The article presents the results of studying the coenopopulations of Moneses uniflora (L.) A. Gray (familyEricaceae Juss.) found during the monitoring of vegetation formation on the dumps of the mining and processing industryof the Sverdlovsk region (Middle Urals, southern taiga subzone). Studies have shown that the M. uniflora (family EricaceaeJuss.) coenopopulations in plant communities formed on industrial dumps and in natural phytocenosis are normal, fullfledged, young. The morphological parameters of generative individuals are significantly influenced by coenotic andedaphic factors. Arbutoid mycorrhiza was found in the thin roots of M. uniflora in all the studied habitats.

Element Accumulation

The paper considers the macro- and micro- element composition of two ash dumps in the Middle Urals, where meadow and forest communities have been spontaneously forming for 50 years, as well as the effect of the plants on the changing composition of the ash. Higher contents of Cu, Co, Sn, Ga, and Yb were found in the deep ash layers of both dumps, while in the upper 20-cm layer, the trace element composition depended on the influence of different plant communities. Higher contents of Sr, Cr, Ni, Sn, and Co were revealed under meadows, and Ba, Zr, and La were found under the forest. The levels of element accumulation in the aboveground and underground parts of dominant plants were revealed. Increased content of Be, Ce, Ga, La, Sc, Y, and Yb was detected in areas where meadow plants were dominant and Zn and Ba in forest areas. The toxic elements Cd and Pb were highly accumulated in both communities, whereas Co was found only in meadows. The studied materials can serve as a base to assess the feasibility of processing and/or utilizing fly ash from ash dumps in the Middle Urals and similar ash dumps in other regions situated in the southern taiga.

As a result of a generalization of 45-year monitoring observations at on the ash dump of the Verkhniy Tagil Power Station, the absolute time scale was made, stabilization rates during succession of different plant communities characteristics were assessed in two areas: recultivated and non-recultivated. Recultivation consisted of clay strips applying (5–8 m wide, 10–15 cm thick) on ash surface. All characteristics of plant communities (total projective cover by plants, total number of species in plant community) are formed 15–20 years faster in recultivated area. So, a simple technical recultivation, (clay strips applying), significantly accelerates the formation of plant communities main characteristics on ash surface in subzone of the southern taiga in Middle Urals.

Rather large forests, typical of the southern taiga subzone are preserved within the boundaries of St. Petersburg. They include a wide variety of plant communities with some rare species. This article is devoted to the area located in the southern part of the city and designed as a nature reserve. A large-scale map of actual vegetation of the projected reserve was composed; it shows the diversity of plant communities and their distribution. The map legend consists of 75 main units; and the usage of supplementary symbols helps to map 122 units. Areal analysis of all types of plant communities is carried out on the basis of the vegetation map. Typical and the most valuable vegetation objects were identified.

Under conditions of introduction into the subzone of the southern taiga of the Middle Urals, species that are little known as medicinal plants in European countries and in Russia have been studied. These species have a wide spectrum of pharmacological action and are promising for use. Success of introduction was the most for Agastache foeniculum (Pursh) Kuntze, A. scrophulariifolia (Willd.) Kuntze, A. urticifolia (Benth.) Kuntze, Echinacea pallida (Nutt.) Nutt., Campanula rapunculoides L., C. latifolia L. These species are characterized by high winter hardiness, stable fruiting, give self-seeding, accumulate a sufficiently large biomass, are not damaged by diseases and pests.

Research subject. The article presents the results of dating two dolerite dikes differing in geochemical features from a section along the Iset river in the area of Smolinskoe settlement (the Eastern zone of the Middle Urals). Materials and methods. The dating was performed by an U-Pb ID-TIMS technique for single zircon grains using an artificial 205Pb/235U tracer in the laboratory of geochronology and isotope geochemistry of the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences. The lead isotopic composition and uranium and lead concentrations were measured using a Finnigan-MAT (RPQ) seven-channel mass spectrometer in dynamic mode using a secondary electron multiplier and RPQ quadrupole in ion counting mode. Results. The dikes were dated 330 ± 3 Ma and 240 ± 2 Ma. Conclusions. The research results indicate different ages of dolerite dikes developed within the Eastern zone of the Middle Urals. The oldest of the two established age levels corresponds to the Early Carboniferous era. This fact, along with the proximity of the dolerites to the petrochemical features of the basaltoids of the Early Carboniferous Beklenischevsky volcanic complex, allows these bodies to be considered as hypabyssal comagmates of these volcanics. The youngest obtained age level – Triassic – indicates that the introduction of some dolerite dikes was associated with the final phases of the trapp formation developed rarely within the eastern outskirts of the Urals and widely further east in the foundation (pre-Jurassic basement) of the West-Siberian Plate.
