Abstract

Carbon stock assessment quantifies carbon stored in ecosystems, which is vital for understanding their role in sequestering carbon dioxide, informing sustainable land management crucial for human activities and climate change mitigation. Employing purposive sampling to evaluate the biomass, carbon (C) stock, and carbon dioxide (CO2) sequestered in Daclan Communal Forest, using non-destructive methods, it informs climate change monitoring, mitigation, and adaptation strategies while promoting proper forest management and sustainable development. Additionally, it underscores the potential economic value derived from the forest's carbon pools. The methodologies used include measuring trees at diameter breast height (DBH) and sampling herbaceous vegetation, litter, and soil for C content determination, using eight (8) 30m by 30m plots to gather the data and samples. The Communal Forest boasted substantial biomass totaling approximately 262 Mg ha-1, comprising 182.17 Mg ha-1 of carbon and sequestering 671.26 Mg ha-1 of CO2. This abundance holds a significant economic value estimated at Php3,038,237.09. The figures highlight the considerable role of the Communal Forest in sequestering atmospheric carbon, indicating its potential for carbon crediting and trading. Therefore, collaborative efforts from Local Government Units (LGUs), community residents, and relevant organizations are imperative for the enhancement, sustainability, and conservation of these forests.
