The Tian Shan, or "Celestial Mountains," is a large, isolated mountain range surrounded by desert basins. Here, dense coniferous forests and open meadows stretch between high peaks and glaciers and low desert basins.
More than 2,500 plant species thrive in this diverse region. Because of the elevation, these mountains receive more precipitation and have a greater range of climate zones than other desert regions. The Tian Shan is more than 1,500 miles (2,500 km) long, with ridges reaching about 13,000 feet (4,000 m) high and some peaks over 24,000 feet (7,400 m). The Gongliu Yunshan and Tuomu’er Feng Nature Reserves protect some areas.
Forest cover is generally restricted to north-facing slopes in this ecoregion. Where forests don’t grow, steppe or meadow vegetation thrives. At higher elevations spruce dominates, but mountain ash, willow, and several birch species are also prevalent. At lower elevations, spruce and aspen are the dominant tree species. Grasses and forbs also live in the understory of the forest, where carpets of moss thrive in low light conditions. The ecoregion's top predator is the endangered snow leopard. Wild sheep and goats, such as the ibex and Tian Shan argali, are the most common prey for snow leopards in this ecoregion.
Overgrazing at the higher elevations threatens this area. Local residents shoot animals for their meat and other parts that they can sell. Snow leopards are killed because they sometimes eat livestock, and it is possible that this rare creature no longer survives in the ecoregion. Conservationists would like to see more of these forests, meadows, and mountains protected in the future. For more information on this ecoregion, go to the World Wildlife Fund Scientific Report.
