The Sierra Madre is a mountain range in the Philippines. It is located along the north-eastern coast of Luzon Island, running north/south. Quezon National Forest Park is situated in the range.[1]


The Sierra Madre is the longest mountain range in the Philippines. The range starts in the north in the province of Cagayan and ends in the south in the province of Quezon, just east of Laguna de Bay. To the west as it reaches the province of Nueva Vizcaya to form the Caraballo Mountains, with which it connects with the Cordillera Central range.

The range's highest point is unclear, and several peaks claim this title. Mount Anacuao (Aurora) stands at 6,069 feet (1,850 m), while Mount Cetaceo (Cagayan) is of similar altitude. However, an expedition in April 2012 to Mount Guiwan (Nueva Vizcaya) preliminarily measured an altitude of 1,915 m on the summit.[2] Ecoregions in the range are in the Tropical and subtropical moist broadleaf forests (lower) and Tropical and subtropical coniferous forests (higher) biomes.

Endemic species[edit]

In the forest, in April 2010, the endemic lizard species Northern Sierra Madre Forest monitor lizard - Varanus bitatawa (common name: Butikaw) was described to science, although the Aeta and Ilongot indigenous peoples have known and used it as a food source.

Human activities[edit]

Lower portions of the Sierra Madre, with habitat damage from logging and charcoal-making.

The Sierra Madre mountain range forest habitat is threatened by human activities. Settlers living at the lower portions of the slopes generally are supported by work in logging and charcoal-making. Some portions of the forest cover are already second growth forest.
