Ecoregions in the Philippines
The
The Philippines was never connected to mainland
The
- Greater Luzon included Luzon, Catanduanes, Marinduque, Polillo, and several small islands.
- Greater Mindanao included Samar, and adjacent small islands.
- Greater Palawan included Palawan, Balabac, Busuanga, Culion, Cuyo, and adjacent small islands.
- Greater Negros–Panay included Cebu, and Masbate.
- Greater Sulu included the most of the Tawi Tawi to Jolo.
These formerly-linked islands each constitute a separate ecoregion, as does Mindoro, which remained separate from the rest, along with a few smaller islands, notably Camiguin, Sibuyan, and Siquijor.
Each group of islands that were linked by land bridges in the ice ages also constitutes a separate faunal region. The lack of a land bridge to the Asian continent prevented most of the Asian megafauna, including elephants, rhinoceros, tapirs, tigers, leopards, and gibbons, from reaching the Philippines, although they do inhabit the adjacent Indonesian islands of Sundaland, which were formerly linked to the Asian continent by lowered sea levels.
The other main factor that defines the Philippine ecoregions is elevation; the high mountains of Luzon and Mindanao host distinct montane rain forest ecoregions. The mountains of Luzon are also home to the Luzon tropical pine forests.
