What Is the Polar Bear's Biome?

The polar bear's natural habitat is located in the arctic tundra biome. This ecoregion is characterized by exceedingly low temperatures, short growing periods, minimal precipitation, sparse vegetation and the presence of permafrost.

The tundra biome is classified into two types: arctic and alpine. The arctic tundra biome is found throughout the northernmost coastal regions of Asia, North America and Europe, including some areas in Greenland.

Animals that live in the arctic tundra have certain adaptations that enable them to survive the biome's harsh environmental conditions. For example, the thick fur of polar bears provides adequate insulation to withstand the extremely cold climate. Aside from polar bears, the arctic tundra is also home to lemmings, voles, arctic foxes, wolves, caribou and several species of migratory birds.
