Determination of vegetation structure of the Çatoluk forest rangeland in Isparta province

Abstract

In this study, which was carried out in Çatoluk forest rangeland located within the borders of the Aksu district of Isparta province during the vegetation period of 2013, the characteristics of the vegetation and the general features of the soil of the rangeland area in the forest were examined. In addition to examining plant species, plant-covered area, botanical composition, aboveground biomass, belowground biomass, grazing capacity and rangeland condition in the study area, some general characteristics of the soil have also been determined. The texture class of the study area was determined to be clay loam. The average bulk density was determined to be 1.196 g/cm3, pH value to be 7.35 as slightly alkaline, lime content to be 5.09 % as medium lime, organic matter content to be 5.33% as moderate level, salinity value to be 0.41 dS/m as nonsaline. The vegetation of the study area was examined and 127 taxa belonging to 33 families were identified in the rangeland area. The mean value of the plant-covered area in the rangeland was determined to be 42.6%. Also, the botanical composition of the rangeland area consists of 52.44 % Poaceae, 18.04 % Fabaceae, and 29.52 % other species. The average aboveground biomass of the rangeland area was determined to be 331.20 kg/da and the average belowground biomass was determined to be 398.80 kg/da. The grazing capacity and the rangeland condition were found to be 184 animal units and medium, respectively. Based on the results of the research, it has been determined that there is an intensive grazing pressure on the forest rangeland and the vegetation in the rangeland area has been destroyed.
