An Analysis of Ephemeral Species in the Fergana Valley Region of the Republic of Uzbekistan According to Grid Mapping

Abstract

Using herbarium specimens kept at the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan and the results of our field studies conducted during 2020-2023, we identified 214 types of species of ephemeral plants that belong to 20 families, 105 species, which grow in the Fergana Valley of the Republic of Uzbekistan, and studied 8317 herbarium specimens. Taking into consideration the fact that to date, no individual research work has been conducted on the ephemeral plants of the Fergana Valley, no grid maps have been created, we demonstrated the grid map of the Fergana Valley, species diversity of indices, accumulations density of indices, distribution of indices by species richness, distribution of indices by accumulations density, distribution of the leading families on the grid map indices, species richness by leading families, accumulation density on leading families, a grid map by species diversity of Brassicaceae, Asteraceae, Boraginaceae, Fabaceae, Poaceae family, and a grid map on accumulation density of Brassicaceae, Asteraceae, Boraginaceae, Fabaceae, Poaceae family. The results obtained allow the conservation of species and their use for many years.
