Cycle The Carbon Cactus is found in the
Atacama Deserts. Gobi Desert Atacama Desert Great Basin Antarctica Turkestan Namib Desert The key distinction between a cold desert and what we would normally think of as a hot, arid desert, is the cold desert's climate. Cold deserts have long, cold winters with high precipitation, typically an abundance of snowfall. Summers have moderate temperatures, are generally moist, and have a fair amount of rainfall as well. The Breakdown Under 40° F in the winter
70° F to 80° F in the summer
15 to 26 cm of rainfall The Atacama Cold Desert, which is on the coasts of Chile and Peru is also has Humboldt Penguins and Llamas Cold deserts are often home to small rodents, such as the Kangaroo Rat that lives in North America and the Jeboa of the Gobi and Takla Makan deserts. Other small rodents include gerbils, pocket mice, and golden moles. Lizards are also common, the Iguana Chilena lives in the Antacama Desert and Monitor Lizards live in the Iranian Desert. Snow Leopards and Wolfs live in the Gobi Desert. The Gobi Desert covers parts of northern and northwestern China, and of southern Mongolia The bactrian camel and the gazell live in the Takla Makan desert. The Takla Makan Desert is in parts of Northwest China. Grazing can be a problem in cold deserts. Animals can trample the roots of young plants and unearth them from the soil. Repeated grazing in an area can also compact soil, degrading it. Tourism has had an adverse effect on cold deserts as well. Hikers can leave behind trash that pollutes the environment and can often disturb the animals living in a frequented area. Besides humans, natural disturbances are also changing cold deserts. The melting of glaciers and the resulting water can be a source of erosion and land loss. Earthquakes can also disrupt animals and the environment in cold deserts in prone areas. Various types of grasses are common in most cold deserts.
Bunch grass can be found in the Nambi desert of the coasts of Southwestern Africa, and Atacama Most Cold deserts have some type of shrubs. Examples include the sagebrush of the Great Bason Cold desert and the alhagi shrub found in the Turkestan desert. The Turkestan desert is in parts of the Middle East and Southwestern Russia Trees are also common in cold deserts. Pistachio trees can be found in the Iranian desert. Other trees found in various cold deserts are tamaruga trees, and the saxaul tree. Welwitschia lives in the Nambi Desert.
