“…The species composition of the understorey probably also reflects fires as a controlling process. The studied forest includes species, such as Arctostaphyllos uva-ursi, Avenella flexuosa, Brachypodium pinnatum, Calluna vulgaris, Carex macroura, Chimaphila umbellata, Pteridium aquilinum, Pulsatilla patens, P. vernalis, Trientalis europaea, Vaccinium myrtillus and V. vitis-idaea, which are typical for post-fire succession in boreal forests in Northern Europe (Ruokolainen and Salo, 2006) or Western Siberia (Krasnoshchekov et al, 2010;Lytkina and Mironova, 2009) owing to their easy vegetative or generative post-fire re-establishment (Kalamees et al, 2005;Moog et al, 2002;Rowe, 1983;Schimmel and Granström, 1996;Uotila, 2005). Other fire indicators Geranium bohemicum and Tephroseris palustris (Esseen et al, 1997;Granström, 1993;Lytkina and Mironova, 2009) are extremely rare species (Holub and Procházka, 2000), which formerly also occurred in study area (Kochjarová and Hrouda, 2004;Slavík, 1997).…”

Unusual vegetation stability in a lowland pine forest area (Doksy region, Czech Republic)

Although the Holocene is characterized by prominent vegetation changes, some vegetation types can reveal surprising stability. We studied Holocene woodland history in a sandstone pseudokarst area (Doksy region, Northern Bohemia, Czech Republic). Twelve soil profiles collected under native or semi-cultural pine forests were analyzed using anthracological methods. In seven of them, the age of profile bases was established using radiocarbon dating. All analyzed samples show a high degree of mutual similarity of species composition regardless of the site or the depth of the sampled soil layer, as well as a good concordance between the composition of fossil and contemporary vegetation. Forest vegetation dominated by Pinus sylvestris with a low but regular occurrence of Picea abies, Quercus sp. and Vaccinium sp. has prevailed since late Boreal up to the present. No considerable vegetation changes were detected during this period, except for succession after fire events. A high content of charcoal within soil profiles indicates that the study area has been affected by forest fires through a substantial part of the Holocene. Recurrent wildfires probably represented a crucial factor sustaining pine forests by cyclic succession, although the relative contribution of human versus natural causes of fire cannot be assessed. In earlier phases of the Holocene, the prevalence of pine in the local vegetation was revealed using palynological data, so that we can conclude that the pine-dominated forests ecosystem existed during the entire Holocene in the study area. This pronounced vegetation stability contrasts sharply with the changeable historical vegetation of Central European lowlands.

“…The pyrogenic impact is one of the most considerable factors in the dynamics of biogenic landscape components. Secondary post-fire forests occupy a wide area in the south of Eastern Siberia (Chernykh & Zolotov, 2006;Krasnoshchekov et al, 2010;Sukhomlinov, 2012). The damage degree ranges from 30% to 85% in the forested area of the Siberian taiga (Dorzhiev et al, 2017).…”

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.
