Technical Abstract: The importance of rangeland to the soil carbon pools and cycles, as well as the drivers that influence soil carbon in rangelands is presented here with emphasis on grazing, global change and drought. Experimental results will be presented addressing soil carbon responses in rangelands to grazing x climate interactions, grazing x environment interactions, additions of a legume, and how different rangelands function as a source and/or sink of carbon. Specific examples of experimental findings are presented from the northern mixed-grass prairie, shortgrass steppe, and northwestern and southwestern rangelands in the United States. Gaps are highlighted showcasing the limitation of experimental data from shrub-dominated rangelands, especially in arid regions, and the lack of entire greenhouse gas budgets for rangeland ecosystems.
