Rangelands comprise the large parts of Iran as a steppic area. Ghazvin, as area index of steppic area, was selected under three sites including long-term exclosure, medium-term exclosure, and grazable area due to the capability of carbon dioxide’s sequestration of dominated species. Canopy cover’s percentage of two dominated species (Salsola laricina and Poa sinaica) was determined via establishing of random 1 square meter plot. The sampling of above and below ground biomass style was obtained by complete random. After determination of ash percentage in the laboratory; conversion ratio of plant biomass to organic carbon was calculated by ignition method. Results of the paired t-test showed that the amount of carbon sequestration in above ground and underground biomass of Salsola laricina and Poa sinaica is different in three regions. It, of course, has not any difference between under and surface ground’s biomass of Salsola laricina in long-term exclosure. The independent t-test results indicate differences between underground biomass corresponding each other in the studied sites. Carbon sequestration in the Poa sinaica was totally more than Salsola laricina Altogether, the average sequestration of the long-term exclosure was 5.842gr/m², the medium-term exclosure was 4.115gr/m², and grazable area was 5.975gr/m² so that there is not valuable statistical difference in terms of total amount of carbon sequestration to three sites.
