“…The restoration of indigenous plant communities occurs from the age of 20-25 years, which generally confirms the general trend of successional series in the cryolithozone of Central Yakutia [8][9][10]. Restoration of ground moss-lichen and lichen cover in such conditions requires considerable time and occurs only on poor gravelly and sandy loam soils.…”

“…The value of the pyrogenic factor in the forest formation process increased in the second half of the XX century due to a sharp increase in the share of anthropogenic fires [3,4]. Note that in Central Yakutia, as in other regions, the main cause of fires is the human factor [5]. The role of fires in forest life is far from ambiguous in its consequences and ecological content [6].…”

“…On the one hand, fire in the forest is a destructive factor of destructive power, which acquires the character of ecological catastrophes in certain periods, and leads to partial or complete destabilization of the forest ecosystem. On the other hand, forest fires have a positive impact on the condition and development of forest stands, acting as a factor of renewal in the ecosystem and contributing to the natural renewal of tree species [7][8][9][10]. This is especially true for forest formations that are formed by tree species with a pyrogenic life strategy.…”

Changes in the ground environment under the influence of fires in the territory of the State Natural Reserve «Olekminsky»

This paper discusses the chronology and cause of forest fires on the territory of the State Reserve “Olekminsky”. Forest fires on the territory of the reserve are low-level, caused by dry thunderstorms. The overgrowth of burnt areas occurs at the expense of specific groups of pyrophyte plants. For 2-3 years after the fires, Camenerion angustifolium (L.) Scop., Corydalis sibirica (L.) Pers., Plantago canescens Adams, Crepis tectorum L. and others were found. In waterlogged areas, Tephroseris palustris (L.) Reichenb appear and subsequently do not occur, and mosses: Marshantia polymorpha L., Ceratodon purpureum (Hedw.) Brid. It was found that the restoration of ground cover is mainly due to species characteristic only for intermediate stages: Lichens - Baeomyces carneus, Dibaeis baeomyces and Trapeliopsis granulosa, as well as Arctous erythrocarpa (Small) M. Ivanova, Chamaenerion angustifolium (L.) Scop., Calamagrostis obtusata Trin, Сarex spp., cereals and green mosses. More than 40 species of lichens participate in the formation of the ground cover of the studied larch forests, mainly bushy species of Cladonia, Stereocaulon, Peltigera. Forest fires of a natural nature occurring on the territory of the reserve are the main limiting factor affecting bio-resources and theirrestoration.

“…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). The survival of these species can be facilitated also by forest thinning, pasturing and especially by litter raking.…”

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

2012

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.

“…There are significant differences between succession stages separated from each other by large time intervals (Table 3). This contrast of the species composition on multiple-aged burned sites was identified in the study of post-fire succession of larch forests (Lytkina and Mironova, 2009).…”

a r t i c l e i n f o a b s t r a c t Available online xxxxThe characteristics of four stages of demutational succession of a valley Korean pine-broadleaf forest are provided according to the parameters most vividly capturing the structure of the plant community and influencing the renewal and mycorrhization of Korean pine (Pinus koraiensis) seedlings. It was found that Korean pine seedlings grow in a competitive environment on the fresh burned site; hence the mycorrhization occurs from specialized symbiotes that provide competitive advantages and adaptation to stress factors. Mycorrhiza forms the least successful in the 50-60-year-old larch-birch-spiraea association during the seral stages of succession.The 90-100-year-old birch-broadleaf association offers the most suitable soil and cenotic conditions for the development of Korean pine seedlings that can successfully generate mycorrhiza from both the spores present in the thick soil layer, and through mycelia of shared mycorrhizal networks of seral and primary (including Korean pine) tree species. A 230-250-year-old climax community comprises all patterns to ensure that pine seedlings encounter a fungal component; in this community the greatest abundance of species and a balanced composition of ectomycorrhizal fungi communities of Korean pine are observed. IntroductionThe increase of the number and the area of fires, both of man-made and natural origin, on the territory of one of the richest forest regions of Russia -the Far East leads to a sharp reduction of valuable forest ecosystems, including primary pine-broadleaf forests (Astafiev et al., 2004;Sukhomlinov, 2006; Petropavlovsky and Astafiev, 2010). Natural regeneration of pine forests after the fires is a complex, lengthy and understudied process. So far data was obtained on demutational successions in pine forests after the fires, mainly concerning the changes in the composition and structure of communities, the early stages of succession, soil banks of seeds and morphogenesis of species (Kolesnikov
