Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears. These animals have been endangered due to overhunting, an infestation of disease, loss of diet and habitat due to climate change, and human destructive activities, such as searches for natural gas and oil, mining, and road building.

Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...

Large regions of alpine tundra occur in the North American Cordillera and parts of the northern Appalachian Mountains in North America, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, the Eastern ...
The deer mice native to Andes highlands (up to 3,000 m (9,800 ft)) are found to have relatively low hemoglobin content. [41] Measurement of food intake, gut mass, and cardiopulmonary organ mass indicated proportional increases in mice living at high altitudes, which in turn show that life at high altitudes demands higher levels of energy.

Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. [2] It has a number of unique adaptations to its habitat and lifestyle, which are quite distinct from other extant owls. [7] One of the largest species of owl, it is the only owl with mainly white plumage. [6]
