Abstract: Yak (Bos grunniens) are commonly grazed on the alpine rangeland (3970 to 4160 m above sea level) of Yushu, southern Qinghai, China. The rangeland, comprising our research site, experiences a typical continental climate with a mean annual temperature of 4.1°C and annual precipitation of 350 mm. Aboveground herbage Dry Matter (DM) was found to vary among sampling locations, ranging from 40 to 744 g m-2 and from 88 to 501 g m-2, in 2004 and 2012, respectively. Over the previous decade from 2004 to 2012, soil pH was observed to decline to near-neutral values (pH 6.5 to 8.2), while available phosphoric acid (Av-P) increased to 36 to 100 mg kg-1. Plant coverage was positively correlated (p<0.05) with soil Total Nitrogen (TN) and cation content in 2012. Soil fertility of the site remained constant over the 2004-2012 period in terms of soil pH, electric conductivity, Av-P, TN and total carbon. It is, thus, concluded that the soil fertility of the research site has not been negatively affected by extensive yak-grazing over the previous decade.
