Biodiversity Facts

Status and trends of biodiversity, including benefits from biodiversity and ecosystem services The content of this biodiversity profile is still draft. The text below has been prepared by SCBD and remains subject to final approval by the Party concerned.

The Philippines is one of 18 mega-biodiverse countries of the world, containing two-thirds of the earth’s biodiversity and between 70% and 80% of the world’s plant and animal species. The Philippines ranks fifth in the number of plant species and maintains 5% of the world’s flora. Species endemism is very high, covering at least 25 genera of plants and 49% of terrestrial wildlife, while the country ranks fourth in bird endemism. The Philippines is also one of the world’s biodiversity hotspots with at least 700 threatened species, thus making it one of the top global conservation areas. The national list of threatened faunal species was established in 2004 and includes 42 species of land mammals, 127 species of birds, 24 species of reptiles and 14 species of amphibians. In terms of fishes, the Philippines counts at least 3,214 species, of which about 121 are endemic and 76 threatened. In 2007, an administrative order issued by the Department of Environment and Natural Resources established a national list of threatened plant species, indicating that 99 species were critically endangered, 187 were endangered, 176 vulnerable as well as 64 other threatened species.

Biodiversity

This unique biodiversity is supported by a large variety of ecosystems, landscapes and habitats, most of which are also greatly threatened by human activities. According to the FAO definition, the Philippines has 7.2 million ha of forest ecosystems, comprising approximately 24% of the total land area. It is however estimated that, between 2000 and 2005, the Philippines lost 2.1% of its forest cover annually, representing the second fastest rate of deforestation in Southeast Asia (second to Myanmar) and seventh in the world. The country’s agricultural ecosystem is also noteworthy. The Philippines is part of the center of diversity of rice, coconut, mung bean, taro and yam, as well as the center of origin and diversity of bananas in Southeast Asia. Yet this agricultural biodiversity is nowadays experiencing general decline, as is the land area devoted to these activities.

The trend is similar for inland water biodiversity, with findings indicating a decreasing trend in water quality, fish, biodiversity and cultural value in the country’s largest lake (Laguna de Bay) and its tributary rivers. The Philippines presents unique coastal, marine and island biodiversity. It is indeed located within the Coral Triangle, at the center of highest marine biodiversity. A study conducted in 2005 noted that there is a higher concentration of species per unit area in the country than anywhere in Indonesia and Wallacea. Yet this ecosystem is also greatly at risk. While the 2005 review of the state of the marine and coastal environment indicated an increase in the mangrove cover, reef cover, seagrass cover and fishery production are nowadays decreasing substantially.
