Geography

Sakha stretches to the Henrietta Island in the far north and is washed by the Laptev and Eastern Siberian Seas of the Arctic Ocean. These waters, the coldest and iciest of all seas in the Northern Hemisphere, are covered by ice for 9–10 months of the year. New Siberian Islands are a part of the republic's territory. After Nunavut was separated from Canada's Northwest Territories in 1999, Sakha became the largest subnational entity (statoid) in the world, with an area of 3,083,523 square kilometers (1,190,555 sq mi), slightly smaller than the territory of India (3.3 million km), but still slightly larger than Argentina.

Sakha can be divided into three great vegetation belts. About 40% of Sakha lies above the Arctic Circle and all of it is covered by permafrost which greatly influences the region's ecology and limits forests in the southern region. Arctic and subarctic tundra define the middle region, where lichen and moss grow as great green carpets and are favorite pastures for reindeer. In the southern part of the tundra belt, scattered stands of dwarf Siberian pine and larch grow along the rivers. Below the tundra is the vast taiga forest region. Larch trees dominate in the north and stands of fir and pine begin to appear in the south. Taiga forests cover about 47% of Sakha and almost 90% of the cover is larch.

The Sakha Republic is the site of Pleistocene Park, a project directed at recreating Pleistocene tundra grasslands by stimulating the growth of grass with the introduction of animals which thrived in the region during the late Pleistocene – early Holocene period.
