omparison of aerial and underground carbon sequestration potential of Stipa barbata in Fasham Pastures, Iran
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 4, Issue 5
Abstract
Rangelands play an important role in the carbon cycle. Although their ability to absorb CO2 from the atmosphere could help offset human influence on climate change, there are many other ecological benefits associated with sequestering carbon on rangelands. Iran's rangelands have carbon sequestration capability by compatible species with the area. However, little information is available about the amount and distribution of carbon stocks in these rangelands. Fasham Ranges the infested city because of its proximity to Tehran, are very important in terms of carbon sequestration. This study aims was to compare above and underground carbon sequestration potential of a horse's mane (Stipa barbata) in Fasham pastures at two grazed and enclosured areas. In order to study the vegetation variables, the random – systematic sampling method was used. Then the plant biomass and organic carbon content in different plant organs was achieved. With the initial weight percent and organic carbon percent for above and underground biomass, conversion coefficient was calculated and by multiplying the initial biomass, carbon sequestration rate was achieved. The results showed that the average carbon sequestration in underground organs in both the grazed and enclousure is over than aboveground. There is a significant difference between the average carbon sequestration at underground organs of this species in grazed areas (12/79 kg per hectare) and enclosure (18/26 kg per hectare) (P <0.01).
