Prairie soil is also useful for carbon sequestration. [15] Carbon dioxide is a heat trapping gas, and 40% of it is produced by humans and remains in the atmosphere thus worsening the effects of global warming. [16] Prairie grass collects this carbon from the atmosphere through photosynthesis and stores it in its soil.
The shortgrass prairie consists of different varieties of vegetation. Notably abundant grasses are blue grama (Bouteloua gracilis), sod-forming grass, and buffalo grass (Bouteloua dactyloides). Less prevalent is galleta grass (Hilaria). These grasses are native to the shortgrass prairie and therefore are drought and grazing resistant.
The deep root systems of prairie grasses absorb the abundant water that comes with the rainy season, reducing runoff, flooding and erosion. Wells made by roots trap water and act as sponges that ...
