“…Localized ecological systems are known to pass dramatically and irreversibly from one state to another when they forced to cross critical thresholds; it highlights the need to improve biological forecasting by identification of early warning signs of critical transitions at global as well as regional scales (Barnosky et al, 2012;Asif et al, 2018). Nowadays, the valley of the Liman Kuyalnik is in a state of ecological disaster (Dubyna et al, 2018b;Ennan et al, 2018). The established relationships in ecological differentiation of plant communities will be applied to further monitoring of the biodiversity state, preservation and possible restoration of vegetation types that are, or were, native for this unique territory.…”

Assessment of key environmental factors that influence vegetation distribution and formation of plant communities is one of the most important challenges in modern phytocenology. Nowadays, several bioindication systems are applied to determine ecological specificity of plant communities and to establish the leading factors for their environmental differentiation. The system most widely used in Europe, that of H. Ellenberg, contains a numerical score on 6 ecological factors. On the example of vegetation of the valley of the Liman Kuyalnik, Y. Didukh developed the synphytoindication method based on evaluation of phytocenoses with respect to 12 ecological factors: 7 edaphic factors and 5 climatic factors; the method determines a more accurate and complete presentation of the analysis. In the valley of the Liman Kuyalnik (Odesa Oblast) the largest area is covered with halophytic and steppe vegetation. Halophytic vegetation (Therosalicornietea, Festuco-Puccinellietea classes, Juncetea maritimi, Bolboschoenetea maritimi) predominated in the shoreline areas of the valley, whereas steppe (Festuco-Brometea) and petrophytic (Sedo-Scleranthetea) vegetation dominated on the slope sites. With the application of DCA-ordination and synphytoindication methods it was established that distribution of plant communities in the hyper-space of the environmental conditions was most strongly correlated with edaphic factors, whereas microclimatic (light intensity) and climatic (thermo-regime) conditions had somewhat less influence on their differentiation. Water regime and level of soil salinity served as key factors for syntaxa of halophytic vegetation; moisture variability and salt regime, as well as soil moisture and carbonate content were key factors for the steppe vegetation, and thermo-regime was the main factor for petrophytic-steppe and petrophytic vegetation. The "eco-spaces" of these groups largely overlap. Halophytic cenoses are characterized by quite wide ecological ranges by most ecological factors. Steppe communities show much less ecological diversity. In the valley of the liman, all the steppe communities were characterized by stenotopicity in relation to most ecological factors; these factors complexly determine the specificity and diversity of biotopes within the valley, which are unique and require protection and the taking of appropriate measures, depending on the changes in activity of one or another limiting factor. Nowadays, the valley of the Liman Kuyalnik is in a state of environmental disaster. The established relationships in ecological differentiation of plant communities will be applied to further monitoring of biodiversity state, preservation and possible restoration of vegetation types that were native for this unique territory.

“…Їхню біотичну основу складає фіторізноманіття схилів, яружнобалкових екосистем та відслонень понтичних вапняків і лесів, а також прилиманних і надлиманних кіс та островів. Формування їхньої рослинності відбувається під впливом динамічних процесів, що характеризуються неперервною мінливістю (Dubyna et al, 2017с;Ennan et al, 2018). Розвиток рослинності схилів, кіс та островів укладається в єдиний, чітко виражений цикл, у якому встановлюються функціональні взаємозв'язки між зміною екологічних умов і перебудовою структури угруповань.…”

“…Тому екосистеми Куяльницького лиману та прилеглих територій мають велику природно-історичну цінність. Завдяки зміні екологічних умов від напівпустельних до перезволожених, а також піонерних та субклімаксових (окремі приплакорні, що не зазнають трансформації ділянки) типів організації рослинності, вони відзначаються найвищим рівнем біорізноманітності у степовій зоні Євразії (Ennan et al, 2018). Поєднання мегагалофільних, пустельно-степових, чагарниково-степових і зонально-степових біотопів та їхніх раритетних компонентів визначає високий природоохоронний статус території куяльницької геосистеми, насамперед, завдяки типовим та ендемічним флористичним і ценотичним комплексам з високим рівнем багатства гено-та ценофонду (Krytska, 1985(Krytska, , 1988.…”

The present state of ruderal vegetation in the valley of the Kuyalnyk Liman is clarified, and its phytocenotic diversity is established. The largest syntaxonomic riches has the class Stellarietea mediae (13 associations, 7 alliances and 3 orders). Artemisietea vulgaris has 10 associations, 4 alliances and 2 orders and Polygono-Poetea annuae-1 association, 1 alliance and 1 order only. The new association Amarantho blitoidis-Tribuletum terrestris are described. Agropyretum repentis, Hordeetum murini, Melilotetum albo-officinalis, Chamaeplietum officinalis, Lactucetum tataricae, Anisantho-Artemisietum austriacae, Polygonetum arenastri are most widespread associations on the investigated area. These associations are quite characteristic for the whole of Western and Eastern Europe, including Ukraine, but thermophile communities Bromo squarrosi-Sonchetum oleracei, Lactucetum tataricae, Anisantho-Artemisietum austriacae, Calamagrostietum epigei, Amarantho blitoidis-Tribuletum terrestris and Cynodontetum dactyli are present here. It is observed the increase in area and the number of ruderal communities of thermophilic annuals, due to the catastrophic reduction in recent years a water surface. Ruderal vegetation of the region is formed by synanthropic phytocoenoses and genetically previous formations of natural vegetation. There is a significant proportion of aboriginal species (up to 55 %) in floristic composition of ruderal communities. It indicates the possibility of renaturalization of natural vegetation, while reducing anthropic pressure. The wide distribution and diversity of ruderal vegetation, and its high degree adventization, testify to the threatening ecological situation in the region and a significant level of anthropic transformation of natural communities. Optimization and restoration of semi-natural and anthropic ecosystems of the Liman are necessary. The creation of the Kuyalnytskyi National Natural Park is the only solution of this problem.
