In addition, the polar regions spend a large part of the year in darkness. Tundras are most common in the Low Arctic, and polar barrens are dominant in the High Arctic. They often have spines that protect their leaves and stems from being eaten by herbivores looking for food and moisture. Identifying features of the small desert tree are its tall branches, fleshy stems, and yellow flowers. and thermokarst lakes (formed from melting permafrost).

Even though most algae and fungi are no longer classified within the plant kingdom, they are often still included in discussions of plant life. The flora and fauna of these islands are poorly developed, largely because of their isolation from potential sources of terrestrial biota. In some areas, notably west of Hudson Bay, a similar environment results in tundra grassland. The showy flowers measure 3 to 4 (7.5 10 cm) long. Photo courtesy of DonGato, Flickr.
