caption_attribution_description: English: Sierra Madre is the most lush green vegetation found in the Northern Philippines. You can view the great sight of the mountain in Quirino, Isabela and Aurora provinces. You may also cross the Sierra Madre mountain range when travelling from Quirino province to Aurora. One of the protected areas of DENR because of its rich flora and fauna.
context_page_description: The Sierra Madre a 690 km is the longest mountain range in the Philippines. Through the north-south direction from Santa Ana in the province of Cagayan to the north and Bondoc Peninsula in Quezon to the south, the mountains form the eastern backbone of Luzon Island, the largest island of the archipelago. It is bordered by the Pacific Ocean to the east. The Pacific coast of Luzon along the Sierra Madre is less developed as the lofty and continuous mountains form a bold and almost inaccessible shore, exposed to the full force of the northeast monsoon and the waves of the Pacific Ocean. Some of communities east of the mountain range and along the coast are so remote they are only accessible by plane or boat.
  The country's largest protected area, the Northern Sierra Madre Natural Park, is situated at the northern part of the range in the province of Isabela. The park is in the UNESCO tentative list for World Heritage List inscription. Environmentalists, scholars, and scientists have been urging the government to include the other parks within the Sierra Madre mountains for a UNESCO site that would encompass the entire Sierra Madre mountain range from Cagayan to Quezon province.
context_section_description: Two ecoregions cover the Sierra Madre. The Luzon rain forests cover the lower slopes of the range, and are characterized by dipterocarp trees. The Luzon montane rain forests cover the portions of the range above 1000 meters elevation, and are characterized by laurel forests of oak and laurel trees.
