The results of introduction studies of 15 Caucasian species of the genus Primula L. (Primula abchasica, P. acaulis, P. algida, P. amoena, P. cordifolia, P. darialica, P. farinosa, P. juliae, P. komarovii, P. macrocalyx, P. pallasii, P. ruprechtii., P. saguramica, P. sibthorpii, P. woronowii) conducted in the Polar-Alpine Botanical Garden and Institute are presented. Currently, the institute’s collection contains 8 species (P. acaulis, P. amoena, P. juliae, P. macrocalyx, P. pallasii, P. ruprechtii, P. saguramica, P. woronowii). Ecological and geographical analysis has shown that the species best adapted to the conditions of the Arctic are those that live in the alpine (P. algida, P. amoena, P. cordifolia, P. juliae, P. pallasii, P. ruprechtii, P. sibthorpii – introduction coefficient [IC] =9.4) and subalpine zones of mountains (P. macrocalyx, P. acaulis – IC=8.2). While plants found in the broad-leaved forest zone are less adapted to the new living conditions (P. komarovii, P. saguramica, P. woronowii -IC=6.4). The current research establishes that species of the genus Primula can serve as a source of plant assortments to replenish landscaping in cities in the Murmansk region. For this purpose two new decorative and sustainable species (P. macrocalyx h P. ruprechti) are recommended.

Vegetation cover and environmental factors were studied in the system of karts mires in the broad- leaved forest zone in Tula Region, Central European Russia. Mires are formed in the sinkholes and characterized by rather low anthropogenic disturbances. These mires are characterised by floating peat mats and variety of vegetation communities which are differ by ecological conditions (water levels, acidity and nutrition). Development and growth of floating mats change water and mineral feeding that leads to succession of vegetation communities.

The comparative analysis of floristic composition of the Russian Plain center broad-leaved forests of the alliance Carpinion betuli Issler 1931 em. Meyer 1937 was carried out by means of detrended correspondence analysis (DCA) and direct ordination along ecological factor scales. The three associations representing the proper zonal units of the area, namely Querco-Tilietum cordatae Laivinš 1983 in the hemiboreal forest zone, Aceri campestris—Tilietum cordatae ass. nov. hoc loco in the broad-leaved forest zone, and Aceri campestris—Quercetum roboris Bulokhov et Solomeshch 1991 in the forest-steppe zone are characterized. Although all the forest stands described are small geographically isolated fragments, their floristic composition demonstrates the existence of syntaxonomic continuum and seems to be influenced by landscape features and anthropogenic disturbance just as strong as by zonal climatic factors. As a result of the undertaken analysis, the syntaxonomical revision of the Central-Russian broad-leaved forests of the alliance Carpinion betuli Issler 1931 em. Meyer 1937 is proposed.

The paper presents the results of introduction studies of 20 European species and 2 taxa of the genus Primula L. in N.A. Avrorin Polar-Alpine Botanical Garden-Institute of Kola Scientific Centre of Russian Academy of Sciences. Currently, the collection contains 13 species and 1 taxon ( P . auricula L., P . carpathica Fuss, P . clusiana Tausch, P . daonensis (Leyb.) Leyb., P . elatior (L.) Hill, P . glaucescens Moretti, P . kitaibeliana Schott, P . latifolia Lapeyr, P . minima L., P . poloninensis Fed., P . veris L., P . veris subp. macrocalyx (Bunge) Ldi, P . vulgaris Huds., P . wulfeniana Schott). It has been shown that the species inhabiting the alpine belt of mountains are best adapted to the conditions of the Arctic ( Primula auricula , P . carpathica , P . clusiana , P . halleri , P . minima , P . pedemontana , P . scandinavica , P . vulgaris ssp. rubra , P . tyrolensis , P . wulfeniana - IC (introduction coefficient) = 8,3, as well as P . elatior (IC = 8,1) and P . veris subsp. macrocalyx , P . vulgaris (IС = 7,6). The rest of the studied species are less adapted. It has been established that species of the genus Primula can serve as a source of replenishment of the landscaping assortment for the Murmansk Region. For this purpose 2 new ornamental and resistant species were recommended ( Primula carpathica , P . clusiana ).

East European forests dominated by Norway spruce (Picea abies (L.) H. Karst.) in the broad-leaved–coniferous zone should be considered as secondary communities formed under the influence of centuries-long activities (logging, fires and planting) and extended outside their natural range. The study raises an issue—how stable is the current state of Norway spruce forests in the center of the Russian plain and what is the effect of silviculture on the forest cover of the large urban agglomeration—the Moscow Region? Current study is based on multidisciplinary research and consequently concerns the age dynamics of spruce plantation forests, the species and typological diversity of mature spruce forests and spatial pattern of spruce forests along the south edge of their range. The composition and structure of Norway spruce plantations have been studied for various age classes and compared with mature natural spruce forests and pine plantations on the basis of field data. Remote sensing data and modeling approach were applied to estimate the spatial structure of spruce forests. It is found that mature plantations (over 80 years) become similar to natural forests in terms of structure and composition. The relationship between the distribution of spruce formations and the climatic and geomorphological conditions are confirmed. The proportion of spruce and spruce–aspen/birch communities follows the pattern of zones—the transition from the coniferous and broad-leaved forest zone to the broad-leaved forest zone. Despite the significant anthropogenic impact and the high proportion of plantations in the composition of Norway spruce forests (about 60–80%), their floristic and typological diversities correspond to such properties of zonal broad-leaved–coniferous communities. Over-matured plantations can provide valuable habitats for the re-establishment of native typological diversity. This makes it possible to use silviculture stands as an accelerated alternative to the natural recovery of disturbed habitats.

The tropical seasonal rainy evergreen broad-leaved forest vegetation of the Cucphoung National Park has been classified and the distribution of plant communities has been shown on the map using the relations of vegetation to geology, geomorphology and pedology. The method of vegetation mapping includes: 1) the identifying of vegetation types in the remote-sensed materials (aerial photographs and satellite images); 2) field work to compile the interpretation keys and to characterize all the communities of a study area; 3) compilation of the final vegetation map using the combined information. In the classification presented a number of different level vegetation units have been identified: formation classes (3), formation sub-classes (3), formation groups (3), formations (4), subformations (10) and communities (19). Communities have been taken as mapping units. So in the vegetation map of the National Park 19 vegetation categories has been shown altogether, among them 13 are natural primary communities, and 6 are the secondary, anthropogenic ones. The secondary succession goes through 3 main stages: grassland herbaceous xerophytic vegetation, xerophytic scrub, dense forest.
