Four Bangladeshi villages were chosen at random to represent a total of 64 home gardens.The study’s objective was to evaluate the variety of tree species and the carbon store in the tree biomass on Char Island, both above and below groun. The Shannon Wiener index was used to evaluate the variety of tree species, and allometric equations were used to estimate the carbon stock, with the assumption that the stock represented 50% of the carbon in the tree biomass. The findings indicated that home garden ecosystems could store an average of 18.00 Mg of carbon per hectare, ranging from 1.66 Mg of carbon per hectare to 58.93 Mg per hectare and tree species diversity ranged from 0 to 1.84 with a mean value of 1.05 where most abundant was Eucalyptus camaldulensis (44.21%) which stored the most C (33.62Mg ha-1) followed by Moringa oleifera (29.37 Mg ha-1) in tree biomass. The study provides a evidence of tree diversity and carbon storage in char island.
