“…Therefore, the local population sought to create nut (seed) orchards with a predominance of Siberian pine near their villages (Debkov, 2014). As a rule, Siberian pine trees were left during felling, while the remaining tree species were cut down, resulting in the formation of Siberian pine seed orchards (Debkov, 2019).…”

The article considers the long-term (100 years) dynamics of the forest cover of the southernmost unit of Siberian pine forests on the West Siberian plain. A key feature of forest management is that Siberian pine seeds are a valuable food product and, when cutting forests, this tree species, as a rule, is preserved. The basis of the experimental data was the material of the national forest inventories of 1915, 1974 and 2015 for a total area of 1,420.41 ha. During the period from 1915 to 2015, the forested area changed slightly (96.2 and 94.0%), while the share of Siberian pine stands increased significantly from 48.4 to 58.7%. Grassy Siberian pine forests (32.1%) of optimal age (120–140 years), which are characterised by the best seed productivity and the largest share of Siberian pine in the community (77%), predominate. Basically, human economic activity results in an increase in the area of Siberian pine stands, when deciduous stands with Siberian pine undergrowth are used for fuel and as building material. A decrease in the area of Siberian pine forests occurs mainly under the impact of fires. In the conflagrations of 1915–1920, 7 to 38% of silver birch forests have no Siberian pine undergrowth and are considered long-term secondary communities. In the remaining area, the proportion of Siberian pine undergrowth is 20–30% with a density of 800–1200 seedlings ha−1, which is sufficient for the natural formation of Siberian pine forests.

“…The species` distribution range stretches from the western Urals through the West Siberian Plain to the Transbaikalia (the Baikal Lake region) and southern Sakha-Yakutia and from the Arctic Circle to northern Mongolia (Titov, 2007;Shuvaev and Ibe, 2021). Forests with a predominance of Siberian stone pine cover an area of about 40 million ha (Debkov, 2019). Siberian stone pine is a monoecious, wind-pollinated and zoochoric tree species (Gribkov, 2014).…”

Genetic diversity and structure of Siberian Stone Pine (Pinus sibirica Du Tour) populations

et al. 2023

Siberian stone pine (Pinus sibirica Du Tour) is a key component of the Eurasian boreal forest ecosystems. However, due to the ongoing climatic changes and anthropogenic activities, the habitats of the species are constantly degrading and reducing. To these reasons, exploring the genetic resources of the species and determining the genetic diversity and structure of today’s populations is essential. In this study, we assessed genetic diversity and differentiation in six Siberian stone pine populations from different forest zones in Middle Siberia. Based on seven microsatellite nuclear markers (nSSR), moderate level of genetic diversity (He=0.455) was detected. A population structure analysis divided the six Siberian stone pine populations into two groups. Southernmost populations were distinguished from the others. Analysis of molecular variance (AMOVA) showed that only 2 % of the genetic variation occurred among populations. Our findings suggest that extensive gene flow may prevent genetic differentiation among Siberian stone pine populations. Hence, further genetic diversity estimation with additional loci is needed for crucial insight into the gene pool of Siberian stone pine populations.

Selection of high-yielding samples of Siberian stone pine in artificial plantations created outside its habitat potentially improves the quality of work on its introduction. The study represents an assessment of the level of individual variability of Siberian stone pine by seed yield in the context of introduction (taking into account its variation by years of crop generation). Studies were conducted in the annually seeding Chagrinsky cedar grove located in the Gryazovetsky District of the Vologda Region. Sample trees were selected to observe the dynamics of seed formation in the plantation. Observations allowed us to conclude about the irregularity of yields from year to year and high variability in the volume of yields among individual trees. A significantly pronounced effect on the seed yield of Siberian stone pine is recorded both in terms of the year of cone generation and individual variability of the trees. Individual characteristics account for 41% of the total variation in yield, while the year of observation accounts for only 21%. Dependence on individual variability slightly decreases with the increasing duration of observations, which may be due to chronographic variability in the reproductive capacity of the trees. It was concluded that the selection of maternal producers for the creation of high-yielding plantations is advisable. At the same time, the increased observation period for the reproductive capacity of individual trees makes it possible to increase the efficiency of selection. To reduce the duration of observations, it was recommended to use the ratio of crown width to crown length as a correlative feature. Nevertheless, in some non-yielding years, the relationship between the yield and this feature may not be evident. For this purpose, the trees with the lowest value of this indicator should be selected as high-yielding ones.
