Distinctiveness (1=highest,4=lowest): N/A
These areas are covered by permanent glaciers and unvegetated rock. These areas are present at the top of high peaks, although large glaciers may flow to the sea near the coast.
Conservation Status (1=most endangered, 5=most
Because of lack of living communities, species in these areas are not threatened, although global climate change is resulting in the decrease of glaciated areas.*
