Other definitions use the term to apply only to hot and temperate deserts, a restriction followed in this account. cold desert, any large arid area of land that typically receives scant amounts of annual precipitation, which occurs mainly in the form of snow or fog. Some cold deserts have a short season of above-freezing temperatures. For example, it is thought that the saltbush or chenopod family of plants reached Australia in this way, initially colonizing coastal habitats and later spreading into the inland deserts.

This is due in part to intrinsic physiologic characteristics in some widespread desert families that preadapt the plants to an arid environment; it also is a result of plant migration occurring through chance seed dispersal among desert regions. Most of the vegetation here is made up of shrubs and low-lying plants, and the vertebrate fauna includes guanacos, rheas, burrowing owls, pumas, and gray foxes.

Shrubs and grasses are the main types of vegetation, and most plants and other organisms have adaptations that enable them to survive the dry, frigid conditions. Besides being dry, deserts are also windy, and that increases the evaporation rate. Rock ptarmigans eat flowers, berries, buds, leaves, twigs and other vegetation. The desert biome covers about one-fifth of Earth's surface. Bacteria, algae, mosses, lichens, and microorganisms manage to survive hereincluding psychrophiles, which are extremophile microorganisms that require temperatures below freezing in order to survive; psychrophiles thrive in temperatures as low as 20 C (4 F).
