This description fits the tundra, a biome found in the Arctic and Antarctica. Here's why:

* Treeless plain: Tundras are characterized by the absence of trees due to the harsh climate.

* Arctic or Antarctic: These are the primary locations of tundra biomes.

* Very low winter temperatures: Tundras experience extremely cold winters with temperatures often falling below freezing.
