abstract

Anthropogenic hydrotechnical changes in the the left-bank part of the north-western Black Sea region have led to significant changes in the Black Sea steppe: the channel system has become a conductor in the steppe zone of mesophytic plant species, the formation of wood-shrub, halophytic-meadow and swamp groups along irrigation canals, the formation for southern Ukraine non-distinctive of cenosis in conditions of unstable salt and hydrological regimes of territory, distribution of areas of transformed natural groups with the participation of ruderal and adventitious species. The system of irrigation and drainage channels has become a conductor of unspecified species of plants and animals for the Black Sea steppe. Changing the vegetation has led to the disappearance of a number of zonal species of animals, including many protected species, and invasions of species of intranasal, widespread, alien species. From the Dnepr to the North - Crimean, Krasnoznamensky canals, then the irrigation system got to the coastal steppe zone muskrat, which was acclimatized in the Dnieper in 1944. A muskrat appeared in 1971 at the Potiivska site of the Black Sea Biosphere Reserve (BSBR), located in the eastern part of the Tendrivsky Bay on the Black Sea coast. By 1980, the number of muskrat was increasing, from 1983 to 1995 remained at a high stable level. Since 1995, the number of muskrat has plummeted. In 20002010 due to the destruction of irrigation and, respectively, the drainage system hut was no registered in the lakes of Potiivska part of the Black Sea Biosphere Reserve. In the Black Sea steppe we observed a restorative succession. Since 2010, the restoration of rice growing, since 2014, the full irrigation has been restored. Further dynamics of the number of Ondatra zibethicus in the Black Sea steppe was determined exclusively by anthropogenic factor.
