Increased levels of global atmospheric carbon dioxide (CO₂) and further consequences of climate change derived more research efforts to emphasize the actual role of the ecosystems of higher significance in this task. Mangrove ecosystem received a great interest in the demonstration of its potential to sequester atmospheric CO_2. Sampling process from the sediment of mangrove ecosystem extended some 600 km along the Egyptian western coast of Red Sea, starting from Abu Monquar Island (27.216250° N, 33.876288° E) at the north near Hurghada to Sharm El-Madfa’a (22.895165° N, 35.717757° E) near the Egyptian–Sudanese frontiers. This work compares the pure population of Avicennia marina (Forssk.) Vierh. and Rhizophora mucronata, Lam. as well as the mixed population of both species. Mean values of dry bulk density (DBD) were 1.2 ± 0.02, g cm⁻³ for pure A. marina, 0.8 ± 0.06 g cm⁻³ for pure R. mucronata, and 0.7 ± 0.04 g cm⁻³ for mixed sites. In addition, the values of mean soil organic carbon (SOC) were 10.2, 51.7 and 89.0 g C kg⁻¹ for pure A. marina, pure R. mucronata and mixed sites, respectively. On the other hand, the mean values of soil organic carbon pool (SOCP) were 258.0, 604.7 and 1049.3 Mg C ha⁻¹ for pure A. marina, pure R. mucronata and mixed sites of both species, respectively. The carbon sequestration potential (CSP) of pure A. marina, pure R. mucronata, and mixed sites of both species were 0.8, 2.2, 3.4 Mg C ha⁻¹ year⁻¹, respectively.

全球大气二氧化碳 (CO ₂ )水平的增加和气候变化的进一步后果导致了更多的研究工作，以强调在这项任务中具有更高重要性的生态系统的实际作用。红树林生态系统在展示其封存大气 CO _{2 的}潜力方面引起了极大的兴趣。红树林生态系统沉积物的采样过程沿埃及红海西海岸延伸了约 600 公里，从阿布蒙夸尔岛 (27.216250° N, 33.876288 ° E) 在北部靠近 Hurghada 到 Sharm El-Madfa'a (22.895165° N, 35.717757° E) 靠近埃及-苏丹边境。这项工作比较了Avicennia marina (Forssk.) Vierh的纯种群。和红树， 我是。以及两个物种的混合种群。干堆积密度（DBD）的平均值分别为1.2±0.02，克厘米^-3纯A.码头，0.8±0.06克厘米^-3纯R. mucronata，和0.7±0.04克厘米^-3混合位点。此外，纯A. marina、纯R. mucronata和混合地点的平均土壤有机碳 (SOC) 值分别为 10.2、51.7 和 89.0 g C kg ^-1。另一方面，纯A. marina、纯R. mucronata的土壤有机碳库 (SOCP) 平均值分别为 258.0、604.7 和 1049.3 Mg C ha ^-1和两个物种的混合地点，分别。纯A. marina、纯R. mucronata和两种物种的混合位点的碳封存潜力 (CSP) 分别为0.8、2.2、3.4 Mg C ha ^-1 年^-1。
