Effect of floodwater irrigation on carbon sequestration potential of Helianthemum lippii (L.) Pers., Dendrostellera lessertii Van Tiegh. And Artemisia sieberi Besser in the Gareh Bygone plain: A case study

Climate change is one of the most important challenges in sustainable development which has negative effect on terrestrial and aquatic ecosystems. The main agent of this phenomenon is CO2 accumulation in atmosphere. Carbon sequestration in plant biomass by inexpensive and multi-purpose methods in arid and semi arid rangelands is a suitable method of facing this phenomenon. In this study, in order to investigate the effect of floodwater irrigation on rangelands on carbon sequestration of shrub species, some parts of Gareh Bygone rangelands was selected. After determining the key area, dominant species of shrubs in both water spreading and control area were selected. In both areas, the amount of aboveground and underground biomass of species was estimated according by determining the wet weight of each organ. Moreover, the organic C of each organ of different species was determined. The result of comparing data average by independent sample t-test represents that despite of different response of studied species carbon sequestration to floodwater irrigation, carbon sequestration by dominant species shrubs in water spreading area with the average of 100.09 kg haʹ1 is about twice as much as carbon sequestration of those species in control area with the average of 50.63 kg haʹ1.
