Alpine steppe

Alpine-steppes are unique ecosystems found throughout the world, especially in Asia, where they make up 38.9% of the total Tibetan plateau grassland's area.

[3] In addition, upwards to 80% of this falls between the months of May and September, causing the climate to be arid or semi-arid, making the environment much harsher for plant and livestock life.

[6] Changes in vegetation have been used recently as an indicator of grassland degradation in the Tibetan Plateau, along with land desertification and decreased overall productivity.

[2] While these measures are certainly a step in the right direction as far as sustainability legislation, they have not been shown to have a very strong effect on the above ground net primary productivity (ANPP).

The addition of dung to the soils of this region in a laboratory setting resulted in increased availability of ammonia for plants (their primary nitrogen source).

The purpose of this protective fencing is to prevent the grazing activity of large livestock, like sheep, yaks, and goats, in an attempt to restore the degraded biomass, and maintain ecosystem function.

[1] The overall goal is to improve ecosystem carbon, nitrogen, and phosphorus storage, by increasing both vegetation and soil pools of these elements.

[1] However this effect was minor, and not enough to compensate for the considerable loss of carbon, nitrogen, and phosphorus pools from the soil surface layer.

[10] The alpine-steppe in this area has less than 20% vegetation coverage, which consists mainly of Stipa purpurea, Artemisia capillaris, and Rhodiola rotundaia assemblages.

[10] The highest vegetation carbon pool can be found in August, and nitrogen and phosphorus concentrations in the area exhibit seasonal variations throughout the growing period.
