Study of flora, biological shape and geographical distribution of Darbadam pasture area in the territory of nomads

In applied studies to solve ecological problems related to the management and protection of natural ecosystems, it is very important to know and investigate vegetation. Ecological investigation of the vegetation of Zagros forests, which are considered the largest vegetation area in the country, the issue of protection and protection is of particular importance.

Purpose of the research: 

In this study, the flora of Darbadam pasture area in the territory of nomads was investigated.

This area is located at 45°51' to 46°37' east longitude and 33°49' to 34°28' north latitude. The area of ​​this area is about 1000 square kilometers with an altitude of 1335 meters above sea level. According to Amberje's formula, it has a dry and cold climate Geographical area of research: Darbadam is a mountainous region with an average annual rainfall of 414.72 mm. The average maximum temperature is 37°C in August and the average minimum temperature is -20°C in January. The vegetation of this area was studied by floristic method and then their biological forms and geographical distribution were determined.

In general, there are 41 genera, 145 genera and 225 species in the region. Out of 145 genera, 27 genera (18.62%) and 36 species (16%) belong to monocots and 118 genera (37 81.) and 189 species (84%) belong to dicotyledons. The largest plant families in terms of the number of species are: Compositae with 33 species, Papilionaceae with 24 species, Poaceae with 18 species, Lamiaceae with 15 species, Boraginaceae with 13 species, Apiaceae with 12 and Liliaceae with 12 species. The life forms of plants in the region according to the Rankier method include 44.8% of phanerophytes, 22/ 10% is cryptophyte, 41.33% is hemicryptophyte, 2.66% is camphyte and 36.44% is trophyte.

The study of the geographical distribution of the flora of the region showed that the most geographical distribution is related to the Iranian-Turanian region with 124 species (55.11%) and the Iranian-Turanian/Mediterranean region with 39 species (17.33%). The high percentage of Iranian-Turanian elements shows that the protected area belongs to this phytochorion.
