A Floristic Study and Comparison of the Core and Buffer Zones of the Tange-Khoshk Forest Reserve of Semirom in Isfahan Province

In the present study, the flora of Tange-Khoshk Forest Reserve of Semirom in Isfahan with two zones, the core zone (under protection) and the buffer zone, was investigated to introduce the floristic composition, life forms, and geographical distribution, and understand the effects of exclosure on the vegetation structure. In this region, a total of 194 species belonging to 45 genera of plants were identified, of which Asteraceae, Fabaceae, and Poaceae were the most abundant in terms of the number of species. In terms of life forms, hemicryptophytes were dominant in both core and buffer zones. The study of the geographical distribution of the species showed that in both core and buffer zones, most species belonged to the Irano-Turanian vegetation area. This research showed that the exclosure of the Tange-Khoshk forest reserve had increased the diversity of vegetation, especially the presence of various tree species in the core zone.
