Abstract
The article presents the results of a study (June-September, 2025) on the cenoflora of the relict species Anabasis cretacea Pall. in the Aktobe region. The study confirmed the occurrence of Anabasis cretacea Pall. is associated with Cretaceous uplands and escarpments. Based on the analysis of herbarium materials and field investigations, the distribution sites of Anabasis cretacea Pall. populations were determined in the Khobdinsky and Uil districts, with a description of the identified 9 cenopopulations. The composition of the plant community, as well as the ecological and cenotic characteristics of the populations of Anabasis cretacea Pall. were determined, reflecting the ecological conditions of the calcareous habitats where the studied populations occur. The leading families were Asteraceae (16 species), Brassicaceae (9 species), Chenopodiaceae (8 species), Scrophulariaceae (5 species), Poaceae (4 species). The dominant genera included Astragalus L. (5 species), Anabasis L. (3 species), and Artemisia L. (3 species). Ecobiological analysis confirmed the desert-steppe character of the cenoflora with a minor contribution from meadow species. A complete checklist of cenoflora Anabasis cretacea Pall. was presented, where 84 species belonging to 68 genera and 27 families were identified.
