Alpine tundra
In physical geography, an alpine tundra, alpine habitat, alpine zone, or alpine biome is in the mountains.  The alpine habitat is too high up for trees to grow but not so high that the snow and ice never melt.  There are alpine places all over the Earth.  There are tropical alpine places and arctic alpine places.  Many alpine places are 3000 meters (10,000 feet) above sea level, but they can be higher or lower depending on how far from the equator and ocean they are.
