Personnel of CENRO Catanauan discovered an inland wetland in the municipality of Mulanay, Quezon during the conduct of site assessment on areas covered by Presidential Proclamation No. 2152.

Based on the interview with the Brgy. Officials of Sto. Nino in Mulanay, Quezon, the wetland is home to Philippine wild duck (Anas luzonica), Philippine Sailfin Lizard (Hydrosaurus pustulatus) and Monitor Lizard (Varanus cumingi) as the said species were actually sighted feeding and swimming in the area. Aside from the said wildlife, there are also sightings of migratory birds such as white egret, herons, and kingfishers.

Personnel of CENRO Catanauan tracked the wetland and recorded its exact location and technical description using GPS. The wetland will be subjected for profiling to determine its characteristics and classification system based on the given criteria for the identification of wetlands critical to biodiversity conservation (DENR Memorandum Circular No. 1997-17). The criteria are in accordance with the objectives of the Philippine Wetland Action Plan.

Wetland ecosystem serves as a habitat of endemic wetland plants and animals including fishes. Despite its certain functions that make it important to society, wetlands are the least understood and have been traditionally regarded as wastelands. Thus, conservation measures for wetland ecosystems must be prepared and implemented to sustain the benefits that may be derived from it.
