Species and Ecosystem Diversity in Protected Areas
Mt. Apo Natural Park (MANP)
The flora include 629 species under 148 families of vascular and non-vascular plants. Five hundred
seventy two species belong to 124 families of ferns and angiosperms, while 57 species belong to
24 families of bryophytes or mosses.
Among the vascular plants in the area, Moraceae, represented by the genus Ficus, has the highest
number of known species. This particular group of plants is very important to the economy of the
forest for they provide food to many species of birds and mammals. Most fruit-eating birds feed on
Ficus fruits, particularly on the species bearing small reddish fruits which are quite abundant during
summer.
Ficus and other small trees such as Leucosyke, Nauclea, Macaranga, Homolanthus, and Dillenia
thrive in secondary forests at elevation of 300-500 m.a.s.l. such as in the Baratacab and Sibulan
areas. Dipterocarp species like Dipterocarpus, Shorea and Pentacme dominate the vegetation at
elevations of 650-1000 m.a.s.l. such as in Tibulo and Todaya. However, the dipterocarps assume
shorter heights and become co-dominant with other smaller trees and shrubs such as Lithocarpus,
Laportea and Areca at higher elevations of 1400 -1600 m.a.s.l. such as in Mainit-Kulan. At
1800-2000 m.a.s.l., particularly at Meran Baclayan, Agathis, Lithocarpus, Cinnamomum and
gymnosperms are the dominant species. At the crater lake in Cirribal, Rhododendron, Vaccinium,
Gleichenia and Polypodiaceae species were found to be most abundant along with bryophytes.
Ferns and orchids are common as herbaceous component and as epiphytes.
Among the high value species of trees in the area are the almaciga or Agathis philippinensis and
the dipterocarp species Shorea polita and Vatica mangachapoi. These tree species are threatened
due to overlogging. The world famous Vanda sanderiana or waling-waling and the rattan species
Plectocomia elmiri used to abound in the primary forests of Mt. Apo. However, these species can
no longer be found in their natural habitats because of over collection.
Six endemic plant species are restricted to Mt. Apo. These were identified under the families (1)
Lauraceae (Alseodaphne philippinensis); (2) Urticaceae (Cypholophus microphyllus) at an altitude
of 1800 m.a.s.l.; (3) Fagaceae (Lithocarpus submonticulus) at 17000 m.a.s.l.; (4) Nepenthaceae
(Nepenthes copelandii) in thickets at 2400 m.a.s.l. and (5) Piperaceae (Piperomia elmeri and P.
apoanum) at 800-1200 m.a.s.l.
A total of 227 vertebrates species belonging to 69 families of amphibians, reptiles birds and
mammals have been recorded in Mt. Apo. Likewise, 118 species of butterflies belonging to 69
families are recorded in the area.
Of the birds reported, most species are widely distributed and can be found throughout the
Philippines such as the blue shortwing, Brachypteryx montana. The Philippine eagle,
Pithecophaga jefferyi, the Philippine trogon, Harpactes ardens, and the yellow-bellied whistler,
Pachycephala philippinensis, are species recorded in Luzon, Samar, Leyte and Eastern Mindanao.
The fly-catchers, Eumyias panayensis, and Ficedula westermanni are reported in Luzon, Mindoro,
Negros, Panay and Mindanao. F. westermanni can also be found in Palawan. The strong-billed
shrike, Lanius validirostis, can be observed in the highlands of Mindoro, Luzon, and Mindanao,
while the Philippine bullfinch, Pyrrhula leucogenys, occurs in the highlands of Luzon and Mindanao
only. The presence of L. woodi, R. goodfellowi, E. payanensis, F. hyperythra, R. nigrocinnamomea
and H. cinnamomeus were also noted in the primary forest area.
The Mt. Apo myna Basilornis miranda, the Apo lorikeet Tricoglossus johnstoniae, the cinnamon bird
Hypocryptadus cinnamoneus, and the bagobo babbler, Leonardina woodi, and the black and
cinnamon fantail are among the Mindanao endemics in MANP. These species are believed to have
evolved on Mt. Apo before spreading to surrounding peaks such as in Katanglad, Malindang, and
Matutum.
The Philippine eagle, P. jefferyi, is by far the most important bird species in Mt. Apo This bird is not
found elsewhere in the world and has become the symbol of Philippine conservation efforts.
Widespread destruction of its habitat and over collection is driving this species to extinction.
Mammalian species include shrews and gymnures, bats, rats, squirrels, ungulates, civet cats and
deers. The families Pteropidae and Muridae are the most represented. The pteropid bats are
common in Mt. Apo, particularly Cynopterus brachyotis, Haplonycteris fischeri and Rousettus
amplexicaudatus. Of the mammals identified, only four are Mindanao endemics. These are
Apomys insignis, Urogale everetti, Sundasciurus philippinensis and Podogymnura truei. The
Philippine gymnure, P. truei, which belongs to family Erinacidae, was believed as restricted to Mt.
Apo until it was collected in Mt. Kitanglad. The deer species, Cervus mariannus apoensis is the
most threatened mammal in the area.
With regard to reptiles and amphibian species, they are either widely distributed in the Visayan
and Mindanao Regions or occur throughout the country. Among the reptiles is the tree skink,
Lipinia quadrivitata, which is also found in Borneo. As for amphibians, the pelobatid species
Megophrys hasselti and M. stejnegeri are not only found in the Indo-malayan Region, but they
also have considerable altitudinal ranges. They can be found from almost sea level to an elevation
of 2000 meters. Important reptile species occurring in Mt. Apo include the burrowing skinks of the
Genus Brachymeles and the Cuming's eared skink, Otosaurus cumingi. The latter is rare and the
largest in its family. The monitor lizard, Varanus salvator, is one of the species used as food.
Important amphibian species include the Philippine woodland frog, Rana magna, the broad hearted
forest frog, Leptobrachium hasselti, the horned forest frog, Megophrys monticola, the Mueller's
toad, Ansonia muelleri, the Mindanao toad, Pelophryne brevipes, the montane narrow-mouthed frog,
Oreophryne annulatus. R. magna is considered an endangered species throughout the country
because it is widely collected for food. Moreover, rate of population increase of the species is slow
for it requires unpolluted cool water for successful breeding. It also has a relatively long tadpole
stage making it vulnerable to changes in the forest environment. L. hasselti is considered a true
forest frog because it cannot survive in open areas. This species is considered rare because of its
cryptic, or secretive behavior, similar to M. monticola.
The butterflies in the area are numerous in terms of number of species. They occur in a wide range
of habitat, from cultivated lands to grasslands, from second growth to primary forest. Among the
species commonly found are Eurema hecabe, Graphium sarpedon, Papilio rumnzovia, P.
aquamemnon and Mycalesis tagala sermirasa. Five endemic species of butterflies are known.
These are: (1) Parantica schoenigi, (2) Delias lecicki, (3) D. schoenigi, (4) D. apoensis, and (5) D.
woodi. Of the five, D. woodi and D. schoenigi have wider vertical distribution range. They were
observed between approximately 800 and 2400 m.a.s.l. All species are usually found close to
bodies of water.
