Urban forest has a key role in mitigating the consequence of global climate
change. Along with natural forest, urban park has also a significant
contribution to carbon sequestration which yet not studied completely. This
study was conducted to estimate above and below ground carbon stock, tree
species diversity and soil organic carbon at Chandrima Uddan and Ramna Park
in Dhaka city. A total 46 plots were sampled to determine diameter at breast
height of trees, tree height and tree species diversity. Using allometric
equations and assuming C as 50% of biomass, the mean above and below
ground biomass carbon stock was found 122.19 Mg ha

in Chandrima Uddan
and 247.91 Mg ha

in Ramna Park. In total 506 trees were sampled and 48
different tree species were identified and recorded. The Shannon Wiener Index
was used to evaluate the tree diversity per plot. It ranged from 0 to 1.71 with a
mean value of 0.87 in Ramna Park and 0 to 1.33 with a mean value of 0.58 in
Chandrima Uddan. For the estimation of soil organic carbon (SOC), soil
samples were collected from two depths (5-10cm and 20-25cm) at two
different sampling sites of sampled plot. The mean value of SOC was found
28.82 Mg ha
-1
in Chandrima Uddan and 25.52 Mg ha
-1
in Ramna Park. Among
different relationships, the relationships between basal area and tree carbon
stock showed significant (P<0.05) and strongly positive correlation in both
parks. Therefore, the results of the study confirmed that the selected parks can
serve as a valuable ecological tool in terms of carbon sequestration, diverse tree
species and storage of soil organic carbon which have a key role in reducing
greenhouse gases and contributing to climate change mitigation. |
