چکیده مقاله:

In terms of climatic and ecological diversity, Iran has a relatively rich and unique flora, and the endemic condition of some plant species has caused the global importance of Iran and its dependent flora. Endemic species are considered as the most important plant species in the country. Iran with more than 126 species of Allium L. is one of the important centers of its diversity. In this research, the conservation status of an endemic species of onion in Iran is determined according to the criteria of the International Union for Conservation of Nature (IUCN). Based on field studies and a survey of 59 accessions from different areas of the distribution of this species in the years 96-92, using three criteria for extent of occurrence (EOO), occupation level (AOO) and number of population and calculations performed by Geocat software, A. ubipetrense R.M. Fritsch despite the presence of relatively numerous habitats, is considered to be rare and vulnerable or endangered plants due to its limited occupation and small populations, and should be studied in terms of conservation. In most of these habitats, individuals of this species are very limited and, in many cases, are seen singly. Given the total number of factors including individual numbers, fertility rates, highly dispersed accessions, limited restoration due to limited seed production and degradation of habitats, which aregenerally due to various reasons, including warming and excessive weathering, this species is endangered.
