Estimation of Biomass and Carbon Storage in Trees of the Char Kukri Mukri Mangrove Forest in Bhola District, Bangladesh

Abstract

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.
