3-3- Biomass volume, carbon sequestration, and carbon absorption in an individual tree unit
Based on all the equations described in the first four steps, the total annual gross carbon sequestration in the surveyed trees was about 1563.32 tons per year. Carbon sequestration was different between various species. The percentage of carbon sequestration by the dominant species (coniferous and broad leave) in the study area is given in Table 5.
The results revealed that plane trees had the highest carbon sequestration, accounting for 25.42% of the sequestered carbon by sampled trees within Isfahan parks. Also, the amount of tree biomass, annual carbon sequestration, and annual carbon dioxide absorption in the roots, trunk, and canopy of conifer and broad-leaved species were calculated and represented in Table5.
