Yang H, Sun J, Xu C, Zhang J, Chai J, Jiao T, Yu X. (2019) Hoof pressure and trampling intensity of yaks are higher than those of Tibetan sheep in a Tianzhu alpine meadow. The Rangeland Journal 41, 125–133. https://doi.org/10.1071/RJ18073 Download citation file: Trampling by grazing animals exerts a comprehensive and serious effect on grassland vegetation and soil. In order to compare the trampling of yaks and Tibetan sheep under different grazing intensities, we examined the hoof pressure and trampling intensity (based on trampling area and hoof-print count) of white yaks (Poephagus grunniens) and Tibetan sheep (Ovis ammon) in an alpine meadow of Tianzhu County, Gansu Province, China, under conditions where either grazing area or livestock number were controlled. The average areas trampled by yaks and Tibetan sheep were 39.2 and 21.6 cm2 respectively. The average hoof pressure of yaks and Tibetan sheep were 6.89 and 3.13 kg cm–2 respectively. The yak-to-sheep ratio of the average are
