Floristic studies of a region have many advantages, since the floristic list is a useful identity document which provides the genetic potentials of the area. The area of Hanna no-hunting zone is 20452 ha and is located at the southern part of Isfahan province. In this study the floristic list of the region is presented and their life forms and endangered species are stated. Field data collections were conducted during the years 2007 through 2008. First the studied area boundaries were exposed on a topographic map with a scale of 1:25000. Then, the plant species of the region were collected and identified according to the floras. According to the presented list, there were 307 species belonging to 209 genuses which are classified in 51 families. The Asteraceae has the highest species diversity in the region with 33 genus and 52 species. According to Raunkiaer’s life form criteria, the identified species are categorized as: hemicryptophytes 50.5%, therophytes 23.1%, chamephytes 11.4%, phanerophytes (6.8%) and geophytes (8.1%). The high percent occurrence of the perennial species confirms the plant species adaptations to the climatic and edaphic conditions of the region. In the Hanna region, 76 medicinal and industrial species were listed belonging to 67 genera and 29 families. The Asteraceae and Lamiaceae families had 12 and 13 species of the medicinal plant species accordingly and they had the most species diversities in this category among the other families. There were 9 vulnerable species, 28 lower risk and 4 data deficient species in the studied region.
