Middle Siberia

The study was carried out in four forest nurseries of Middle Siberia. Affected seedlings of Scots pine (Pinus sylvestris L.), Scots Siberian stone pine (Pinus sibirica Du Tour), and Siberian spruce (Picea obovata Ledeb.) were collected for molecular phytopathological examination. In total, 14 fungal taxa were identified in the needles and roots of the plants. The most dominant among them were Sydowia polyspora (Bref. & Tavel) E., Didymella glomerata (Corda) Qian Chen & L. Cai, Cladosporium herbarum (Pers.) Link, Lophodermium seditiosum Minter, Staley & Millar, Phialocephala fortinii C. J. K. Wang & H. E. Wilcox and Cadophora finlandica (C. J. K. Wang & H. E. Wilcox) T. C. Harr. & McNew. The richness of the fungal taxa was higher in the needles than in the roots of all the tree species studied. The obtained results could be used for implementing more effective phytosanitary measures in the studied nurseries.

Allozyme Loci

The article presents the results of analysis of the variability of 23 allozyme loci in 10 populations of Siberian Stone pine. Populations from South Siberia mountain regions had higher percentage of polymorphic loci in averageand mean number of alleles per loci (P99% = 44,57 %, NA = 1,543 ± 0,014) compared to Ural populations (P99%=29,57%,NA = 1,348 ± 0,015). The average values of the observed and expected heterozygosity in the populations of the Altai-Sayan (HO = 0,087 ±0,007 and HE = 0,090 ± 0,004) and the Ural mountain region (HO = 0,083 ± 0,008 и HE = 0,082 ± 0,005)were close. About 8.4% of the total genetic diversity is due to differences between the studied populations. The results ofmultidimensional data analysis confirm the existence of the Altai-Sayan and Ural refugia in the post-glacial period andthe dispersal of Siberian stone pine to the North from the Ural glacier refugium.

Forest Drainage

The paper considers the results of forest drain¬age in the Komi Republic and forest research on drained lands. Forest drainage in the republic has been carried out since 1969. The total area of drained forest lands is about 100 thousand hectares. Since 1982, comprehensive research has been carried out on the drained forest lands. The territory of the re-public was divided into the forest drainage area. In the southwestern forest drainage area with a density of 0.7, the aver-age increase in additional volume, depend¬ing on the type of forest, ranges from 0.2 to 3.0 m3/ha per year. Drainage improves the condi¬tions for natural regeneration. In 75% of cases, the regeneration is satisfactory. Drainage posi¬tively affected the growth and regeneration of Pinus sibirica Du Tour, listed in the Red Book of the Komi Republic. Visual assessment of other rare and protected plant species found in forest drainage areas indicates a good or satis¬factory condition of these species and their ad¬aptation to these localization conditions. The total area of protected swamps in the republic (standard swamps and cranberry swamps with cranberries used by the local population for berry picking) is 0.5 million hectares. This area is 5 times larger than the total area of drained forest land. Swamps and forest-swamp com¬plexes recommended for the protection or gath¬ering of cranberries are excluded from forest drainage facilities at the project stage. Addi¬tional new information can be obtained using geographic information systems and remote methods, with the use of growing indices. The half-century experience of forest drainage in the Komi Republic, the results of forest drainage studies indicate that there is no real alternative to hydro-reclamation on forest peatlands. Forest drainage in the republic is the only method tested in industrial conditions to increase the productivity of peatland forests.
