Basaw Lake, with geographic location of 17˚ 36’ 12.2” to 09.9” latitude and 121˚ 49’ 21.1” to 50’ 37.9” longitude, with surface area of 15.6ha is being eyed as the next eco-tourism site of Penablanca, Cagayan, Northern Philippines. This study was undertaken to assess the biological status of Basaw Lake. Rapid biodiversity assessment using transects, maps, and quadrat methods were used. Findings revealed a total of 21 faunal species fish (6), shellfish (8), shrimp (1), crab (1), turtle (1) and birds (4) on site. Collected mollusks were classified into families Planorbidae, Ampullariiddae, Cyclophoridae, and Thiaridae. Fishes were classified into families Anabantidai, Cichlidae, Clariidae, Gobiidae and Opichthydae. Families of collected crustaceans were Palaemonidae and Potamidae while birds were Anatidae, Meropidae, Apodidae, and Accipitridae. There were also a total of 15 floral species- trees (13), palm (1), and aquatic plant (1). Trees were classified into families Dipteroceae, Ebinacea, Rubiaceae, Myrcinaceae, Euphorbiaceae, Clusiaceae, and Araliacea; Palm under Malvaceae and aquatic plant under Nelumbonaceae. Zooplankton findings showed 17 species belonging to 15 genera, 11 families and 5 orders. Order includes Phyllopoda (4), Calanoida (3), Cyclopoida (4), Monogononta (4), and Bdellodea (2). Intensive survey should be continuously conducted to document all the species present including endemics within the area as basis for sustainable ecotourism development.
