The estimation of biomass and carbon stored by the trees in the Char Kukri-Mukri mangrove forest ecosystem of Bhola district of Bangladesh, was conducted during 2023 to 2024. The total recorded values of AGTB, BGTB, TTB, and TCS 145.3 tonh^-1, 29.06 tonh^-1, 174.36 tonh^-1, and 63.21 tonh^-1 in site-1; 671 tonh^-1, 134.2 tonh^-1, 805.2 tonh^-1, and 291.88 tonh^-1 in site-2; 252.6 tonh^-1, 50.52 tonh^-1, 303.12 tonh^-1, and 109.88 tonh^-1 in site-3; 378.9 tonh^-1, 75.78 tonh^-1, 454.68 tonh^-1, and 164.82 tonh^-1 in site-4; 394.9 tonh^-1, 78.98 tonh^-1, 473.88 tonh^-1, 171.78 tonh^-1 in site-5; 452.1 tonh^-1, 90.42 tonh^-1, 542.52 tonh^-1, and 196.66 tonh^-1 in site-6; 308.1 tonh^-1, 61.62 tonh^-1, 369.72 tonh^-1, and 134.02 tonh^-1 in site-7; 634.2 tonh^-1, 126.84 tonh^-1, 761.04 tonh^-1, 275.88 tonh^-1 in site-8. The total values of aboveground tree biomass (AGTB) of selected sites were found to show a range between 145.3 tonh^-1 and 671 tonh^-1. The maximum AGTB value 671 tonh^-1 was recorded from site-2, whereas the minimum AGTB value of 145.3 tonh^-1 was recorded from site-1. Similarly, the total values of belowground tree biomass (BGTB) of selected sites were found to show a range between 29.06 tonh^-1 and 134.2 tonh^-1. The maximum BGTB value 134.2 tonh^-1 was recorded from site-2, whereas the minimum AGTB value of 145.3 tonh^-1 was recorded from site-1. The values of TCS of selected sites were found to show a range between 63.21 tonh^-1 and 291.88 tonh^-1. The maximum TCS value 291.88 tonh^-1 was recorded from site-2, whereas the minimum TCS value of 63.21 tonh^-1 was recorded from site-1. As a coastal mangrove ecosystem, Char Kukri-Mukri possess high amount of biomass which indicates accumulation of good amount of carbon. This is a highly productive ecosystem that plays critical role to protect and stabilize the coastal mangrove zones of Bangladesh.
