A controlled trampling study was conducted in Nigde-Aladag Mountains Natural Park, a popular destination for recreational activity, to explore the short-term impacts of different trampling intensities (0, 25, 75, 200, 500 passes) on soil and vegetation. Short-term recreational trampling activities do not significantly affect most of the topsoil properties. The most affected soil properties are total porosity and soil penetration resistance. The soil penetration resistance of topsoils significantly increased after 200 and 500 pass plots compared to the control plots. The soil penetration resistance, which was 3.78 kg/cm2 in the topsoil of control plots, reached 6.06 kg/cm2 after 500 passes. Total porosity of topsoils in 500 passes was significantly different from the control plots. While the total porosity was 52.38% in the topsoil of control plots, it decreased to 41.41% after 500 passes. In the short-term, the other soil properties remain the same in general. The relative vegetation cover and relative vegetation height also significantly decrease after trampling. The relative vegetation cover, which declined to 84% after 25 passes, decreased to 67% after 500 passes. Relative vegetation height was 69% after 25 passes and decreased to 27% after 500 passes. The significant decrease in total vegetation cover was observed after 200 and 500 passes. Compared to the control lane, vegetation height was significantly different from the 25, 75, 200 and 500 passes.
