in this article, Geographical distribution and ecology of Acer semenovii in the Fergana Valley were analyzed on the basis of herbarium data collected in the National Herbarium of Uzbekistan (TASH) and targeted field research in 2020. With the help of field research, new coordinates of the possible distribution of Acer semenovii were recorded, maps representing the distribution of the species were created. Areas with the most optimal conditions for the spread of the species were evaluated and predicted
