To obtain a reliable basis for biodiversity conservation and management, basic taxonomic assessment is very important. Marine benthic macrophytes play a very significant role on primary production in marine ecosystems. Taxonomic assessment of marine benthic macrophytes was conducted last January 2016 in Cagdianao, Claver, Surigao Del Norte, Philippines. Data was collected following the line transect methods described by the Aquatic Plant Monitoring and Assessment Methods of Aquatic Ecosystem Restoration Foundation (AERF), with some modifications. Identification of seaweeds and seagrass was done using published taxonomic references and others were from online data base. A total of thirty four (34) species of marine macrophytes belonging to fifteen families were collected and identified at the shallow coastal waters of Cagdianao, Claver, Surigao Del Norte, Philippines. Results shows that station 1 had the most number of individuals suggesting that it might be the most preferable habitat for seagrass and seaweeds followed by station 3, station 4 and study station 2. Economic development activities such as road and building constructions, industrialization, coastal runoffs were all possible threats that could affect the marine ecosystems including the marine benthic macrophyte community which play a crucial role in marine food chain.
