Abstract :

Background and Objective: Calligonum eriopodum is a sand-loving shrub that is native to Iran exclusively in the sand dunes of Hemmat-Abad, Zirkuh-e-Qaen (South Khorasan). The conservation status of this rare and suitable plant for stabilizing quicksand and reducing wind speed was determined according to International union Conservation of Nature (IUCN) criteria. Material and Methodology: The conservation status of this rare species was determined according to IUCN criteria, using GeoCat online software, with field surveys in its habitats, and the area of occupancy (AOO) criterion and extent of occurrence (EOO) calculation. Finding: The area occupied by the Scanbil species was estimated by field surveys and then by GeoCat software in its habitats: AOO was 20 Km2 and its presence area was 53.8 km2. Discussion and Conclusion: According to the results of this study, this species is in the critically endangered class (CR). Surveys have shown that severe falls in water table drown down and unprecedented droughts of the last decade have been considered major contributors to this rare shrub, that needs to be protected as a natural genetic reserve.
