“…However, this practice does not take into consideration that controlled burns can decrease forest productivity and decrease SOM quality and quantity as shown in our modelling results. In field studies, Hatten, Zabowski, Scherer, and Dolan () also found that forest fires produced negative changes to soil properties and experimental studies of subtaiga forest‐steppe pine forests in the Southwestern Baikal Region found that surface fires were the most destructive factor in the dynamics of pine forests, drying trees, decreasing biomass and SOM pools, and lowering the nutrient status of the forest floor (Krasnoshchekov, Evdokimenko, & Cherednikova, ). The risk of losing forest‐steppe forests of the Baikal region is directly related to the intensity and frequency of surface fires (Krasnoshchekov et al, ).…”

Recurring surface fires cause soil degradation of forest land: A simulation experiment with the EFIMOD model

Renewal of pine forests is ecologically dependent on fires, but if fires become too frequent, they can disrupt the equilibrium and sustainability of these ecosystems. Field studies of the effects of fire are challenging because of the heterogeneity of forest ecosystems and because of the heterogeneous effect of fire on recovery of vegetation. As an alternative to complex field studies, mathematical models can be used as a tool to assess the complex dynamics of natural ecosystems as they recover after fire. The aim of this study was to apply the ecosystem model EFIMOD to analyse the effect of surface fires on soil degradation and its feedback on tree productivity in Scots pine forests on different soil types in Russia: Haplic Podzols in the Leningrad region and Psamment Entisols of the fragmented steppe in the Samara region. Simulation of the cumulative effects of fire cycles over 140 years showed that one fire did not affect growing stock but decreased soil organic matter by about 10% at both sites, and that three fires reduced the growing stock by 30% on the Haplic Podzols and 9% on the Psamment Entisols and decreased soil organic matter by about 30% on both sites. Forest fires led to the loss of soil carbon (C), as well as nitrogen (N), which is a principal limiting factor in forest ecosystems of boreal and temperate ecozones. The effect of repeated fire cycles on land degradation is similar to that of soil erosion, through the loss of soil C and N.

“…The more significant losses of K and P on the burned sites Fb and Cb compared to the unburned clear-cutting C confirm the primary influence of fire on reducing the accumulation of these biogenic elements in the disturbed litters and enhancing their leaching and washing out from the upper soil horizons under the humid conditions of the mountain microclimate and flushing soil regime [43,[49][50][51]. Post-fire alkalinization of soil solutions, coupled with an increase in the ash content, further enhances the mobility and migration of K, P, and N and most cations downward through the soil profile [48,52].…”

The well-known phenomenon of attracting untypical animals to disturbed territories has been poorly investigated in the polar mountains. We studied arthropod diversity in self-healing industrial clear-cuts and burn areas in the Khibiny Mountains, Kola Polar region. Fieldworks were conducted at four sites, including a control mountain taiga forest and its three transformed variants: burnt forest, uncleared clear-cut, and twice-disturbed burnt clear-cut. Arthropods were collected using formalin traps 2–3, 5–6, and 8–9 years after industrial deforestation in 2012 and an extensive grass-roots fire in 2013. Out of 124 identified species (spiders—61; ground beetles—41; and rove beetles—22), 79 (or 64%) were collected in disturbed, primarily burned areas and were absent in control forest. We note ten species of rove beetles, nine species of ground beetles, and eight species of spiders for the first time in the well-studied arthropod fauna of the Khibiny Mts. We found that grass-root fires transform the soil vegetation covers in the polar mountain forests more powerfully in comparison with extensive deforestation and attract a greater diversity of arthropods with different preferences, enriching the fauna of the polar mountains and the Subarctic region as a whole. The attraction effect persists for, at least, a decade after the violations.
