The vegetation type which is found only in the Northern Hemisphere is the "Tundra vegetation". Tundra vegetation is a type of vegetation that is found in the arctic and subarctic regions of the Northern Hemisphere, where the climate is too cold for trees to grow. Instead, the vegetation is dominated by low-growing shrubs, mosses, and lichens. Tundra vegetation is characterized by its ability to survive in extremely cold and harsh environments, and it is an important habitat for a variety of animals, including caribou, reindeer, and polar bears.
