The Nodooshan region is a part of Sadoogh Township with 109400 hectars. It located in 80 Km West of Yazd city. Its geographical position is 52, 24 to 53, 47 N and 31, 46 to 32, 15 E. The lowest and highest of its heigh are 1529 to 3260 meters and average annual precipitation reaches between 109 to 220 mm. Flora of this region includes 282 plant species that belong to 204 genera and 48 families. Plant samples were collected between 1995 to 2005 years. The important families are Asteraceae with 44 species (15.6%), Papilionaceae with 27 species (9.57%), Brassicaceae with 25 species (8.86%) and Lamiaceae with 24 species (8.51%) respectively. Studying of plants life form by Raunkiaar method showed that Hemicryptophytes with 37.94 percent (107 species) are the most frequent life forms. Therophytes with 28.72 and Champhytes with 16.31 percent of species are less important. Investigation on geographical distribution of plants species showed 74.47 percent (210 species) of the species belong to Irano-Touranian region. Other species can be observed in other zone too. From the 282 species of flora this region 55 species (19.5%) are medicinal plants, 32 species (11.35%) endemic of Iran and 3 species endemic of Yazd.
