How many types of steppe climate exist?

There are two type of steppes:- An alpine-steppeis a high altitude natural grassland which receives very little rainfall. Extremely cold temperatures and sparse vegetation make the Central Tibetan Plateau Alpine Steppe ecoregion inhospitable to human communities. Not only are there no farmers in this region, but there also aren't any nomadic herders such as those found in other parts of the Tibetan plateau. Instead, this dry alpine region provides lots of undisturbed and safe habitat for great herds of wild Tibetan antelopes (chirus), blue sheep, Tibetan Gazelles, and other grazing species, as well as the predators that feed on them. The Tibetan Plateau , also known as the Qinghai-Tibetan Plateau is a vast, elevated plateau in Central Asia covering most of the Tibet Autonomous Region and Qinghai Province in China and Ladakh in Kashmir, India is one example of an alpine steppe.On an average, 25 to 50 mm of rains per year.

Shrub-steppe is a type of low rainfall natural grassland sedge and rush families can also be found here

. Shrub-steppes are distinguishable from deserts, which are too dry to support a noticeable cover of perennial grasses or other shrubs, while the shrub-steppe has sufficient moisture levels to support a cover of perennial grasses or shrubs. Rainfall is less than 7 inch per year
