Forests of the Philippines: From Sierra Madre to Mt. Apo — A Conservation Portfolio

The Philippines hosts one of Earth's most biodiverse—and threatened—forest estates. Once 90% forested; now ~24% (7M hectares), fragmented across 7,600+ islands. Here are the flagship forest protected areas:

1. Northern Sierra Madre Natural Park (Luzon)

359,486 ha. Largest protected area in PH. Old-growth dipterocarp, montane, mangrove. Philippine eagle, Isabela oriole, Northern Sierra Madre forest monitor. Cagayan, Isabela, Quirino.

2. Mt. Apo Natural Park (Mindanao)

54,974 ha. Highest peak (2,954 m). Tropical rainforest → montane → summit grassland. Philippine eagle, waling-waling orchid, endemic rodents. Davao, Cotabato.

3. Mt. Kitanglad Range Natural Park (Mindanao)

47,270 ha. 2nd highest (2,899 m). Mossy forest, grasslands. Tarsier, flying lemur, Kitanglad shrew-mouse. Bukidnon.

4. Puerto Princesa Subterranean River National Park (Palawan)

22,202 ha. UNESCO WHS. 8.2 km navigable underground river. Karst limestone, cave fauna, Philippine pangolin, Palawan peacock-pheasant.

5. El Nido-Taytay Managed Resource Protected Area (Palawan)

90,321 ha. Limestone cliffs, mangroves, lowland forest, coral reefs. Marine-terrestrial continuum. Palawan hornbill, mouse-deer.

6. Siargao Island Protected Landscape & Seascape (Surigao del Norte)

278,914 ha. Mangroves (largest in PH), coastal forest, cloud forest. Surfing mecca (Cloud 9). Pygmy forest (bonsai-like trees on ultramafic soil).

7. Subic Bay Forest Reserve / Pamulaklakin (Zambales)

Former US naval base. Secondary forest recovery. Long-tailed macaque, civet, raptors. Aeta ancestral domain.

8. Marikina Watershed Forest Reserve (Rizal/Metro Manila)

2,600 ha. Critical water source for Manila. Reforestation focus. La Mesa Watershed adjacent.

9. Bataan National Park (Bataan)

23,688 ha. WWII history (Death March). Dipterocarp, molave, mangrove. Bataan Peninsula biodiversity corridor.

10. Tubbataha Reefs Natural Park (Sulu Sea)

97,030 ha. UNESCO WHS. Marine park—atoll reefs, 600+ fish, 360 coral, sharks, turtles, seabirds. No land forest, but included for completeness.

What "Amazon Rainforest Philippines" Means

There is no "Amazon" in the Philippines. The Amazon is South American. The term sometimes appears in clickbait or confusion. The Philippines has Philippine tropical rainforests—distinct, endemic-rich, Wallacea-influenced.

Conservation Status

• Deforestation drivers: illegal logging, mining, agribusiness (oil palm, banana), infrastructure, settlement.
• ENIPAS Act (2018) strengthened 94 protected areas.
• Indigenous Peoples' Rights Act (IPRA) — ancestral domain titles overlap forests; key to stewardship.
• Reforestation: National Greening Program (mixed results; survival rates low).

Philippine forests are not a monolith. They're an archipelago of evolutionary experiments—each mountain, each island, a separate story. Losing one is losing a world.
