There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
As an indicator biome, the tundra is a crucial part of the whole global climate system and can help predict the changes the rest of the world will face. The Earth depends on regulating mechanisms and air circulation patterns the tundra provides to keep climates steady worldwide.

As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
Geographical locations where the taiga biome is found. Compared to the tundra, boreal forest has a longer and warmer growing season and supports increased species diversity, canopy height, vegetation density, and biomass. Unlike the tundra, which is characterized by a lack of trees and tall vegetation, [45] boreal forests support a number of ...
