This legislation marked the first formal recognition of the region's biological value, designating it as a national park to safeguard its unique ecosystems. The park is globally recognized for hosting the largest remaining population of the critically endangered tamaraw, a dwarf buffalo endemic to Mindoro. The preservation of this species is the primary driver of the area's conservation status and international attention.

ASEAN Heritage and Global Recognition

The ecological importance of Mount Baco and its surrounding park extends beyond national borders. In 2003, the Association of Southeast Asian Nations (ASEAN) listed the Mounts Iglit–Baco Natural Park as one of its four heritage parks in the Philippines. This designation highlights the park's role in regional biodiversity conservation, recognizing it as a key area for maintaining the biological wealth of Southeast Asia. Furthermore, the park's global significance was underscored in 2006 when it was nominated to the Tentative List of UNESCO World Heritage Sites. This nomination reflects the international community's interest in preserving the unique montane forests and endemic species found in the interior of Mindoro.

Expanded Protection under ENIPAS

Conservation efforts for Mount Baco have evolved over time to address changing environmental pressures. In 2018, the park was officially designated as a "Natural Park" under Republic Act No. 11038, also known as the Expanded National Integrated Protected Areas Systems (ENIPAS) Act of 2018. This legislative update increased the protected area to 106,656 hectares, providing a broader buffer for the ecosystems surrounding Mount Baco and Mount Iglit. The expansion aims to enhance the resilience of the habitat for the tamaraw and other endemic species, ensuring long-term ecological stability. The Biodiversity Management Bureau oversees these efforts, managing the park as an active protected area to maintain its status as a Key Biodiversity Area.

What are the main threats to the tamaraw population?

The tamaraw, a critically endangered dwarf buffalo endemic to the island of Mindoro, faces severe survival pressures within the Mounts Iglit–Baco Natural Park (MIBNP). As the park is home to the largest remaining population of this species, the conservation status of the tamaraw is inextricably linked to the ecological integrity of the 106,656-hectare protected area designated under the Expanded National Integrated Protected Areas Systems (ENIPAS) Act of 2018. Despite its status as an ASEAN Heritage Park since 2003, the tamaraw subpopulations continue to contend with persistent anthropogenic and environmental threats.

Poaching and Direct Exploitation

Poaching remains one of the most immediate dangers to the tamaraw. The animals are often hunted for their meat, which is consumed locally, and for their horns, which are prized in traditional medicine and as decorative trophies. The accessibility of certain forest fringes allows hunters to penetrate deep into the core zones of the park. The pressure is exacerbated by the species' relatively small body size and distinct appearance, making them recognizable targets for local hunters who may not always distinguish between the tamaraw and the more common carabao or wild water buffalo. Conservation efforts by the Biodiversity Management Bureau focus on patrol intensity, yet the vastness of the 106,656-hectare area makes complete surveillance challenging.

Habitat Loss and Fragmentation

Habitat loss driven by traditional land-use practices significantly impacts tamaraw subpopulations. Although the park was initially established in 1970 covering 75,445 hectares, the expansion to 106,656 hectares under Republic Act No. 11038 aimed to consolidate fragmented forest patches. However, encroachment by small-scale farmers and settlers continues to reduce the available grazing and breeding grounds. The conversion of lowland forests into agricultural land creates edge effects, exposing tamaraws to predators and human disturbance. This fragmentation isolates smaller subpopulations, reducing genetic diversity and making the species more vulnerable to stochastic events such as forest fires or disease outbreaks.

Traditional Land-Use and Human-Wildlife Conflict

Traditional land-use practices, including shifting cultivation and livestock grazing, introduce competition for resources. Cattle and carabaos brought into the park by local communities can transmit diseases to the tamaraw and compete for forage. The proximity of human settlements to the park boundaries in Calintaan and surrounding municipalities increases the frequency of human-wildlife interactions. These interactions often result in the tamaraw being perceived as pests or prey, further intensifying the pressure on their numbers. Effective conservation requires balancing the livelihood needs of the local communities with the strict protection measures necessary to sustain the tamaraw population within this critical Mindoro ecosystem.
