Abstract
Kaliwa watershed in the province of Rizal and Quezon is a site for pilot implementation of an improved watershed management plan in the Philippines. As part of the key biophysical resource assessment for the watershed carbon stocks in above-ground biomass, necromass and soil pools in different forest land uses were determined using field measurements. The total C stored in the different land uses surveyed in the Kaliwa Watershed is estimated at 2.65 Megatons, 76% of which is held in secondary forests, and 14% and 10% in brushlands and grasslands, respectively. In all land uses, the largest portion of C is held in the soil. The low C density estimates (secondary forest-121.21 Mg/ha; brushland-74.27 Mg/ha, and grassland 57.56 Mg/ha) indicate that substantial degradation of forest resources has occurred through time. activities to enhanced the watershed's potential to serve as C sink were identified, including forest protection, reforestation of grassland areas and establishment of agroforestry and community-based forestry projects.
