Abstract


Steppe areas of the National Natural Park "Kremenets Mountains" occupy the minimum area in open hills and rocky niches, so the priority tasks are the protection of unique steppe ecosystems.

Reproduction of steppe areas is one of the tasks aimed at preserving the diversity of steppe and petrophytic flora, the structure of cenoses in the steppe regions, as well as the habitats of rare steppe plants.

The work is based on field research materials conducted during 2012-2018 on the territory of the National Natural Park "Kremenets Mountains". In the course of research, literary data and geo-botanical studies of the Strahov, Vovcha, Sokolina, Maiden cliffs and Zamkov mountains have been processed, flora and phytocenotic features of steppe and meadow-steppe phyto groups, the state and structure of rare species populations have been described.

Characterized by the laws of distribution of steppe and meadow-steppe species of plants on the territory of the National Nature Park "Kremenets Mountains". The influence of natural conditions is described, factors which contribute to the decrease in the number of populations of these species are determined. The measures on preservation and reproduction of steppe ecosystems, preservation of the diversity of steppe and petrophytic flora, and the structure of the cenosis of the steppe regions are presented. The age structure of Adonis vernalis L., which grows on the Malyatyn and Vovchyna rivers, is studied.

In order to preserve the populations of the listed rare steppe plant species, active measures have been taken within the framework of the National Natural Park "Kremenets Mountains", which consists in reducing the anthropogenic impact and restoring the settlement of rare species. According to the Territory Management Project, the state of afforestation of steppe areas is monitored, shrubs, undergrowth of trees and invasive herbaceous plants (in particular, Solidago canadensis L.) are cleared with which the steppe areas spontaneously grow; some measures are taken to increase the number of rare plants (repatriation).

This will promote the expansion of steppe areas, the increase of the proportion of steppe and meadow species in the grassland and increase the area under the populations of individual rare species.
