Abstract:

This research was carried out on a natural rangeland area with an average elevation of 1223 meters, located within the borders of Tokmacık village in Yalvaç district of Isparta province. In the study carried out in the vegetation period of 2019, the area covered with vegetation, botanical composition, plant species in the rangeland, above-ground and below-ground biomass, rangeland condition and grazing capacity of the rangeland were determined. Transect and quadrate methods were used to determine these parameters. 125 plant taxa belonging to 28 families, were determined in Tokmacık village rangeland. The amount of the area covered with vegetation of the rangeland was determined as 41.9%. In the botanical composition, it was determined that the Poaceae was 49.80%, the Fabaceae was 20.06% and the other family was 30.14%, and the Poaceae was dominant. Grazing capacity was 52.4 animal units, and rangeland condition was determined as medium. The amount of above-ground biomass was determined as 284.6 kg/da and the amount of below-ground biomass was determined as 442.2 kg/da in the study area. According to the results obtained from the study, it is possible to talk about the destruction of vegetation in the rangeland area caused by overgrazing. This situation reveals that grazing pressure should be reduced and quality vegetation should be increased with appropriate breeding studies.
