The Pyasina (Russian : Пясина) is a river in Krasnoyarsk Krai, Russia. The river is 818 kilometres (508 mi) long, and its basin covers 182,000 square kilometres (70,000 sq mi). [1] The Pyasina River originates in Lake Pyasino and flows into the Pyasino Gulf of the Kara Sea. There are more than 60,000 lakes in the basin of the Pyasina covering a total area of 10,450 square kilometres (4,030 sq mi). The river freezes up in late September or early October and stays under the ice until June. It is connected to the river Chetyrekh through its right distributary Staritsa.
The Dvina merchant Kondratiy Kurochkin reached the mouth of the Pyasina in 1610. [2] In 1614, an ostrog was built on the river to collect yasak from the natives. [2] In 1935, before the Dudinka-Norilsk railway had been built, the river Pyasina and Lake Pyasino were used to deliver cargo to the site of the future city of Norilsk. [3]
The calving grounds of the Taimyr reindeer herd, a migrating tundra reindeer (R.t. sibiricus), the largest reindeer herd in the world, [4] [5] is along the right bank of the Pyasina and at the bend of the middle flow of the Agapa. [6] : 336
The Anadyr is a river in the far northeast of Siberia which flows into the Gulf of Anadyr of the Bering Sea and drains much of the interior of Chukotka Autonomous Okrug. Its basin corresponds to the Anadyrsky District of Chukotka.
The Yenisey is the fifth-longest river system in the world, and the largest to drain into the Arctic Ocean.
The reindeer or caribou is a species of deer with circumpolar distribution, native to Arctic, subarctic, tundra, boreal, and mountainous regions of Northern Europe, Siberia, and North America. It is the only representative of the genus Rangifer. More recent studies suggest the splitting of reindeer and caribou into six distinct species over their range.
The Nganasans are a Uralic people of the Samoyedic branch native to the Taymyr Peninsula in north Siberia. In the Russian Federation, they are recognized as one of the indigenous peoples of the Russian North. They reside primarily in the settlements of Ust-Avam, Volochanka, and Novaya in the Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai, with smaller populations residing in the towns of Dudinka and Norilsk as well.
The Yana is a river in Sakha in Russia, located between the Lena to the west and the Indigirka to the east.
The migratory woodland caribou refers to two herds of Rangifer tarandus that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or woodland caribou that live in Nunavik, Quebec, and Labrador: the Leaf River caribou herd (LRCH) and the George River caribou herd (GRCH) south of Ungava Bay. Rangifer tarandus caribou is further divided into three ecotypes: the migratory barren-ground ecotype, the mountain ecotype or woodland (montane) and the forest-dwelling ecotype. According to researchers, the "George River herd which morphologically and genetically belong to the woodland caribou subspecies, at one time represented the largest caribou herd in the world and migrating thousands of kilometers from boreal forest to open tundra, where most females calve within a three-week period. This behaviour is more like barren-ground caribou subspecies." They argued that "understanding ecotype in relation to existing ecological constraints and releases may be more important than the taxonomic relationships between populations." The migratory George River caribou herd travel thousands of kilometres moving from wintering grounds to calving grounds near the Inuit hamlet of Kangiqsualujjuaq, Nunavik. In Nunavik and Labrador, the caribou population varies considerably with their numbers peaking in the later decades of each of the 18th, 19th and 20th centuries. In 1984, about 10,000 caribou of the George River herd drowned during their bi-annual crossing of the Caniapiscau River during the James Bay Hydro Project flooding operation. The most recent decline at the turn of the 20th century caused much hardship for the Inuit and Cree communities of Nunavik, who hunt them for subsistence.
Lake Pyasino is a large freshwater lake in Krasnoyarsk Krai, north-central part of Russia. It is located at 69.67°N 87.86°E and has an area of 735 km2. Many rivers empty into the lake, including the Ambarnaya. Water from the lake emerges as the river Pyasina. Pyasino freezes up in October and stays icebound until June.
The Chetyrekh is a river in Krasnoyarsk Krai, Russia. Its source is in the Byrranga Mountains.

Reindeer in Russia include tundra and forest reindeer and are subspecies of Rangifer tarandus. Tundra reindeer include the Novaya Zemlya (R.t.pearsoni) and Sápmi subspecies and the Siberian tundra reindeer.
Taymyr Nature Reserve is a Russian 'zapovednik' located in the northern lowlands of Siberia, on the Taimyr Peninsula, and on the coast of the Laptev Sea of the Arctic Ocean. The reserve includes the most northern forest of Dahurian larch in the world, and also the most northern mainland mountain range in the world. The protected area was established to protect the breeding grounds of the Red-breasted goose as well as the summer residences of wild reindeer and the biodiversity of the Lake Taymyr. The reserve is situated about 120 km east of the town of Norilsk, and 3,000 km northeast of Moscow, in the Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai. In 1995, the site was designated a UNESCO MAB Reserve. The reserve was formally established in 1979, and covers an area of 1,781,928 ha (6,880.06 sq mi).
The Rassokha is a river in the northeastern part of Yakutia, Russia. It is the major tributary of the Alazeya.
The reindeer is a widespread and numerous species in the northern Holarctic, being present in both tundra and taiga. Originally, the reindeer was found in Scandinavia, eastern Europe, Russia, Mongolia, and northern China north of the 50th latitude. In North America, it was found in Canada, Alaska, and the northern contiguous USA from Washington to Maine. In the 19th century, it was apparently still present in southern Idaho. It also occurred naturally on Sakhalin, Greenland, and probably even in historical times in Ireland.
