S.G. REYNOLDS The Tibetan Steppe 313 Plate 8.4 Elymus nutans . litwinowii , Helictotrichon tibeticum , Brachypodium sylvaticum , Stipa aliena , Festuca rubra , F. ovina and Deschampsia cespitosa . Large areas of productive pasture are dominated by Elymus nutans (Plate 8.4) in the alpine meadow, especially in northwestern Sichuan, southwestern Gansu and eastern Qinghai. In swampy depressions in the alpine meadow there is hummock vegetation dominated by Kobresia spp. (30-cm tall K. royleana and K. schoenoides). Shrub communities of plants such as Salix spp. , Caragana jubata , Potentilla fruticosa and Rhododendron spp. are common on northern aspects in alpine meadow. Most Tibetan pastoralists and their stock are found in the alpine meadow region. Livestock densities can be high; in eastern Qinghai, stocking rates are 28-70 animals/km 2 , and heavy grazing and trampling, together with solifluction, have disturbed the sod layer, causing extensive rangeland degradation (Schaller, 1998). Alpine steppe The alpine steppe comprises almost 29 percent of the area and is found between 3 500 and 4 600 m in the central and western steppe. Unlike the alpine meadow , there is no sod layer, and the soil is often gravel and coarse sandy loam; it is a variant of the temperate steppe under the cold conditions of the Tibetan plateau (Huang, 1987). Grasses of the genus Stipa dominate, often accompanied by cushion plants, with S. purpurea and S. subsessiliflora as the dominant grasses. Associated species are mainly xeric and meso-xeric grasses: Poa alpina (Plate 8.5), P. crymophila , P. dolichachyra , Roegneria nutans , R. thoroldiana , Agropyron cristatum , Stipa aliena , Orinus thoroldii , Calamagrostis spp. , Festuca

Shrubs include Potentilla fruticosa , Ajana spp. , Artemisia spp. and Ceratoides compacta . Forbs include Potentilla bifurca , Dracocephalum heterophyllum , Heteropappus altaicus , Leontopodium spp. , Pedicularis spp. , Allium spp. , Oxytropis spp. and Astragalus spp. , with the cushion plants Androsace tapete , Arenaria musciformis and Oxytropis microphylla .
