| Abstract | ||
| Scorzonera alborzensis is one of the exclusive and rare species collected and reported from only one place in the country (Mazandaran province: between Baladeh and Nour, Siahsang mountains, 3023 m). The genus Scorzonera L. belongs to the Asteraceae family and has 19 endemic species in Iran. Based on the guidelines of the International Union for Conservation of Nature (IUCN), Area of Occupancy (AOO), Extent of Occurrence (EOO), habitat quality, population size, and natural reproduction of the species were evaluated. According to the field studies, the area of occupancy (AOO) and extent of occurrence (EOO) were estimated at an area of 0.01 km2 (only one locality), and the number of adult individuals is between 15 and 20, with a very low regeneration rate. Therefore, according to our studies, Scorzonera alborzensis is defined as a Critically Endangered (CR) species. Road construction and grazing in this species' habitat are among the life-threatening factors. As a result, the Natural Resources and Watershed Organization needs to protect this species' habitat. Further, ex-situ conservation must be achieved by preserving seeds in the Natural Resources Seed Bank, growing seeds, and cultivating seedlings in Iran's National Botanical Garden | ||
