Stand structure and carbon storage in the oligohaline zone of the Sundarbans mangrove forest, Bangladesh

Abstract

A mangrove community along the oligohaline zone of the Sundarbans Reserve Forest (SRF), Bangladesh was selected to study stand structure, biomass accumulation, and carbon storage. Field data were measured from six plots of 2400 m 2 at three different locations. Species diversity and species wise contribution to total biomass carbon (TBC) were also analyzed. Heritiera fomes has maintained its dominance (53.8%, relative density) of the stand. The mean above-and below-ground biomass carbon stock of the mangrove community was 76.8 Mg ha¡1 and 41.1 Mg ha ¡1 , respectively. Avicennia officinalis contributed the highest TBC accumulation. Individuals of different mangrove species having diameter 9.99 cm constituted more than 72% of the mangrove stand but contributed less in carbon accumulation, representing only 15.6% of the TBC. While individuals having diameter in the 10-56 cm range constituted only 28% of stand density but contributed to high carbon accumulation, representing 84.4% of the TBC. Mangrove communities growing along the oligohaline zone of the SRF show high species richness and carbon stock, indicating their ecological significance, This needs to be considered in future decision making processes for the area as well as in understanding the role of SRF on mitigating the effects of climate change.

Effects of Tree Species Diversity and Stand Structure on Carbon Stocks of Homestead Forests in Maheshkhali Island, Southern Bangladesh

“…In our case, when tree height and DBH increased by one unit each, the biomass C stock increased by 11 and 3 Mg C ha -1 , respectively (Figures 7a and 7b). The importance of contribution of larger trees to the biomass C stock is in line with [24] who depicted that individuals with DBH of 10 -56 cm, constituting only 28% of stand density, contributed 84% of the total biomass C stock in mangrove forest.…”

“…C stocks were found to vary with land uses, including mangrove and coastal (99 Mg C ha -1 ; [22]), protected contiguous and fragmented (34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53) Mg C ha -1 ; [15]), bamboo (53 Mg C ha -1 ; [23]), hill (103 Mg C ha -1 ; [16]) and homestead (53 Mg C ha -1 ; [17]) forests. These C stocks have been found to be dependent on the stand structure (e.g., tree height, DBH, density, basal area) [24,25] and tree species [26,27], and stands with fast-growing tropical tree species having the highest forest C stocks (201 Mg C ha -1 ; [28]). Tree species diversity may increase above-ground biomass C stocks of tropical forests [29,30] .…”

Spatial and temporal dynamic of land-cover/land-use and carbon stocks in Eastern Cameroon: a case study of the teaching and research forest of the University of Dschang

“…However, in this previous study, they considered biomass of litter and herbaceous. Carbon stocks found in swamps were close to those of 117.98 ± 29.54 found by Kamruzzaman et al (2018) in mangrove communities in Bangladesh and are higher than those of 53.45 ± 43.72 reported by Kumar and Sharma (2015) in Balganga reserve forest in India.…”

Productivity of highland bamboo (Yushania alpina) across different plantation niches in West Amhara, Ethiopia

“…Forest stand structure is recognized as being of theoretical and practical importance in understanding and managing forest ecosystems (Tewari 2016). It is used to manipulate the management objectives following the establishment of a forest stand in order to understand productivity so that to estimate the products (Franklin et al 2002;Kamruzzaman et al 2018). Evaluation of site characteristics and their productivity on the growth response of bamboo is crucial to plan, implement, and improve the productivity for sustainable resource use (Mulatu and Fetene 2013).…”
