- AbstractThe altitude, exposure factors and some landforms and parent materials create different environments and/or habitat for the growth of plants belonging to the several phytogeographic regions in the mountainous areas. The mountain ranges in Turkey bring about the formation of different habitat both in the growing of relic and endemic plant species and the plant communities belonging to adjoining phytogeographic areas. For example, the high part of the Northern Anatolian Mountains, the Mont Ararat, the Erciyes mountains and Nemrut volcanic caldera are the main shelter area of the plants of the Last Glacial period in the Anatolia. Indeed, the high parts, especially northern slopes of the above mentioned mountain areas produce a favourable condition for the growth of Euro-Siberian plants. In other words the plants which spread during the Last Glacial Period appear presently in the high part of mountains. The karstic depressions, on the other hand, which are found in the Taurus Mountains is rich in terms of endemic and relic plant species and communities such as Quercus vulcanica and humid plant species growing in the Euro-Siberian region. Because the thick soil cover which is found the inside of the small karstic depression forms suitable condition for the growth of hydrophytic plants. There is a considerable difference in the plant ommunities between on the slopes facing north and south of the Northern Anatolian Mountains. The deciduous forest is common on the lower part of the northern slopes of the Mountain, and the coniferous forest mostly belonging to Euro-Siberian phytogeographic region appears on the upper part of the Northern Anatolian Mountains. But the southern slopes and the tectonic corridors of same mountains are the main occurrence area of the dry forest mostly composed of Quercus sp. and xerophytic Mediterranean plants. The mountain ranges exceeding over 1000 m elevation in the same climatic region cause vertical zonation in terms of ecological conditions. For this reason three orobiomes are found along the vertical distance, in general. For instance, the lower belt of Taurus Mountains extending between seashore and 1000/1200 m is main spreading areas of typical Mediterranean plants composed of red pine (Pinus brutia) and maquis. Second belt which is found between 1200-2000 m is the main occurrence areas of the cedar (Cedrus libani), Taurus fi r (Abies cilicica) and black pine (Pinus nigra). Third belt corresponds to the sub alpine zone in which some alpine and steppes plants grow. The tectonic corridors occurring amongst the mountain ranges produce the semiarid conditions in which some xerophytes are common. Shortly, the Anatolian mountainous areas are very rich in terms of the plant species and communities due to the fact that different habitat which are found both horizontahorizontal and vertical direction. The formation of rich biodiversity is related to the existence of rugged mountainous areas.
