“…Thermally altered reddened soil surfaces are common in Mediterranean-type climate regions after forest fires in places where logs have combusted on the ground surface (Ulery and Graham 1993, Shank 2004, Goforth et al 2005, Ulery et al 2017. Intense burns consume organic matter that binds soil particles into aggregates potentially leading to loss of soil structure, increased bulk density and reduced soil porosity (Neary et al 1999, Hubbert et al 2006).…”

“…Within stands of high mortality the extent of extreme soil burning from down wood is localized and red soil conditions may be of minor consequence because of their typical infrequence (Goforth et al 2005, Ulery et al 2017. Within most of the B&B Fire perimeter, red soils occupied ≤6% of the land surface (Shank 2004).…”

Fire may remove or create dead wood aboveground, but it is less clear how high severity burning of soils affects belowground microbial communities and soil processes, and for how long. In this study, we investigated soil fungal and bacterial communities and biogeochemical responses of severely burned "red" soil and less severely burned "black" soil from a burned forest on the eastern slope of the Cascade Range in Oregon. Specifically, we examined the effects of burn severity on soil nutrients and microbial communities for 1-4 years after wildfire. Soil nutrients were significantly reduced in red soils. Soil fungi and bacteria, assessed with molecular methods, steadily colonized both burn severities and soil biodiversity increased throughout the study showing that microbial communities seem to have the capacity to quickly adjust to extreme disturbances. Although richness did not vary by soil type, the fungal and bacterial community compositions varied with burn severity. This difference was greatest in the early time points following the fire and decreased with time. However, nutrient-limited conditions of red soils were detected for four years after the wildfire and raise concern about soil productivity at these sites.

“…In a study conducted in the Mediterranean, Keesstra et al () verified that soil–water repellency due to burning could contribute to soil degradation processes, reducing the maintenance of soil moisture and soil fertility and increasing soil and water losses. In California, Ulery, Graham, Goforth, and Hubbert () found that fires, besides increasing the surface temperature, can alter the properties of the soil and some minerals.…”

Fire outbreaks in extreme climate years in the State of Rio de Janeiro, Brazil

Plant burning in tropical countries is a threat to the environment. It not only damages the local ecology but also affects the economy and society. This work aimed to analyze the meteorological systems, soil attributes, and meteorological variables derived from NCEP-DOE Reanalysis 2 for 3 years of atypical climatic events (2005, 2010, and 2015); and relate these factors to the occurrence of fire outbreaks in the State of Rio de Janeiro, Brazil. In 2005, a total of 1,085 fire outbreaks were registered in the State, and most of them occurred during the dry season in the soil classes ultisol (542) and oxisol (139). The highest fire outbreaks concentration was reported in 2010, totaling 1, 702 outbreaks, and Argissolo and Latossolo (747 and 301, respectively) were also the most predominant soil classes. This fact can be explained by the greater predominance of pastures and greater area in km 2 in the State. In 2015, the highest number of fire outbreaks was recorded, again, in Argissolo (418), in addition to Gleissolo (102). The total number of fire outbreaks registered in 2015 was lower than those recorded in 2005 and 2010, totaling 916 fire outbreaks statewide. The correlation shows maximum positive values of zonal wind component (0.71) for 2005. The highest negative values correlations found for 2005, 2010, and 2015 were for the meteorological traits soil moisture and relative air humidity, respectively. The present study is important for highlighting up the vulnerability of the Atlantic Forest ecosystem, given the occurrence of fire outbreaks.

“…SOM is of vital importance for nutrient cycling and cation exchange because nutrients 435 can be volatilized or transformed into available forms via the combustion of SOM 436 (Knoepp et al, 2005). Moreover, SOM, as well as the clay type and content determine 437 the CEC (Ulery et al, 2017). Prescribed burnings are characterized by low intensities; 438 therefore, the temperatures that are reached could be sufficient to produce the 439 combustion of a part of the SOM but lower than the temperatures necessary to induce 440 mineral alterations (Bodí et al, 2014).…”

The abandonment of the traditional pastoral activities in the subalpine grasslands of the Central Pyrenees (NE-Spain) has resulted in shrub encroachment processes that are dominated by species such as the Echinospartum horridum. Therefore, prescribed burning has been recently readopted in this region as a management tool to stop the spread of shrubs and recover grasslands. We aimed to assess the effect that this practice may have on soil chemical properties such as SOC, N, pH, EC, water-extractable and exchangeable cations (Ca, Mg and K), cation exchange capacity, inorganic N forms (N-NH and N-NO) and available P. We studied two prescribed burnings conducted at the subalpine level of the Central Pyrenees in the municipalities of Tella-Sin (April 2015) and Buisán (November 2015). At each site, the topsoil was sampled in triplicate at soil depths of 0-1, 1-2 and 2-3 cm immediately before (U), immediately after (B0) and one year after (B12) burning, and litter and/or ashes were removed prior to sampling. The results indicate that in the B0 samples, burning significantly reduced the SOC and N contents as well as the exchangeable Ca and Mg at 0-1 cm, whereas the rest of the studied properties remained virtually unchanged. However, in the B12 samples we detected a decrease of nutrient content that was probably related to leaching and/or erosion processes.
