Mount Makiling


Site description (2001 baseline):

Site location and context
Mt Makiling is an isolated peak to the south of Laguna de Bay in southern Laguna Province, about 50 km south of Metro Manila. Although it only rises to just over 1,000 m and is located in a densely-populated part of Luzon, it still retains extensive forest cover. The forest is mainly lowland in type, with some montane forest around the peak above 900 m. The forest on most of the lower slopes has been cleared or degraded, but an area of good quality lowland forest remains around the botanic garden and the campus of the University of the Philippines Los Baños (UPLB). There are several types of agriculture on the slopes of Mt Makiling, including coconut plantations intercropped with coffees, bananas, and other commercial fruit trees; citrus orchards; and fruit plantations mixed with aroids, pineapples, and vegetables. The cultivation of these crops is encouraged by the proximity of the mountain to markets and its accessibility to wholesale buyers. The forests on Mt Makiling collectively perform various important ecological functions, including the prevention of soil erosion and acting as a sanctuary for wildlife. Mt Makiling is an important watershed, including as a source of the natural springs that are a major tourist attraction at Los Baños. A trail goes up the mountain from the UPLB campus, and the mountain is popular with tourists and birdwatchers.

Key biodiversity
Many of the restricted-range birds of the Luzon Endemic Bird Area have been recorded on Mt Makiling, and a few threatened species, including Philippine Eagle-owl. This relatively accessible site is popular with bird-watchers, and has been well studied by biologists from the nearby University of the Philippines Los Baños, and many of these species are known to occur in good numbers there.

Non-bird biodiversity: Threatened and poorly-known endemic threatened mammals recorded in the area include Luzon Broad-toothed Rat Abditomys latidens, Lowland Striped Shrew-rat Chrotomys mindorensis, Northern Luzon Giant Cloud Rat Phloeomys pallidus and Luzon Short-nosed Rat Tryphomys adustus. Large flying foxes Pteropus and Acerodon spp. have been observed flying over the forest canopy. The endemic Luzon Pygmy Fruit Bat Otopteropus cartilagonodus may be present at higher elevations on Mt Makiling. Amphibians recorded in the area now totals 26, out of which 14 are endemic to the Philippines. These endemics include the recently described Luzon Forest Frog Platymantis luzonensis and Diminutive Forest Frog Platymantis mimulus, and the poorly-known ranid, Limnonectes macrocephalus. Reptiles recorded in this IBA include endemic and rare species, such as the White-Spotted Anglehead Gonyocephalus semperi, Jagor’s Sphenomorphus Sphenomorphus jagori, Black-sided Sphenomorphus Sphenomorphus decipiens and Steere’s Sphenomorphus Sphenomorphus steerei. A total of 2,038 species of flowering plants has been recorded on Mt Makiling.

Pressure/threats to key biodiversity
Threats to the forests on Mt Makiling include the illegal conversion of forest to agricultural land and illegal settlement, and the area of land exploited by these upland settlers is expanding. The Institute of Forest Management and UPLB Administration are attempting to control the situation. The park is also a favorite destination of hikers and campers due to its proximity to urban centres. Rubbish and vandalism is very evident throughout the park especially in the camping and picnic areas. Settlers within the park, as well as people from the nearby villages, engage in bird trade and hunting.

Protected areas
This IBA includes Mt Makiling National Park (3,328.65 ha), which was declared by Proc. No. 552 on 23 February 1933 and Proc. No. 692 on 2 August 1960. This park is now under the jurisdiction of UPLB. Mt Makiling is proposed as a forest reserve under the NIPAS.
