Abstract

This study establishes the optimum thresholds and rating scales to evaluate the ecological integrity of Pasonanca Natural Park protected area in Zamboaga City, Philippines. Six indicators representing four key eco-hydrological attributes of sustainable water supply namely vegetation and soil at the riparian buffer zone, the hydrology and water quality of the stream, were assessed. Tree basal area was found to be high ranging from 56.08m ha to 65.46 m ha in undisturbed sites. These values are higher than other tropical forests in Southeast Asia. Total organic carbon and total nitrogen were at critical levels. Mean streamflow was significantly declining at 0.101 m s yr (p
