Vegetation geography of Geyve Strait and its surroundings

In this study, the distribution of vegetation in and around the Geyve Strait and the ecological factors affecting its distribution were examined. The Geyve Strait and its surroundings, which form the study area, are located within the borders of the Marmara Region, Sakarya province, Geyve district. Geyve Strait and its surroundings have ecological conditions suitable for the development of moist forest and dry forest vegetation. Humidity species such as Fagus orientalis, Castanea sativa and Tilia argentea are distributed in parts of the study area where precipitation is high, temperature conditions are favorable and there is no effective dry season. It is possible to come across Pinus brutia, one of the dry forest trees, in the southern parts of the study area, where the precipitation amounts are low. In the study area where forest formations have been destroyed, moisture shrub species and xeric shrub species are distributed. Grass vegetation in the study area is generally found as forest cover. In this study, topography, climate, management plans, stand and soil data were used and field studies were carried out. 1/25000 scale topography maps obtained from the General Command of Mapping were used as a base in the making of the maps belonging to the study area. The maps prepared for the study was used in the ArcGIS 10.8 program. In order to examine the study in more detail, CorelDRAW 2021 program was used in the production of plant sections. Due to the special ecological conditions of the Geyve Strait and its surroundings, there are dense vegetation and different plant species in the area. For this reason, it is important to protect the site in terms of the sustainability of the vegetation.
