Taymyr Peninsula in the context of "Yenisey River"

The Yenisey or Yenisei (/ˌjɛnɪˈseɪ/ YEN-iss-AY; Russian: Енисе́й, pronounced [jɪnʲɪˈsʲej]) is the fifth-longest river system in the world, and the largest to drain into the Arctic Ocean.

Rising in Mungaragiyn-gol in Mongolia, it follows a northerly course through Lake Baikal and the Krasnoyarsk Dam before draining into the Yenisey Gulf in the Kara Sea. The Yenisey divides the Western Siberian Plain in the west from the Central Siberian Plateau to the east; it drains a large part of central Siberia. Its delta is formed between the Gyda Peninsula and the Taymyr Peninsula.

The Nenets (Nenets: ненэй ненэче, romanized: nenəj nenəče; Russian: ненцы, romanized: nentsy), in the past also called 'Samoyeds' or 'Yuraks', are a Samoyedic ethnic group native to the Russian Arctic, in the Russian Far North. According to the latest census in 2021, there were 49,646 Nenets in the Russian Federation, most of them living in the Yamalo-Nenets Autonomous Okrug, Nenets Autonomous Okrug and Taymyrsky Dolgano-Nenetsky District stretching along the coastline of the Arctic Ocean near the Arctic Circle between Kola and Taymyr peninsulas. The Nenets people speak either the Tundra or Forest Nenets languages. In the Russian Federation they have a status of Indigenous small-numbered peoples. Today, the Nenets people face numerous challenges from the state and oil and gas companies that threaten the environment and their way of life. As a result, many cite a rise in locally based activism.

The tundra swan (Cygnus columbianus) is a small swan of the Holarctic. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick's swan (Cygnus bewickii) of the Palaearctic and the whistling swan (C. columbianus) proper of the Nearctic. Birds from eastern Russia (roughly east of the Taymyr Peninsula) are sometimes separated as the subspecies C. c. jankowskii, but this is not widely accepted as distinct, with most authors including them in C. c. bewickii.

Bewick's swan was named in 1830 by William Yarrell after the engraver Thomas Bewick, who specialised in illustrations of birds and animals. Cygnus is the Latin for "swan", and columbianus comes from the Columbia River, the type locality.

Severnaya Zemlya (Russian: Северная Земля, lit. 'Northern Land', pronounced [ˈsʲevʲɪrnəjə zʲɪmˈlʲa]) is a 37,000 km (14,000 sq mi) archipelago in the Russian high Arctic. It lies off Siberia's Taymyr Peninsula, separated from the mainland by the Vilkitsky Strait. This archipelago separates two marginal seas of the Arctic Ocean, the Kara Sea in the west and the Laptev Sea in the east.

Severnaya Zemlya was first discovered in 1913 and first charted in 1930–1932, making it the last sizeable archipelago on Earth to be discovered and mapped. Administratively, the islands form part of Russia's Krasnoyarsk Krai. In Soviet times there were a number of research stations in different locations, but currently there are no human inhabitants in Severnaya Zemlya, except for the Prima Polar Station near Cape Baranov.

Taymyrsky Dolgano-Nenetsky District (Russian: Таймы́рский Долга́но-Не́нецкий райо́н) is an administrative and municipal district (raion), one of the forty-three in Krasnoyarsk Krai, Russia. It is located in the north of the krai above the Arctic Circle on the Taymyr Peninsula and borders with Laptev and Kara Seas in the north, the Sakha Republic in the east, Evenkiysky and Turukhansky Districts in the south, and with Yamalo-Nenets Autonomous Okrug in the west. The area of the district is 879,900 square kilometers (339,700 sq mi). Its administrative center is the town of Dudinka, which accounts for 64.4% of the district's total population. The 2010 Russian census counted 34,432 people in the whole district, as opposed to 39,786 (2002 Census) in 2002, and 55,111 (1989 Soviet census) in 1989.
