In this study, monthly reed sample surveys were conducted from June 2023 to January 2024 to evaluate the carbon storage and sequestration in reed colonies at an artificial salt marsh (Osaka Nanko bird sanctuary) constructed in an urban waterfront area. As a result of measuring the size, biomass, and carbon content of each part of the reeds, it was found that the dry weight of the above-ground part of the reed was highly correlated with the product of culm height and terminal stem diameter. In addition, the total carbon content according to combustion analysis was 42% in the aboveground part, 40% in the dead bodies, and 38% in the underground roots, of which 39% in the aboveground part, 60% in the dead bodies, and 45% in the underground roots are persistent components.
Based on the results of this survey, the annual growth rate of the reed community at Osaka Nanko bird sanctuary was estimated to be 1,638.4 dry-g/m2/yr, the amount of carbon storage was estimated to be 691.4 g-C/m2/yr, and the amount of carbon sequestration was estimated to be 272.0 g-C/m2/yr.
