“…Different groups of microorganisms show different strategies against disturbances. Fungi, for example, often show greater resistance than bacteria (Dunn et al, 1985), although bacteria can recover faster (Guerrero et al, 2000;Guerrero et al, 2005;Bárcenas-Moreno and Baath, 2009;Ponder et al, 2009;Bárcenas-Moreno et al, 2011). However, if fire intensity is sufficiently high, soil may become partially sterilized (Pietikäinen and Fritze, 1995).…”

ABSTRACT.Wildfires may produce several changes in the short-and longterm in the landscape and in the soil system. The magnitude of these changes induced by fire in the components of ecosystems (water, soil, vegetation and fauna) depends on fire properties (fire intensity and severity) and environmental factors (vegetation, soil, geomorphology, etc.) Cómo afectan los incendios a las propiedades del suelo. Una breve revisión (vegetación, suelos, geomorfología, etc.) RESUMEN. Los incendios forestales pueden producir varios cambios a corto y largo plazo en el paisaje y en el sistema suelo. La magnitud de estos cambios inducidos por el fuego en los componentes de los ecosistemas (agua, suelo, vegetación y fauna) depende de las propiedades del incendio (intensidad y severidad del fuego) y ambientales

“…Boron concentration did not differ between unburned and burned soil and was 20-fold higher in ashes, but the only published reference we found reported higher levels of extractable B in burned forest soils than in unburned ones (Ponder et al 2009). The wide difference between extractable B concentration in ashes and sediments from the first erosion event could be due either to high losses in soluble form, as this element is quickly leached from ashes (Khanna et al 1994) or to a preferential erosion of ash or soil particles impoverished in B.…”

“…Although Pivello et al (2010) found a negative correlation between pH and Mn in burned soils, we found a positive correlation (r ¼ 0.633; P , 0.001) between pH KCl and extractable Mn. It has been reported that 1 year after a prescribed fire there is no difference in extractable Mn between unburned and burned soils (García-Marco and González-Prieto 2008;Ponder et al 2009). In the same way, we found that the extractable Mn concentration in sediments, unaffected by the emergency stabilisation treatments, decreased steadily with time, indicating that Mn is easily lost; however, 1 year after the fire, the sediments were still notably enriched in Mn compared with the burned topsoil.…”

Abstract. The effect of two post-fire stabilisation techniques (Seeding and Mulching) on trace element (Al, B, Co, Cu, Fe, Mn, Mo and Zn) losses with eroded sediments was evaluated over a 13-month period following an experimental fire in a steep shrubland of a temperate-humid region (north-west Spain). With time, concentration of extractable Mn, Zn and Cu in sediments decreased, Fe tended to increase and Al, Co, B and Mo varied without a clear trend. Most sediments and trace element losses occurred during the first 3 months post-fire. Compared with the available elements in ash þ burned topsoil, the fraction lost with sediments was highest for Mo (10-16%), intermediate for Mn (4%) and Zn (3%) and low for the rest (0.4-1.2%). Although minor effects of stabilisation techniques on element concentrations were found, accumulated mass losses of trace elements decreased 6-12 times in Mulching because of its 10-fold lower soil erosion rate; no significant changes were found in Seeding. Sediment nutrient losses are probably more important than those published for smoke, leaching or volatilisation. Our results suggest that the Zn and Cu enrichment in sediments from the first erosion events increase the risk of downslope water and soil contamination. In conclusion, soil stabilisation techniques are useful to prevent post-fire ecosystem damage.

Abstract. Prescribed burning is a forest management practice that is widely used in Australia to reduce the risk of damaging wildfires. Prescribed burning can affect both carbon (C) and nitrogen (N) cycling in the forest and thereby influence the soil-atmosphere exchange of major greenhouse gases, i.e. carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O). To quantify the impact of a prescribed burning (conducted on 27 May 2014) on greenhouse gas exchange and the potential controlling mechanisms, we carried out a series of field measurements before (August 2013) and after (August 2014 and November 2014) the fire. Gas exchange rates were determined in four replicate plots which were burned during the combustion and in another four adjacent unburned plots located in green islands, using a set of static chambers. Surface soil properties including temperature, pH, moisture, soil C and N pools were also determined either by in situ measurement or by analysing surface 10 cm soil samples. All of the chamber measurements indicated a net sink of atmospheric CH 4 , with mean CH 4 uptake ranging from 1.15 to 1.99 mg m −2 d −1 . Prescribed burning significantly enhanced CH 4 uptake as indicated by the significant higher CH 4 uptake rates in the burned plots measured in August 2014. In the following 3 months, the CH 4 uptake rate was recovered to the pre-burning level. Mean CO 2 emission from the forest soils ranged from 2721.76 to 7113.49 mg m −2 d −1 . The effect of prescribed burning on CO 2 emission was limited within the first 3 months, as no significant difference was observed between the burned and the adjacent unburned plots in both August and November 2014. The CO 2 emissions showed more seasonal variations, rather than the effects of prescribed burning. The N 2 O emission in the plots was quite low, and no significant impact of prescribed burning was observed. The changes in understory plants and litter layers, surface soil temperature, C and N substrate availability and microbial activities, following the prescribed burning, were the factors that controlled the greenhouse gas exchanges. Our results suggested that the low-intensity prescribed burning would decrease soil CO 2 emission and increase CH 4 uptake, but this effect would be present within a relatively short period. Only slight changes in the surface soil properties during the combustion and very limited impacts of prescribed burning on the mineral soils supported the rapid recovery of the greenhouse gas exchange rates.
