkable increase in runoff, especially when the soil is water repellent. In turn, soil erosion tends to be reduced due to the recovery of vegetation cover in time (Bodí et al, 2012). In Mediterranean conditions, runoff rate and soil erosion magnitudes are highly variable and erosion rates were generally less than 1 tn ha À1 per year (Cerdà & Bodí, 2007).…”

Short‐term Experimental Fire Effects in Soil and Water Losses in Southern of Spain

et al. 2016

This study deals with the experimental fire effects in overland flow and soil erosion at plot scale and considering rainfall erosivity. The study was conducted in from May 2011 to Dec 2013. Six plots of 12‐m length and 2‐m width are considered: four of them were burned, whilst two of them remained in natural conditions. Overland flow was collected in deposits of 250 L after each rainfall event, measured at a meteorological station. Larger rainfall intensities and erosivity were registered after summer and, thus, overland flow and sediment yield, but one order of magnitude higher in the burned plots than in the unburned ones. Especially, the difference in overland flow and soil loss between both set of plots were nearly three folds larger whether the rainfall intensity exceeded 30 mm h−1 during 15‐min intensity. It is remarkable that the most erosive event generating the maximum values of overland flow and soil loss was registered 16 months after the experimental fire when a rainfall event of 99·2 mm h−1 occurred. This delay is considered as consequence of soil surface conditions and ash cover. Copyright © 2016 John Wiley & Sons, Ltd.
