Abstract

The geographic distribution of Astragalus (FABACEAE) in IRAN was analyzed using a database of 7606 georeferenced observations. Astragalus occurs in all provinces of IRAN, but 88% of the observations are in five provinces including Tehran, West-Azerbaijan, Esfahan, Kordestan, and Khorasan-e Razavi. Most species are rare and narrowly endemic: The largest distance between two observations of the same species for 451 species is <200 km. The highest number of species (154 species) was known from Esfahan Province, followed by East-Azerbaijan with 149 species. A grid of 30 × 30 km cells were used to map the SPECIES RICHNESS. There are 794 cells with observation on grid map. To include all species of Astragalus, 269 selected cells are enough. High SPECIES RICHNESS occurs only in northern half of country especially in north-west of the IRAN. Regions with high richness include Central-Alborz Mountain in north, North-Zagros Mountain in west, Mountain of north-west corner of IRAN, and Khorasan-Kopet Dagh Mountain in North-East. The highest number of species in a grid cell (43 species) occurs in Avaj between Qazvin and Hamedan. Astragalus species occur between 30° N and 38° N. Astragalus species widely distributed in mountainous regions especially between 1000 and 3000 m altitude.
