The paper presents the results of a comprehensive analysis of the species composition of Cheboksary. The analysis of the dendroflora of the urban environment was carried out according to 3 indicators: the territory of woody plants, the occurrence of woody plant species in landscaping, the structure of the landscaping system. The arboreal vegetation of Cheboksary is represented by 73 species belonging to 43 genera and 20 families. The predominant part of the dendroflora is represented by the covered-seeded plants (86,3%), the gymnosperms - 13,7%. In the dendroflora of green areas of the city, the most widely represented families are Rosaceae, Pinaceae, Salicaceae (48%). The analysis of the species composition of woody plants showed that in the functional and economic zones of Cheboksary plantings of general use are represented by 65 species, plantings of limited use - 52 species, plantings along the streets and main roads - 50 species. The analysis of the species composition of woody plants depending on the share of their participation in landscaping revealed that the greatest number of woody plants is used with low (51 species) and medium (50 species) share. The analysis of the degree of participation of woody plants in landscaping in the four identified functional and economic zones of Cheboksary found that the greatest number of taxa prevail with an average participation in the central zone (37 species), the coastal and suburban zones (36 species). The largest number of species of woody plants grow in the green areas of the central functional and economic zone, where the landscaping involved 66 species, the smallest number grow in the green areas of the industrial area (36 species).

Trap Nest

Green areas of the city (remnants of the natural landscape, parks, squares, etc.) are a refuge for most diverse organisms, include insects too. Such places provide them with fodder and nesting resources under certain conditions. However, as a result of the sanitary measures of a care, the simplification of the vegetation, etc., these places become unattractive to biota, which leads to the reduction of the most common urbotolerant species of insects. In order to preserve and maintain populations of some insect species, artificial nesting structures are installed in the most attractive and safe areas. We studied the trap nest (a set of reed tubes) for insects, which was located on the territory of the botanical garden NUBIP of Ukraine. As a result of the study of 50 separate nests, the species composition of individual groups of the wild bees and wasps inhabiting such nests was described. Measurements of individual nests (diameter and length of the reed tube) were made and it was found that the population of the insects, in particular Osmia bicornis (Linnaeus, 1758) (Apoidea, Megachilidae) and the wasps of the genus Trypoxylon Latreille, 1896 (Crabronidae) is almost 95 % with dominance of O. bicornis (78 %). It was determined that Osmia are not preferred to the nest with tubes of larger diameter or length, but the diameter and length of the reed tubes are positively correlated with the number of the bees larvae in the nest (the correlation coefficients are 0.44 and 0.48, p = 0.05, respectively). The wasps (Trypoxylon sp.) was preferred to the tubes with a diameter of mainly 0.5-0.7 cm (r = 0.56, p = 0.05). In addition, the composition of kleptoparasites, which lead to the death of the bee larvae, was studied. Thus, 20 % of Osmia nests were infected with flies Cacoxenus indagator Loew, 1858 (Diptera, Drosophilidae), and 10 % of the nests contained pollen mite Chaetodactylus osmiae (Dufour, 1839) (Arachnida, Sarcoptiformes).

Species composition, quantity participation and spreading of ornamental bushes in current system of Novosibirsk green areas are determined. Upper zone (“Verkhnyaya zona”) of Academgorodok is not taken into research as far as it is a cultural heritage site and a significant site of landscape architecture of the 20th century. Special attention is given to participation of lilac species and cultivars (Syringa vulgaris L., Syringa amurensis Rupr., Syringa josikaea J. Jacq. ex Rchb.). It is pointed out that 62 species of bushes are used in the city, including 3 species of lilac, however their quantity participation is not enough and does not satisfy regulatory limits. Twenty six cultivars from the collection Syringa vulgaris L. of the Central Siberian Botanical Garden SB RAS are recommended additionally. Three cultivars, ‘Nadezhda’, ‘Pamyat’ o S. M. Kirove’ and ‘Olimpiada Kolesnikova’, successfully tested in urban environment are highly recommended. Besides, it is recommended to use wider Syringa amurensis Rupr., and to introduce late-flowering Preston hybrids (Syringa x prestoniae Mc. Kelvey (S. reflexa x S. villosa)), curretly absent in green urban areas, in urban greening in Siberia.

Aim: This study was conducted to assessing woody plant composition, population structure and regeneration status in lowland exclosure (EX) of Northern Ethiopia. Study Design: Investigation of parameters was undertaken from 71 plots with size of 20 m x 10 m laid systematically along transect lines for vegetation data. These 200 m2 plots were used for assessment of trees with DBH >5 cm. Small quadrats of 4 m*4 m (16 m2) nested within the bigger plots was laid at the four corners and center of each plots. These were used for measuring seedling and sapling individuals. To analyze species diversity, population structure and regeneration status of woody plants were by computing abundance, density, basal area, Importance value index (IVI) and using Shannon-Weiner diversity and evenness indices. Results: According to vegetation survey result, a total of 23, 17 and 26 woody species were recorded, at Kara, Erba and Shektekli exclosures (EXs), respectively. While 8, 7 and 5 species of woody plant were in open grazing land (OGL). The total mean densities of all woody plants were found to be 1530, 1480 and 2999 individual’s ha-1 at Kara, Erba and Shektekli in EXs. Conclusion: The study suggested that the regional government have to considering EXs as useful for restoration or rehabitation strategy in the region, the vegetation in all the EXs in the study sites have a higher species composition, diversity, density, increment of basal area and regeneration woody plants than OGL, as a result of management differences in EXs. However, there are also variation on species composition, diversity, density increment of basal area and regeneration woody plants among exclosures having similar age and altitude for instance the species recorded in Erba site is lower than with other of EXs, This could be due to among local site characteristic variation and high grazing happen before Ex establishment exists. Therefore, we need to apply soil and water conservation, enrichment planting with indigenous tree species and strengthen local management institution in effectively protect the exclosure.

Currently, there are serious changes in the environment in Almaty due to the accentuated urbanization processes. The avifauna of the city is experiencing serious stress pressure in this regard, which forces the animals to adapt to new conditions or leave this territory. The last fundamental research on the species composition of the city's fauna was conducted about 3 decades ago. The analysis of information on the birds of Almaty, collected by specialists of the Institute of Zoology over the past 50 years, showed significant changes in the avifauna. 5 categories of bird species were identified: 1) species that have disappeared from the urban fauna, 2) species whose numbers have declined significantly, 3) species that have a tendency to decline in numbers, 4) species whose numbers are stable or have increased, 5) species that are settling.

The research object is the territory of the secondary school #19 of the city of Yoshkar-Ola. The topicality of the research is determined by the necessity to reconstruct the existing landscape areas on this territory. For the project “The reconstruction of landscaped areas and improvements on the territory of the secondary school #19”, the authors have reviewed the landscaped areas. The analysis uses complete enumeration based on mensurational description. During the analysis, the authors defined species, taxonomic characteristics, sanitary and hygienic and esthetic values of each taxon. 290 woody plants were examined. Based on the acquired data, the authors analyzed the current landscaped areas on the territory and formulated the following conclusions: the density of plantations is much lower than the recommended values; the authors noticed only the traces of a green fence. However, the average values of the sanitary condition are 2 and 1, which means that the landscaped areas are in a good condition, and the species composition is in line with recommendations. Due to the fact that the school territory radius is 2 km, the condition of landscaped areas requires special attention. The scientific novelty of the research is determined by the fact that the landscaped areas on territory in question need to be reconstructed.

Woody Plant Species

Woody plants species composition, richness, dominance and diversity in west bank forest of International Institute of Tropical Agriculture (IITA) was undertaken to understand the status of the forest. The analysis of tree species composition, richness and diversity in the forest was carried out with the aim of developing efficient management plan that will ensure biodiversity conservation. Vegetation survey using transects and plot sampling techniques were used to collect data for the study. Three transects of 500 m long each {A (270°W), B (90°E) and C (180°S)} were constructed with the aid of prismatic compass in the forest. 10 sampling plots of 10 m by 10 m each were demarcated along each transect making a total number of 30 sampling plots. In each plot, all woody plant species (trees and shrubs) with girth at breast height (gbh) greater than or equal to 10 cm (gbh ≥ 10 cm) were identified, enumerated and measured. The results showed that 581 woody plants belonging to 65 species and 28 families were encountered in the forest. The most abundant family in the forest was Fabaceae sub families of Caesalpinioidea, Mimosoideae and Palpilinoideae. The forest had Simpson diversity index (D), Shannon-Wiener (H) and Evenness index of 0.012, 0.354 and 0.195 respectively. The total density and basal area of woody plants species in the forest was 1,936.67 individuals’ ha-1 and 98.23 m2 ha−1. Newbouldia laevis had the highest density of 190 ha-1 and relative frequency of 9.811% while Milicia excelsa had the highest basal area of 40.34 m2 ha−1, relative dominance of 41.07% and Importance value index of 14.04%. The study concludes that the forest has a reasonably good tree and shrub species composition and richness, dominated by trees and a repository of many indigenous tropical woody plant species. The study recommends in-depth forest inventory, preparation of management plan and promotion of good governance in management of the forest. Also, further studies on regeneration, structure, soil seed bank, seed physiology and herbaceous plant should be carried out in the forest.

Currently, there are serious changes in the environment in Almaty due to the accentuated urbanization processes. The fauna of wild-living vertebrates of the city is experiencing serious stress pressure in this regard, which forces the animals to adapt to new conditions or leave this territory. The last fundamental research on the species composition of the city's fauna was conducted about 3 decades ago, and therefore there is a necessity for repeated research. The aim of the research is to identify patterns of the vertebrates species composition formation within some Park zones of the southern part of Almaty in the context of the last 30 years. The main methods used in the study are route records of vertebrate fauna and bioindication. An analysis of the data from the research centers, as well as the authors' own bio-indicative studies, revealed an unfavourable state of environmental quality. Based on data from the own records (from February to December), it can be concluded that the species diversity of Almaty fauna has decreased or has undergone a considerable territorial redistribution since the end of the twentieth century.

The paper examines the influence of industrial emissions of sulphur (IV) and nitrogen (IV) oxides on the percentage of stem anatomical characteristics of the autochthonous woody plant species undergrowth of Acer platanoides L. and Fraxinus excelsior L. in the southern industrial zone of the city of Dnipro (Ukraine). It is ascertained, that the ratio of the primary cortex share to the central cylinder share does not change in the stems of annual shoots of the both studied woody plant species when they are exposed to the influence of the toxic gases. However, there are significant changes in the ratio of shares of histological elements in the undergrowth stems of F. excelsior. The use of both absolute and relevant values of anatomic parameters of the plant vegetative organs is needed to analyse the woody plants resistance to technogenic pollution of the environment.
