The Ziadin-Zirabulak botanical-geographical region belongs to the Kuhistan district and the Mountainous Central Asia province, located within the Samarkand and Navoi regions. This area is characterized by diverse climatic conditions, with temperatures ranging from +12°C to +16°C and annual precipitation from 172 mm to 395 mm. The floristic checklist of the region has not been fully developed, and discrepancies exist between recorded and observed species. This study, conducted through fieldwork from March to end of May 2025, resulted in more than 2500 observations uploaded to the iNaturalist platform. The findings made it possible to identify 13 species previously unrecorded for the Ziadin-Zirabulak region. These results offer new insights into the flora of the area and contribute to a deeper understanding of its biodiversity and ecological significance.
