Valuing The Cost Of Interventions Through Mangrove Rehabilitation: The Case Of Panguil Bay, Philippines

Mangrove forests are extremely productive ecosystems that provide numerous goods and services both to the marine environment and the people. This study aimed to assess the mangrove forest situation of Panguil Ba and to value the costs of interventions. Specifically, it sought to determine the mangrove profile of Panguil Bay, assess the population density of the different mangrove species and assesses the performance of the interventions. To determine the population density of mangroves, the actual assessment was conducted through the transect-quadrat method in the mentioned barangays. The results revealed that mangrove forests in Panguil Bay are already in their alarming state. The population declined by more than 50% for 59 years caused by conversion to fishponds, built-ups, cultivated areas for agriculture and some become part of the sea. The government exerted its effort to rehabilitate the mangrove forests and spent P13,500 per hectare. However, the survival rate of planting was very low with only 29%. Only eight species of mangrove are found in Tangub City under the six families, five of which were included in the Red List of IUCN.
