Investigating the habitat of Diplotania damavandica

Degradation of the Earth's biodiversity has resulted in damage that in many cases is irreparable to humans. The purpose of the present study is to determine the boundaries and environment of the proprietary and medicinal species of Kozal Damavandi (Diplotaenia damavandica Mozaffarian, Hedge & Lamond). This plant has received a lot of attention due to the presence of special effective compounds that have therapeutic effects on most skin complications. For this purpose, a habitat map was first prepared with local visits and previous reports. Then, its environment including physiography, accompanying species, lithology, soil and water resources characteristics were studied. The results showed that this plant species grows at the altitude of 2400 to 3600 meters above sea level, with a slope of above 60% and an altitude of above 35ᵒ 40’. Lithological study of the habitat area in dense areas shows the thick green tuffs, Jeirood foundation, shale, and dark sandstone. Also, in terms of soil science, there were significant differences between the examined parameters of K, P, and SO4, while regarding the water resources the significant parameters are Cl and NO3. Investigating the deterioration of vegetation also showed that the highest coverage density in the region was in 2014. The results of the present study will be used to determine the limiting factors of the habitat and to investigate the possibility of the growth of this exclusive species.
