There are five basic types of Arctic wetland - bogs (lowland polygon bogs, peat mound bogs), fens, swamps, marshes, and shallow open water. Bogs and fens are the most common. Bogs usually have a surface carpet of mosses.
You may wonder how one can talk of abundant wetland when the Arctic is, in fact, a desert. Aren't deserts dry places?
Permafrost plays an important part in the formation of almost all Arctic wetlands and lakes. It remains under the wetlands at shallow depths and creates a barrier of frozen earth that prevents the water from draining away.
The other main factors are very low precipitation and cold temperatures. This restricts wetlands to poorly drained depressions or to areas where additional water is available.
