Tundras are vast, treeless regions characterized by low temperatures, permafrost, and a short growing season. They are found in the Arctic and subarctic regions of North America, Europe, and Asia. Tundras are home to a variety of plant and animal species adapted to the harsh conditions, including mosses, lichens, caribou, and Arctic foxes. The landscape of tundras is dominated by grasses, sedges, and dwarf shrubs, with patches of bare rock and ice scattered throughout. The extreme climate of tundras makes them one of the most fragile ecosystems on Earth, vulnerable to the impacts of climate change and human activities.
