“…At present the vegetation recovery process conditions in this plot are equal to those at other tested pine forests (Pn26, Pn38) of Group III at fi rst year of study. All these facts are the confi rmation of the longest period of re-vegetation in fi re-damaged lichen pine forests which are self-perpetuating in absence of fi re (Kovaleva, 2014;Morneau & Payette, 1989). Among established plots that have not been observed during all study period, Pn29 can be classifi ed to Group II (together with Pn28 and Bt30) on the base of detrened correspondence analysis (DCA) of environmental factors.…”

Wildfire is regarded as important environmental factor determining the vegetation of the Earth. We analyzed 11 plots at different types of forest affected by fire at the southern boundary of the taiga zone. These differ in structure of the forest stand and herb-shrub layer. Investigated factors included edaphic (moisture, pH, nitrogen) and climatic (light, temperature, continentality) characteristics. Also, projective cover of Epilobium angustifolium L. and undergrowth of secondary growth trees (including forest stand survived after fire influence) were studied. Multivariate data analysis revealed that the rate and character of the vegetation recovery was depended on the ratio of environmental factors and on the species composition of herb-shrub layer. No significant differences were found in Ellenberg’s indicator values between different years of study. All tested forest habitats were distinguished into three main groups: Group I includes broadleaf forests with the forest stand survived after fire influence, Group II includes spruce and birch forests deprived the forest stand due to fire impact, Group III includes more or less dry pine-dominated forests with the forest stand gradually died after fire influence. Two marshy plots have prerequisites to their allocation to a separate group close to the oligotrophic bog forests.

“…The degree of the wildfire damage explains a series of stages in derivative associations of the subshrub and herb layers (Groot et al, 2004;Kovaleva et al, 2012;Roberts et al, 2019). The fireweed-reed-grass post-pyrogenic stage of the vegetation development often observed in fire-damaged areas under similar environmental conditions has been recorded five years after the wildfire on site B with a strong degree of the wildfire effect (Kovaleva et al, 2012;Gongalsky, 2015). Green mosses and subshrubs were not recorded.…”

“…plants did not contribute to the active growth of pine seedlings either, due to the high shading and competition for moisture and nutrients. In this connection, the managed burning treatment is favourable for an effective way to promote post-fire pine regeneration, besides of weeding and loosening (Belov, 1973;Kovaleva et al, 2012;Matveev & Matveeva, 2017). The spring grass fire, recorded in 2018 on site A, did not have negative consequences in the development of vegetation renewal, but it contributed to the thinning of plant communities.…”

A morphological variety of pyrogenic transformations characterises burnt areas of the Badary area of the Tunkinskiy National Park (Russia), from heavily damaged areas with a partially remained forest stand to bare spaces of tens of square metres. This enabled us to study the dynamics of the post-fire reproduction of Pinus sylvestris (hereinafter – pine) forests in areas with various environmental conditions. The main goal of our study was to determine the nature of the pyrogenic transformation of ecosystems and to evaluate the success of the forest reproduction. The studies were based on the geobotanical monitoring in two burnt-out areas, differing in the degree and area of wildfire damage due to a creeping fire in 2010. Between 2014 and 2020, we considered the multi-temporal specificity of the species composition of the forest stand, shrub layer, and plant communities. The emergence of the first shoots of undergrowth and new growth has been recorded. The projective cover and the dynamics of the species abundance in all forest layers were fixed. The analysis of the natural reforestation dynamics revealed a similarity of the main geobotanical indicators. Pine seedlings dominated in the undergrowth of the study sites, with a small proportion of Betula pendula. The shrub layer consisted of Rosa acicularis. Rhododendron dauricum has been found there only at the late stage of the study. In the herbaceous layer, the largest proportion was represented by meadow species, with a small participation of forest plants. Differences were revealed during the emergence of first seedlings of undergrowth and new growth, as well as in the size of projective cover of species in all forest layers. The first pine seedlings on a heavily burnt-out study plot were recorded a year earlier than on a less transformed plot. Nevertheless, the height increment and the projective cover of the undergrowth were significantly higher on the burnt-out area of a medium damage degree. On the heavily fire-damaged area, we observed pine seedlings planted by the staff of the Tunkinskiy National Park. A satisfactory rate of seedling survival at the initial stage and further deceleration of growth parameters have been noted. The obtained results indicate the reforestation success and, therefore, a favourable forecast of post-fire recovery of light-coniferous forests in the Badary area of the Tunkinskiy National Park.
