Botanical study on plant species of Zagros folded and thrust belt in northwest Fars in Qalat region to reconstruct paleoclimate of the area based on the plants' evolutionary history

This study is related to the investigation of plant species of Zagros folded and thrust belt in Fars province (of Iran) in Qalat region. In this study, only trees have been examined such as Pear, Plum, Hawberry, Cherry, Apricot, Common medlar, Apple, Peaches, Platanus, Green Tomato, Grapes, Populus, Walnut, Pistacia terebinthus, Willow, Fraxinus excelsior, Barberry, Figs, Pomegranate. Based on the studies on the plant species, twelve families which are Rosaceae, Platanaceae, Solanaceae, Vitaceae, Salicaceae, Juglandaceae, Anacardiaceae, Ebenaceae, Oleaceae, Berberidaceae, Moraceae, Lythraceae, and nineteen genera that are Pyrus, Prunus, Crataegus, Medler, Rubus, Malus, Platanus, Solanum, Vitis, Populus, Juglans, Pistacia, Salix, Diospyros, Olea, Fraxinus, Berberis, Ficus, Punica, were found and determined. To investigate the paleoclimate of the region, the evolutionary history of plants was studied. In the past, the region has more experienced warm and humid, temperate and subtropical climate because most of the plants' families belong to the Cretaceous, Paleocene, Eocene, and Oligocene. Also, Rosaceae with the age of Late Cretaceous is the largest family of the region lived in a warm and humid environment. In contrast, the modern weather of the area has mild and humid in summers and cold and humid in winters.
