Shomurodov H.F., Adilov B.A. THE CURRENT STATE OF THE VEGETATION OF VOZROZHDENIYA ISLAND, UZBEKISTAN // Arid ecosystems. 2019. V. 25. № 2 (79). P. 27-34. | PDF

The preliminary floristic composition of vascular plants of Vozrojdeniya Island (an enclave of the Aral sea) within its limits in the Karakalpak part (Uzbekistan), numbering 123 species from 90 genera and 31 families, is established. In terms of species richness, the spectrum of the leading families is headed by Chenopodiaceae Vent., Asteraceae Dumort., Fabaceae Lindl. and Poaceae Barnhart families. Similarities (for example communities of Anabasis salsa and Artemisia terrae-albae) and distinctive features (for example, Salsola arbusculiformis, not acting as dominants and the lack of vegetation complexes consisting of Anabasis salsa, Artemisia terrae-albae and Salsola arbuscula) vegetation of the island with Ustyurt. On the other hand, large areas of the island are occupied by the communities of Salsola orientalis and Haloxylon aphyllum, resembling separate ecotopes of Kyzylkum. The predominance of the Artemisia terrae-albae formation in some parts of the island is associated with low anthropogenic impact due to the isolation of the island from the mainland for a long time.

Keywords: flora, vegetation, Vozrojdeniye island, Ustyurt plateau, Kyzylkum, endemics.
