Overview
The Northern Negros Natural Park is a significant protected area situated in the northern mountainous forest region of the island of Negros in the Visayas. It serves as the largest watershed in the province of Negros Occidental and acts as the primary water source for seventeen municipalities and cities, including the Bacolod metropolitan area. The park spans across five municipalities and six cities within Negros Occidental, covering the local government units of Murcia, Salvador Benedicto, Talisay, Silay, Enrique B. Magalona, Victorias, Cadiz, Sagay, Toboso, Calatrava, and San Carlos. It is governed by the Department of Environment and Natural Resources and remains an active conservation zone.
Historical Establishment and Expansion
The protected area was first established as a forest reserve on 28 April 1935 through Administrative Act No. 789, which was signed by Governor-General Frank Murphy. At its inception, the reserve spanned 107,727 hectares. On 7 August 1946, the Northern Negros Forest Reserve was reduced to its present area of 80,454.5 hectares with the signing of Proclamation No. 798 by President Manuel Roxas. In 2005, the protected area was converted into a natural park under the National Integrated Protected Areas System (NIPAS) Act by virtue of Proclamation No. 895 signed by President Gloria Arroyo.
History
The protected status of the Northern Negros Natural Park evolved over several decades, transitioning from a colonial-era forest reserve to a formal natural park under Philippine law. The area was first designated as a forest reserve on 28 April 1935, established through Administrative Act No. 789 signed by Governor-General Frank Murphy. This initial designation covered a vast expanse of 107,727 hectares, securing the northern mountainous forest region of the island of Negros as a critical ecological zone.
Post-War Adjustments
Following World War II, the boundaries of the reserve were adjusted to refine its administrative scope. On 7 August 1946, President Manuel Roxas signed Proclamation No. 798, which reduced the Northern Negros Forest Reserve to its present area of 80,454.5 hectares. This reduction helped define the specific geographic limits of the protected zone, which would later become the province's largest watershed and a vital water source for seventeen municipalities and cities, including the Bacolod metropolitan area.
Conversion to a Natural Park
The final major step in the park's legal evolution occurred in 2005. The protected area was officially converted into a natural park under the National Integrated Protected Areas System (NIPAS) Act. This conversion was enacted through Proclamation No. 895, signed by President Gloria Arroyo, solidifying its status as a key component of the Department of Environment and Natural Resources' portfolio in the Visayas region.

Geography and Location
The Northern Negros Natural Park is situated in the northern mountainous forest region of the island of Negros, within the Visayas region of the Philippines. This protected area serves as a critical geographical feature for the province of Negros Occidental, functioning as the largest watershed in the region. The park’s location is central to the hydrological stability of the northern part of the island, providing essential water sources for seventeen municipalities and cities. This includes the Bacolod metropolitan area, which relies on the park’s catchment for its water supply. The terrain is characterized by highland interior forests that define the northern landscape of Negros Occidental.
Administrative Boundaries
The park’s boundaries are extensive, spanning across multiple local government units in Negros Occidental. According to the ground truth data, the park is spread over five municipalities and six cities. The specific municipalities included in the park boundaries are Murcia, Salvador Benedicto, Talisay, Silay, Enrique B. Magalona, Victorias, Cadiz, Sagay, Toboso, Calatrava, and San Carlos. These local government units share jurisdiction over the protected area, which covers a significant portion of the northern interior. The administrative spread reflects the park’s role as a shared natural resource for both urban centers like Bacolod and surrounding rural municipalities. The Department of Environment and Natural Resources oversees the management of this expansive area, ensuring the preservation of the watershed for the benefit of the entire northern Negros region.
Biodiversity and Flora
The Northern Negros Natural Park forms a critical component of the Negros–Panay Biogeographic Region, a distinct ecological zone characterized by high levels of endemism and diverse forest ecosystems. This protected area serves as a vital sanctuary for the island's remaining primary and secondary forests, supporting a complex web of flora and fauna that define the northern Visayan landscape. The park's topography, ranging from lowland dipterocarp forests to montane vegetation, provides varied habitats essential for the survival of species found nowhere else in the Philippines.
Flora and Forest Composition
The park is dominated by dipterocarp forests, which are the backbone of the tropical rainforest ecosystem in the region. These tall, emergent trees form the canopy that regulates the microclimate and supports epiphytic growth throughout the reserve. Among the notable plant species is Cycas vespertilio, a rare cycad species that thrives in the specific soil and moisture conditions found within the park's boundaries. The presence of such specialized flora indicates the health and relative stability of the forest floor and understory environments. The extensive tree cover also plays a crucial role in soil retention and water filtration, directly impacting the watershed quality for the seventeen municipalities and cities that rely on the park as a primary water source.
Endemic Fauna
The biodiversity of the Northern Negros Natural Park is highlighted by several endemic animal species that are increasingly threatened across the Visayas. The Visayan spotted deer, one of the smallest deer species in the world, finds refuge in the dense undergrowth and secondary growth areas of the park. This species is particularly sensitive to habitat fragmentation, making the contiguous forest cover of the reserve essential for its continued survival. Additionally, the Negros shrew, a small mammal endemic to the island, inhabits the leaf litter and forest floor, serving as a bioindicator of the ecosystem's health. These animals, along with various bird and reptile species, contribute to the ecological richness that the Department of Environment and Natural Resources aims to preserve through ongoing conservation efforts under the NIPAS Act.
Why it matters
The Northern Negros Natural Park holds a position of exceptional ecological rarity within the Philippine archipelago. It is recognized as one of only two remaining lowland forests on the island of Negros, a distinction that underscores the severity of deforestation that has historically affected the region. This scarcity of lowland forest cover makes the park a critical biological refuge, preserving biodiversity that would otherwise be fragmented or lost in the surrounding agricultural and urban landscapes of the Visayas.
Beyond its botanical significance, the park functions as the largest watershed in the province of Negros Occidental. This hydrological role is vital for the regional economy and public health. The protected area serves as the primary water source for seventeen municipalities and cities. This service area includes the Bacolod metropolitan area, the capital city of the province, which relies on the park’s catchment for its municipal water supply. The integrity of the forest cover directly influences the volume and quality of water flowing into the rivers that feed these communities.
The scale of the park supports this extensive watershed function. Established as a forest reserve in 1935 and later reduced to its present area of 80,454.5 hectares in 1946, the park covers a substantial portion of the northern mountainous region. The conversion of this area into a natural park in 2005 under the National Integrated Protected Areas System (NIPAS) Act formalized its protection status. This legal framework, established through Proclamation No. 895 signed by President Gloria Arroyo, ensures that the land use remains focused on conservation rather than intensive extraction, thereby sustaining the water yield for the dependent populations.
The park’s location across multiple local government units, including Murcia, Salvador Benedicto, Talisay, Silay, Enrique B. Magalona, Victorias, Cadiz, Sagay, Toboso, Calatrava, and San Carlos, highlights its cross-jurisdictional importance. Managing such a large and dispersed protected area requires coordination among these municipalities and cities. The Department of Environment and Natural Resources oversees the park, ensuring that the ecological functions that support the seventeen beneficiary localities are maintained. The preservation of this lowland forest is therefore not merely an environmental concern but a critical infrastructure asset for the water security of western Negros.
Recent events and conservation challenges
Conservation efforts for the Northern Negros Natural Park have faced significant political and economic pressures, particularly regarding land use conversion. In 2014, officials from the municipality of Salvador Benedicto proposed converting 500 hectares of the park’s forest land for investment purposes. This proposal aimed to attract developers to the area, leveraging the park's strategic location within the province’s largest watershed. The potential conversion sparked immediate debate over the balance between economic development and ecological preservation in the Visayas region.
Political Opposition
The proposal encountered strong resistance from provincial leadership. Governor Alfredo Marañon opposed the conversion of the 500-hectare tract, citing the critical role the Northern Negros Natural Park plays as a water source for seventeen municipalities and cities, including the Bacolod metropolitan area. The park, which was reduced to its present area of 80,454.5 hectares in 1946, serves as a vital buffer for the region’s hydrological stability. Governor Marañon’s stance highlighted the risks of fragmenting the protected area, which had been established as a forest reserve in 1935 and later converted into a natural park in 2005 under the National Integrated Protected Areas System (NIPAS) Act.
Legislative Efforts
At the national level, Representative Julio Ledesma IV engaged in legislative efforts to address the conservation challenges facing the park. His interventions focused on reinforcing the legal protections established by Proclamation No. 895, signed by President Gloria Arroyo. The representative’s work aimed to ensure that any future development within the park’s boundaries would undergo rigorous environmental impact assessments, preserving the integrity of the 80,454.5-hectare area managed by the Department of Environment and Natural Resources. These efforts reflect the ongoing tension between local economic ambitions and the broader ecological needs of Negros Occidental.
