A Preliminary Survey of Flora, Life form and Chorotype of Plants of the Booz Daghi Region in North Khorassan Province
The Booz Daghi region with an area of 62,000 hectares is located 47 kilometers from Maneh and Semelghan city. The floristic composition, biological, and chorological spectra of this area were investigated through several random collections in different habitats and vegetation types, as well as from 220 plots established in selected plant communities during the growing season of 2021. In this regard, 252 vascular plant species belonging to 173 genera and 53 families were recorded as native plants in the Booz Daghi region. The richest families were Asteraceae (31), Poaceae (25), Lamiaceae (22), and Fabaceae (21). The genera Astragalus L. (10), Allium L., Convolvulus L., and Stachys L. (each with 5 species) were the richest ones. Hemicryptophytes (31.3%) and therophytes (29.8%) were the dominant life forms of the region. A considerable number of species (63.5%) belonged to the Irano-Turanian region. The results of this study showed that the Booz Daghi region had a relatively rich flora that requires special attention and proper planning to protect its biodiversity.
