 In prehistoric times Scots pine, "Pinus sylvestris", was abundant in the Yenisey valley circa 6000 BC.There are also numerous bird species present in the watershed, including, for example, the hooded crow, "Corvus cornix".The Taimyr reindeer herd, a migrating tundra reindeer ("R.t. sibiricus"), the largest reindeer herd in the world, migrated to winter grazing ranges along the Yenisey.
