Abstract


Mt. Tabayoc, in Kabayan, Benguet, is the second highest mountain in Luzon and the fifth in the Philippines. The meaning of the name, in the native tongues, is “basin”, alluding perhaps to the four lakes in its base: Lakes Tabeo, Incolos, Latep-ngapos and Ambulalacao. The present study was done to identify the diversity of planktons thriving in the identified lakes and correlate this with the physico-chemical properties in order to assess the water quality of these lakes. Water samples were collected from the four lakes and phytoplanktons were counted using Neubauer slide and verified by Dr.Luisito Evangelista, Director Botany Department National Museum. In Lake Tabeo most species found was Gleocapsa punctata, Chlorella vulgaris for Lake Incolos , Pinnularia sp. for Lake Latep-Ngapos and Nitzchia sp. in Lake Ambulalacao. Diversity indices showed that using Shannon-Weiner Lake Tabeo has the most diverse species yielding 2.6504 and in Pielou’s Evenness Lake Incolos has the highest computed value 0.4915. Lake Tabeo is highly diverse among the four lakes correlating it with Diversity indices with Physico-Chemical parameters.
