Taimyr-Central Siberian tundra


The Taimyr-Central Siberian tundra ecoregion is an ecoregion that broadly covers the Taymyr Peninsula in the Russian Far North. It ranges from the delta of the Yenisei River in the west, across the Taymyr Peninsula and Khatanga Gulf, to the Lena River delta in the east. The region is an important area for breeding birds. It is in the Palearctic realm in the tundra biome, and is mostly located in Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai. It has an area of.

Location and description

The Taymyr Peninsula reaches into the Arctic Ocean, between the Kara Sea and the Laptev Sea in northern Siberia. Unlike much of the Arctic North, which is lowland tundra, the Taymyr Peninsula is built around highlands - the Byrranga Mountains. A notable feature of the ecoregion is Lake Taymyr, a large lake in the south of the Byrranga Mountains. The coastal plain to the north is arctic coastal desert and tundra, with terrain to the south of the mountains featuring tundra, wetlands, and thermokarst. The area is one of continual permafrost.

Climate

The region has a Humid continental climate - cool summer subtype. This climate is characterized by high variation in temperature, both daily and seasonally; with long, cold winters and short, cool summers with no averaging over. Mean precipitation is about 257 mm/year. The mean temperature at the center of the ecoregion is in January, and in July.

Flora and fauna

The flora is predominantly forbs, grasses, dwarf shrubs, and lichen. Sparse stands of willow and dwarf birch can be found in river valleys and along lake shores.
Mammals are scarce, with half being seasonal or migratory visitors. The ecoregion is the most important breeding area in Central Asia for migratory birds. in late-July and August, the total number of geese is estimated at 30,000-40,000. There are two breeding colonies of the vulnerable red-breasted goose.
