Alaskan tundra

The Alaskan tundra is a vast, treeless biome found in northern Alaska characterized by cold temperatures, short growing seasons, and low precipitation. Its ground is often frozen for most of the year (permafrost), supporting hardy plants like mosses, grasses, and shrubs. The environment hosts specially adapted animals such as caribou, polar bears, and Arctic foxes. Despite its extreme conditions, the tundra plays a vital role in Earth's climate system and serves as a sensitive indicator of environmental changes like global warming. It is a unique, fragile ecosystem with significant ecological and cultural importance.
