Three (3) major coastal and marine habitats: coral reef and associated reef fish species, seagrass beds, and mangrove ecosystems in the municipalities of Viga and Bato, Catanduanes were assessed by the Technical Team of the Coastal Resources and Foreshore Management Section (CRFMS) of the Conservation and Development Division (CDD) together with some technical staff of the Provincial Environment and Natural Resources Office (PENRO) Catanduanes. Sampling protocols based on the Guidelines on Biodiversity Assessment and Monitoring System (BAMS) for Coastal and Marine Ecosystems were followed. Likewise, key components for biodiversity such as species composition, richness and abundance were recorded to assess the status and extent of cover and conditions of the aforementioned habitats. The activity is part of the technical assistance to the LGU for the implementation of Coastal and Marine Ecosystems Management Program (CMEMP) of the DENR.
