Luzon rainforest

The Luzon rainforest is a moist broadleaf forest that contains the lowlands (below 1000 m) of Luzon and the montane rainforests located on a several volcanic and non-volcanic mountains of the island. The rainforest encompasses about 95,571 square kilometers (36,900 sq mi) out of the 109,965 sq kilometers (42,458 sq mi) of total area of the island of Luzon. Luzon is the largest and most northern island of the Philippines, located in the western Pacific Ocean. Though it is the most extensive rainforest ecoregion of the Philippines, very little of the original rainforest remains. Considered a part of the Luzon rainforest ecoregion are the Batanes and Babuyan Islands to the north, Catanduanes and Polillo Islands to the east, and Marinduque to the southwest. The status of this area is critical/endangered.

Luzon has never been connected to mainland Asia. Even when glacial advances during the caused sea levels to fall over 100 meters worldwide, this only connected Luzon to the modern islands of Polillo, Marinduque, and Catanduanes. At least 15 million years ago, friction between the Australian and Asian tectonic plates and volcanic activity created parts of the Luzon highlands, which over the next 10 million years morphed into their modern form. This long period of isolation and complex internal geography is a primary cause for the great biodiversity and high degree of endemism found on the island of Luzon.
