Abstract: (3370 Views)

Iran enjoys high vegetation diversity due to different climates and ecological conditions. Golestan is one of the well-known provinces with diverse flora in the country. Of the plant species of the country, Juniper genus habitats with the presence of 6 native species are one of the few needle-leaves that their under-story flora has not been collected and reported scientifically so far. Chahar Bagh Juniper Reserve with an area of 600 hectares, located in the southern part of Gorgan, with altitude range of 2150 to 3150 meters above sea level, was selected as a study area. In order to identify plant species and to introduce the floristic composition, biological form and geographical distribution of plants in the area, Plant specimens were collected and identified during the growth seasons of 2017 and 2018. The results show that in total, the under story flora of Char-Bagh Juniper Reserve has 109 taxa including 80 genera and 33 families. The largest families, belonged to the Poaceae (12 species), Lamiaceae (11 species), Brassicaceae (9 species), Asteraceae (8 species), Apiaceae (7 species) and Alliaceae (7 species), respectively. According to Raunkiaer's biological form, 44% of plants belong to the hemicryptophytes, 22% in therophytes and 12% in camaephytes. An examination of the geographical range of vegetation in the area reveals that 61.3% of identified plants belong to Iran-Turanian vegetative zone and 7.2% of the species have European-Siberian origin and at the same time, 2.7% of the species stand in between. In addition, 9.9% of the species are common between the Iran-Turanian and Mediterranean vegetative regions and the remaining 18.9% are related to other vegetative areas or are shared between several vegetation areas. The conservation status of the plant species in the area showed that none of them were endangered. One species is in the group of less threatened (relatively vulnerable) plants and one species is in a group with insufficient information on their condition.
