Alpine tundra occurs in mountains worldwide. It transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as Krummholz. With increasing elevation, it ends at the snow line where snow and ice persist through summer, also known as the Nival Zone.
The tundra is characterized by a harsh, frost-laden landscape with negative temperatures, a lack of precipitation and nutrients, and extremely short seasons. In the winter it is cold and dark, and in the summer when the snow and the top layer of permafrost melt, it is very soggy and the tundra is covered with marshes, lakes, bogs, and streams.

Vaccinium vitis-idaea keeps its leaves all winter even in the coldest years, unusual for a broad-leaved plant, though in its natural habitat it is usually protected from severe cold by snow cover. It is extremely hardy, tolerating temperatures as low as −50 °F (−45 °C) or lower, but grows poorly where summers are hot.
