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. Taiga forests cover about 47% of Sakha and almost 90% of the cover is larch. Larch trees dominate in the north and stands of fir and pine begin to appear in the south.

Below the tundra is the vast taiga forest region. In the southern part of the tundra belt, scattered stands of dwarf Siberian pine and larch grow along the rivers.

Arctic and subarctic tundra define the middle region, where lichen and moss grow as great green carpets and are favorite pastures for reindeer. 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. Sakha can be divided into three great vegetation belts. After Nunavut was separated from Canada's Northwest Territories, 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 2). New Siberian Islands are a part of the republic's territory. These waters, the coldest and iciest of all seas in the Northern Hemisphere, are covered by ice for 9–10 months of the year. Sakha stretches to the Henrietta Island in the far north and is washed by the Laptev and Eastern Siberian Seas of the Arctic Ocean. Highest point: Peak Pobeda (3,003 m), Mus-Khaya Mountain Peak (2959 m or 3,011 m).water: Arctic Ocean (including Laptev Sea and Eastern Siberian Sea) (N).internal: Chukotka Autonomous Okrug (660 km)(E), Magadan Oblast (1520 km)(E/SE), Khabarovsk Krai (2130 km)(SE), Amur Oblast (S), Zabaykalsky Krai (S), Irkutsk Oblast (S/SW), Krasnoyarsk Krai (W).Geography įauna of the Sakha Republic: Ross's gull, the Siberian crane, polar bear, horse and reindeer. It is pronounced as Haka by the Dolgans, whose language is either a dialect or a close relative of the Yakut language. The self-designation Sakha is probably of the same origin (* jaqa > Sakha following regular sound changes in the course of development of the Yakut language) as the Evenk and Yukaghir exonyms for the Yakuts. The Yukaghirs, another neighboring people in Siberia, use the exonym yoqol ~ yoqod- ~ yoqon- ( Tundra Yukaghir) or yaqal ~ yaqad- ~ yaqan- ( Kolyma Yukaghir). This was in turn picked up by the Russians. The exonym Yakut comes from the Evenk term Yаkо (also yoqo, ñoqa, or ñoka), which was the term the Evenks used to describe the Sakha. The Soviet era saw the migration of many Slavs, specifically Russians and Ukrainians, into the area. Yakutia saw some of the last battles of the Russian Civil War, and the Bolshevik authorities re-organized Yakutsk Oblast into the autonomous Yakut ASSR in 1922. While the initial period following the Russian conquest saw the Sakha population drop by 70%, the Imperial period also saw the expansion of the native Yakuts from the middle Lena along the Vilyuy River to the north and the east displacing other indigenous groups. The Russians colonised and incorporated the area as Yakutsk Oblast into the Tsardom of Russia in the early-mid 17th century, obliging the indigenous peoples of the area to pay fur tribute. Migrating from the area around Lake Baikal, the Turkic Sakha people first settled along the middle Lena river sometime between the 9th and 16th centuries, likely in several waves, bringing the pastoral economic system of Central Asia with them. Sakha was first home to hunting-gathering and reindeer herding Tungusic and Paleosiberian peoples such as the Evenks and Yukaghir. The hypercontinental tendencies also result in warm summers for much of the republic. The republic has a reputation for an extreme and severe climate, with the lowest temperatures in the Northern Hemisphere being recorded in Verkhoyansk and Oymyakon, and regular winter averages commonly dipping below −35 ☌ (−31 ☏) in Yakutsk. Yakutsk, which is the world's coldest major city, is its capital and largest city.

Sakha comprises half of the area of its governing Far Eastern Federal District, and is the world's largest country subdivision, covering over 3,083,523 square kilometers (1,190,555 sq mi). Sakha, officially the Republic of Sakha (Yakutia), is a republic of Russia, in the Russian Far East, along the Arctic Ocean, with a population of roughly 1 million.
