In physical
geography,
tundra is a large, mostly flat, expanse where
tree growth is hindered by
permafrost. Tundras are primarily found north of the
taiga belt, and that includes northern
Russia and
Canada.
Tundra is also the name for an arctic and humid biome with
- water : low precipitation (dry)
- temperature : arctic
- soil : humid or frozen (permafrost)
- plants : lichens and mosses
- animal : very sparse (migrating animals)
The tundra is home to several peoples who are mostly nomadic reindeer herders, among them are the Saami.
Due to the harsh climate of the tundra, regions of this kind has seen little exploitation even though they are rich in natural resources such as oil and uranium. In recent time this has begun to change, and in Russia and other parts of the world the tundra is being ever more subjected to human interference.
