Chorology, Biological Form and Composition of Species of Plant Elements in the southern slopes of the mountain ranges of Garmeh Malayer

The flora of each region is the result of the biological responses of plants to current conditions and the evolution and adaptation of plants from the past to the present. Plants are one of the main pillars of ecosystems and their scientific identification in relation to their growing environment is of great practical importance. The aim of this study was to introduce the biological form and composition of plant elements in the southern slopes of Garmeh Malayer mountain rangelands in Hamadan province in 1396 and 1397. During field visits and surveys, plant species were photographed, collected and all plant species in the study area were identified and a total of 167 plant species were identified in the area. These species belong to 24 genera and 114 plant genera. Among these plants, the genera Compositae with 33, Leguminosae with 22 and Graminae with 18 species have the highest diversity. The chorology of the species also showed that the most abundant growing element in the region is related to Mediterranean-Iran Turanian (37%), Iranian Turanian-native (28%) and Mediterranean, as well as Siberian Europe (22%), respectively. . Also, the classification of plants based on Rankier biodiversity showed that there were 69 species of therophytes, 47 species of comfits, 9 species of cryptophytes and 42 species of hemicryptophytes. Most of the plants in the area are trophies, which indicates the destruction of these lands. Most of the plants identified in the area in terms of function were forage, wildlife and biodiversity, respectively; Perennial species also had the highest distribution in the region. The floristic study of plants in each area is important in terms of biodiversity recognition and natural resource management; Because one of the most important methods for recognizing the capacity, management, conservation of biodiversity reserves and preservation of genetics of vulnerable plants is the study of flora, which can provide valuable information to better understand, understand and manage the natural features of this area provided.
