Mount Mandalagan
Also known as: Mandalagan massif
Definition
Mount Mandalagan is a large mountain massif in the northern part of Negros island, Philippines, rising within Negros Occidental as part of the volcanic chain that includes Mount Silay and, farther south, Kanlaon. An eroded dormant volcano exceeding two thousand meters, it lies inside the Northern Negros Natural Park, one of the last significant forest blocks of northern Negros and a stronghold for critically endangered island wildlife.

Also Known As
- Mandalagan massif
Examples and Analogies
- Quiet elder volcano: Mandalagan is to Kanlaon what a weathered, dormant ancestor is to an active relative in the same family — same volcanic lineage, gentler reputation.
- Negros water tower: Like other highland parks in the Visayas, it functions as the region’s water tower, feeding rivers that irrigate the island’s sugarlands below.
Usage Scenarios
1. Trekking through Patag
Hikers ascend Mandalagan’s slopes via the Patag valley trail in Silay City, camping in montane forest below the summit ridges.
2. Biodiversity Research and Conservation
Biologists survey the park for Negros-endemic birds and mammals, including bleeding-heart doves and hornbills dependent on the remaining old-growth patches.
3. Watershed Protection Programs
Local government and environment units run reforestation and patrol programs to secure the catchment supplying northern Negros communities.
Strategies
- Treks coordinate with the protected area office and local guides at Patag, pairing patrols with visitor management
- Reforestation uses native species to rebuild habitat corridors between Mandalagan and Kanlaon forest blocks
- Conservation groups engage sugar-industry stakeholders whose upland practices affect the park’s margins
Security and Safety Measures
- Leeches, rain, and cold nights above the mossy line require proper gear and seasoned guides
- Permits and registration through the protected area management board keep treks accounted for in emergencies
- Patrols guard against illegal logging and hunting that degrade the habitat core
Historical Context
Mandalagan belongs to the Negros volcanic arc, and its deeply dissected profile records long dormancy and erosion rather than recent eruption. During the twentieth century the northern Negros forests shrank before logging and cane-field expansion, concentrating conservation attention on the Mandalagan–Silay highlands. In 2005 the area was formally established as the Northern Negros Natural Park under the national protected area system, since reinforced by the Expanded NIPAS Act of 2018, making the massif’s forests a legally shielded refuge for species that once ranged across the whole island.

Challenges and Controversies
Forest Encroachment
Kaingin (slash-and-burn farming), illegal cutting, and land-conversion claims along park boundaries continue to fragment habitat.
Boundary Conflicts
Overlapping ancestral and private claims around the park periodically complicate enforcement and co-management agreements.
