Abstract
Conservation of existing biodiversity is an integral and essential part into achieving balanced development of human community. One of the main stages on this path is study and inventory of biodiversity of natural and agricultural landscapes of Ukraine. The study was focused on grouping of forest’s and shrub’s vegetation of the Northern black sea area. The collection of material was carried out by geobotanical traditional methods, vegetation;s classification was carried out by using Braun-Blanquet method. As a result of processing of vast array of geobotanical descriptions (876) it was found that in forests and shrubs vegetation of the Northern black sea area there are 9 classes, 10 orders, 16 alliances, 41 associations, 8 non-ranked and 16 derivative groups spreaded. Due to geobotanical data from the studied area it was described new class of natural forest communities Dactylido glomerati-Populetea tremulae. High diversityfigures of forest and shrub vegetation are associated with arena character of Low-Dniper region and with a long history of its formation, as well as isolation of the area from similar sand masses and the peculiar conditions of moisture in the hollows-saucers, which were a prerequisite for the genesis of sandy groves, which became a refugium for unique Dnieper birch and indigenous groups of Dactуlido glomeratae-Populetea tremulae class. Forest and shrub vegetation of the Northern black sea area is divided into four types: natural grouping of steppe vegetation with bushes of participation (class Festuco-Brometea), natural communities of shrubs (Rhamno-Prunetea, Nerio-Tamaricetea, Franguletea), natural communities of forests (Dactуlido glomeratae-Populetea tremulae, Salicetea purpureae, Alnetea glutinosae), anthropogenic tree-shrub communities (Rhamno-Prunetea, Pulsatillo-Pinetea sylvestris, Robinietea).
