Sayan Alpine meadows and tundra

The Sayan Alpine meadows and tundra ecoregion (WWF ID:PA1016) is an ecoregion that covers the high areas of the Sayan mountains above the treeline, between the Altai Mountains in the west and Lake Baikal in the east. The area is remote and protects diverse species of alpine flora and fauna. It has an area of 846,149 square kilometres (326,700 sq mi).[1] [2]

Location and description

The ecoregions covers the terrain above the treeline in the high ranges of the Western Sayan Mountains, in the Altai Republic, and the Eastern Sayan Mountains, reaching almost to Irkutsk. There are also some high areas in northern Mongolia. This ecoregion is characterized by glacially-carved valleys with an upland mosaic landscape of alpine meadows.

Climate

The region has a Humid continental climate - cool summer subtype (Koppen classification Dfc). 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 22 °C (72 °F). Mean precipitation is about 500 mm/year. The mean temperature at the center of the ecoregion is −29.5 °C (−21.1 °F) in January, and 13 °C (55 °F) in July.[3]

Flora and fauna

Both plant and animal diversity is high, as the area is relatively protected by its remoteness and by its position at the meeting places of different ecological zones. From treeline up to the barren rock zone, alpine meadows and associated species predominate.

Protections

There are two significant nationally protected area that reach into this ecoregion:

gollark: * now
gollark: The AP is great right know. I caught a 31G xenowyrm, great for my ultra messy lineage project.
gollark: FINALLY the Valentine's thing is over and I can get eggs I actually want in the biomes.
gollark: In other news, I've run out of my usual names and am just naming dragons after moderately obscure metal bands.
gollark: My lineage-project dragon steadfastly refuses to breed with any other ones. This is very annoying.
