Carbon Sequestration Potentials for Conservation of Sheikh Russel Aviary and Eco-Park, Rangunia, Chittagong

Abstract

The study investigates the carbon sequestration potential of tree species in the Sheikh Russel Aviary and Eco-Park, situated in diverse natural settings. Utilizing quadrate sampling, the study selected plot sizes of 26*26 m based on tree species diversity. Employing a Randomized Block design with nine blocks, three plots were laid out for each block, categorized as Top, Middle, and Bottom according to hill altitude. Soil samples were collected at depths of (0-15cm) and (15-35cm) for calculating soil organic carbon and moisture content through the loss of ignition method. Enumerating 781 trees from 27 families within 27 quadrates, the survey revealed total volume, basal area, biomass, and carbon sequestration potential, with Acacia auriculiformis displaying the highest Importance Value Index (IVI). Notably, Acacia auriculiformis, Tectona grandis and Gmelina arborea exhibited the highest carbon sequestration potentials, contributing significantly within specific diameter and height classes. The study further assessed soil organic carbon content and moisture levels, providing a comprehensive overview of the ecological contributions of the studied area.
