Ecological and biological aspects of assessing woody plants in the landscaping of Novosibirsk

Abstract

The ecological and biological characteristics of woody plants growing in the most popular squares of the Novosibirsk city (Teatralny, Pervomaisky, and Slavy square) have been investigated. 73 species of woody plants have been recorded. 13 of them are common to three landscape objects. Ornamental garden forms of woody plants are found separately (13 intraspecific forms, hybrids and varieties of woody plants). Some species of molded plants that are not suitable for landscaping public urban space due to their low winter hardiness were recorded. The greatest species diversity is distinguished by the green spaces of the Slavy square. The correlation between the place of growth and the vital state of plants has not been found. Plants on the objects are in satisfactory vital condition. Species in an unsatisfactory condition are found singly. Shrubs (49% of the total) and trees of the first and second sizes (32%) predominate in terms of life forms. The plantations contain species of natural flora of the Novosibirsk region and introduced plants from other geographic regions (27 and 73%, respectively). Among the introduced plants, species with a wide Eurasian type of area prevail. Analysis of the history of the creation and reconstruction of landscape objects showed that the assortment of plants on the territory of Pervomaisky Square has changed to a greater extent, the species composition of plants in the Teatralny Square has changed insignificantly. To form a better spatial structure of landscape objects, we recommend to increase the species and form diversity of plantings by introduction of plants of various life forms and species that have passed introductory tests in local climatic conditions. This will provide the creation of landscapes and landscape compositions of various expressiveness and to form a comfortable environment for the rest of the citizens.
