As a part of an ecological research project on wild animals in the Sarychat-Ertash State Reserve, we surveyed the alpine vegetation near the forest line (at an elevation from ca.3,000 to 3,200 m)in the Ertash Valley of the northern Tian Shan mountains of the Kyrgyz Republic. Horses and sheep are kept as livestock in the area and Marco-Polo sheep (argali) and wolves inhabit the region, but information on wildlife, weather conditions and inhabitants’ livelihood is hard to obtain. In May 2011, we established 5 transverse transects across a river to describe a cross-sectional view of the vegetation. As a result, the 8 woody species identified belonged to 6 families and all exhibited shrubby forms. Shrubby cinquefoil (Potentilla fruticosa) was distributed throughout the survey area, and thorny Caragana jubata was interspersed locally. The number of woody species increased significantly at higher elevations. We discuss the reason for the unexpected increase in number of species with increasing elevation.
