Nature is never easy to understand, and the tundra proves it. Three types of tundra exist: antarctic, alpine, and arctic. The main difference between these types of tundra is their location on the earth. But they share many characteristics like cold, dry weather, which is why they’re all called Tundra.
Imagine a scene by the mountain with sly rodents, birds, and large mammals moving about the area. That’s what you’ll most likely see in the alpine tundra – “alpine” meaning mountains.
This type of tundra is mostly in the northern hemisphere. It includes landscapes from mountain ranges into stretches of flat, cold desert. Only when you go farther south to the subalpine terrain will you reach the boundary where trees start growing (also known as the “timberline”).
In warmer weather of the alpine tundra, the situation improves and the landscape transforms into a sea of color where tundra-adapted plants and animals thrive. The alpine tundra doesn’t have permafrost, so soil can better absorb water. Because of that, alpine tundra is livable for plants and animals, like marmot, mountain goat, sheep, and upland ground birds. These animals and others migrate through this area over the course of the year. Seasonal climate changes make a world of difference to the tundra’s occupants.
But don’t think the alpine tundra is only in far-off places. Around the world, alpine tundra can also be found on mountain tops. At very high elevations, mountain peaks can be consistently cold and dry with hardly any vegetation. Climate like that is similar to alpine tundra regions. These patches of tundra-like environments can be found on mountains in places like Norway and even Arizona.
