This ecoregion represents the alpine scrub and meadows of the high Himalayas, from east of the Kali Gandaki River in central Nepal, across Bhutan and Arunachal Pradesh, to northern Myanmar. The ecoregion is narrow and long, nestled between the treeline at 4,000 m and the snowline at about 5,500 m. The climate is highly seasonal. The May to September monsoon brings about 3,500 mm of rainfall, but with much drier rainshadow areas. Average summer temperature is about 20°C, dropping to below freezing in the winter. Extremely rich in plant diversity, the species include Rhododendron, and herbs such as Primula, Impatiens, Draba, Anemone, Gentiana, Meconopsis, Saxifraga, Rheum, and Viola, to name a few.
