Mt Apo (Davao & Cotabato)

Mount Apo is a large solfataric, potentially active stratovolcano in the island of Mindanao, Philippines. With an elevation of 2,954 metres (9,692 ft) above sea level, it is the highest mountain in the Philippine Archipelago and is located between Davao City and Davao del Sur province in Region XI and Cotabato province in Region XII. The peak overlooks Davao City 45 kilometres (28 mi) to the northeast, Digos City 25 kilometres (16 mi) to the southeast, and Kidapawan City 20 kilometres (12 mi) to the west.

The first two attempts to reach Mt. Apo’s summit ended in failure: that of Jose Oyanguren (1852) and Señor Real (1870). The first recorded successful expedition was led by Don Joaquin Rajal in October 10, 1880. Prior to the climb, Rajal had to secure the permission of the Bagobo chieftain, Datu Manig. It is said that the Datu demanded that human sacrifice be made to please the god Mandarangan. Fortunately, the datu agreed to waive this demand, and the climb commenced on October 6, 1880, succeeding five days later. Since then, numerous expeditions followed. These and more are described in colorful narrations by Fr. Miguel Bernad, S.J. On May 9, 1936, Mount Apo was declared a national park by President Manuel L. Quezon. A note on the etymologies: Mt. Apo is said to be named after a nobleman named Apong, who was killed while mediating the battle between two suitors of his daughter Saribu. Another proposed origin of the name is from the word Apo itself, which in Filipino tongues means “master” or “grandson."

Mount Apo Natural Park

On May 9, 1936, Mount Apo was declared a national park with Proclamation no. 59 by President Manuel L. Quezon, followed by Proclamation no. 35 of May 8, 1966 then Proclamation no. 882 of September 24, 1996. On February 3, 2004, the approval of Republic Act no. 9237 established Mount Apo as a protected area under the category of natural park with an area of 54,974.87 hectares (135,845.9 acres); with two peripheral areas of 2,571.73 hectares (6,354.9 acres) and 6,506.40 hectares (16,077.7 acres) as buffer zones, provided for its management and for other purposes.

Although a declared a Natural Park, the current climbing trails are littered with rubbish by irresponsible climbers, opening paths for soil erosion across the already denuded mountain sides. Some mountain and social climbing groups conduct climbs after the Holy Week/Easter, the peak climbing season, to clean the affected areas.

UNESCO World Heritage list

The Department of Environment and Natural Resources (DENR) submitted Mount Apo on December 12, 2009 for inclusion in the UNESCO world heritage list. The mountain is considered by DENR as the center of endemism in Mindanao. It has one of the highest land-based biological diversity in terms of flora and fauna per unit area. It has three distinct forest formations, from lowland tropical rainforest, to mid-mountain forests, and finally to high mountain forests.

A portion of the eastern slopes are also within the scope of the UNESCO Hydrology Environment Life and Policy (HELP) Network. The Davao HELP Network is focused on building collaboration among watershed stakeholders.

In March 2015, it was taken out from the UNESCO List of Tentative Sites due to the dramatic changes (such as logging, intrusion of companies and urban and agricultural landscape, exploitation, and poaching, among others) it experienced which does not constitute the UNESCO documents that describes the park. Better conservation and a change in the content of documents was recommended by UNESCO.

Climate

A dry Season of March and April

Mt. Apo generally enjoys tropical rainy climate. It falls under the Type IV climate under the modified corona's classification wherein rainfall is relatively distributed throughout the year. Mean monthly temperature ranges from a low 26.4 o C during January to 27.9 o C during April. Monthly relative humidity ranges from 78% during March and April and 82% during June and July.

Flora and fauna

The mountain is home to over 272 bird species, 111 of which are endemic to the area. It is also home to one of the world's largest eagles, the critically endangered Philippine eagle, which is the country’s national bird.

Bodies of water

Lakes - There are four major lakes in Mt. Apo . Popular of these are Lake Agco, used to be called "The Blue Lake" and Lake Venado, a famous mountaineers camping site and a stopover towards the peak. Lake Macadac and Lake Jordan are found in the summit grassland.

Rivers - Mt. Apo has 19 major rivers and 21 creeks draining its 8 major watersheds (PASAlist.1992). Out of the 19 major rivers, only two has studies as reported by SEA-BMB consultants for the Mt. Apo Geothermal Project Environmental Impact Assessment 1991. According to the report, there are two river ecosystems draining the geothermal site namely: (1) Marbel-Matingao river ecosystem- characterized by narrower river channels at highly elevated areas, much faster water flow, clearer water and rock boulder-rich water beds. The aquatic organisms in the area have expectedly lower biological productivity and species diversity. The report also concluded that this river ecosystem provides much less economic and commercial value for its biological production. The study identified 12 species of fish caught in the area; (2) Kabacan River- Pulangi River ecosystem- characterized by a much wider channels at flat areas, relatively much slower water flow, highly turbid waters and sandy mud river beds.

Biological Features

Grasslands - The grasslands are characterized by the dominance of Cogon grass Imperata cylindrica and Saccharum spontaneum. Other grasses and ferns also thrive, especially along banks of creeks, streams, and rivers and on steep slopes
