The ecoregion stretches in patches on the main Tian Shan mountain ridge, across approximately 2,000 km from western Kyrgyzstan to eastern Xinjiang Province in China. The conifer forest belt is found on north-facing slopes, at altitudes from a minimum of 1,500 meters (below which it is too dry to support conifers) to a maximum of 2,700 meters (above which it is too cold). The disconnected components of the ecoregion tend to be elongated along ridges that average 4,000 meters in height, with one of the larger sections wrapping around Lake Issyk-Kul. In general, the landscape below the forest belt is steppe, and above is alpine meadow with occasional dwarf junipers.
