These unique attributes make Palawan not only a national treasure but also a crucial component of the global environmental landscape. Effective governance and stringent environmental laws are essential to conserving Palawan's ecological integrity for future generations. The province’s legal framework reflects a commitment to sustainable development, balancing economic growth with the imperative to protect its irreplaceable natural resources. The following sections will delve into the specific laws and regulations that govern environmental conservation in Palawan, highlighting their role in maintaining the province’s ecological balance and safeguarding its international heritage.
Palawan’s Environmental and Cultural Significance
Palawan is recognized nationally and internationally for its exceptional biodiversity, distinctive landscapes and seascapes, and living Indigenous cultures. Its environmental governance is shaped by a combination of international recognitions, national laws, provincial policies, protected-area systems, and science-based conservation designations.
Significant Environmental and Cultural Designations
UNESCO Palawan Biosphere Reserve (1990)
The entire Province of Palawan was recognized as a Biosphere Reserve under UNESCO’s Man and the Biosphere Programme in 1990. The designation recognizes Palawan’s globally important biodiversity and promotes an approach that combines environmental conservation, sustainable development, scientific research, and the well-being of local and Indigenous communities.
UNESCO World Heritage Sites
Palawan contains two natural properties inscribed on the UNESCO World Heritage List:
Tubbataha Reefs Natural Park — inscribed in 1993 and extended in 2009. Located in the Sulu Sea, the park protects globally significant coral reefs, marine species, and important breeding and nursery habitats.
Puerto Princesa Subterranean River National Park — inscribed in 1999. The park is recognized for its spectacular limestone karst landscape, underground river, intact forests, and complete mountain-to-sea ecosystem.
National Integrated Protected Areas System
Republic Act No. 7586, or the National Integrated Protected Areas System Act of 1992, established a national system for identifying, classifying, managing, and protecting ecologically important areas. It was strengthened by Republic Act No. 11038, or the Expanded NIPAS Act of 2018.
Several protected areas in Palawan form part of this national system, including Tubbataha Reefs Natural Park, Puerto Princesa Subterranean River National Park, El Nido-Taytay Managed Resource Protected Area, Malampaya Sound Protected Landscape and Seascape, Mount Mantalingahan Protected Landscape, Rasa Island Wildlife Sanctuary, and other ecologically important sites.
Strategic Environmental Plan for Palawan
Republic Act No. 7611, or the Strategic Environmental Plan for Palawan Act, establishes a comprehensive framework for the sustainable development of the province while protecting and enhancing its natural resources and environmentally sensitive areas.
The law created the Palawan Council for Sustainable Development, which provides policy direction and oversees the governance and implementation of the Strategic Environmental Plan in coordination with local governments, national agencies, communities, and other stakeholders.
Environmentally Critical Areas Network
The Environmentally Critical Areas Network, commonly known as ECAN, is the principal strategy for implementing the Strategic Environmental Plan. It establishes a graded system of protection and development control across Palawan’s terrestrial, coastal, marine, and tribal areas.
Through ECAN zoning, areas are classified according to their ecological sensitivity and appropriate uses. These include core zones, different categories of buffer zones, traditional-use areas, and multiple-use zones. The system is intended to guide land and resource use, development planning, environmental assessment, and conservation throughout the province.
Key Biodiversity Areas
Palawan contains numerous Key Biodiversity Areas, or places identified through scientific criteria as being especially important for the persistence of threatened, geographically restricted, or otherwise significant species and ecosystems.
Examples include Mount Mantalingahan, Rasa Island, Ursula Island, Malampaya Sound, and other terrestrial and marine areas supporting endemic and threatened wildlife. KBA recognition identifies sites of high conservation importance, but it does not automatically provide the same legal protection as designation under a national law.
Important Bird and Biodiversity Areas
Several areas in Palawan are recognized as Important Bird and Biodiversity Areas because they support globally threatened, restricted-range, endemic, migratory, or congregatory bird species.
These include areas associated with Rasa Island, Ursula Island, Busuanga, Puerto Princesa Subterranean River National Park, and other important habitats. This international recognition helps identify conservation priorities and supports efforts to protect the forests, wetlands, islands, and coastal ecosystems on which birds and other wildlife depend.
Coron Island Natural Biotic Area and Tagbanua Ancestral Domain
Coron Island is included in the Philippines’ UNESCO World Heritage Tentative List as the Coron Island Natural Biotic Area. Its limestone formations, forests, freshwater and brackish lakes, coastal ecosystems, and endemic wildlife contribute to its exceptional ecological and cultural value.
The island and its surrounding waters also form part of the ancestral domain of the Tagbanua communities of Coron. Their customary laws, traditional knowledge, and community-based management practices demonstrate the essential role of Indigenous Peoples in conserving natural resources while safeguarding cultural identity, livelihoods, and the right to self-determination.
A Shared Responsibility
These laws, recognitions, and conservation designations affirm Palawan’s exceptional ecological and cultural importance. They also carry a shared responsibility: government institutions, businesses, communities, civil society organizations, and citizens must ensure that development decisions respect environmental limits, Indigenous Peoples’ rights, scientific evidence, and the needs of future generations.
Together, these frameworks provide a foundation for protecting Palawan’s forests, waters, wildlife, ancestral domains, and communities while pursuing development that is lawful, inclusive, and genuinely sustainable.
Key Environmental Laws and Policies

The Palawan Council for Sustainable Development (PCSD) oversees the Strategic Environmental Plan (SEP) for Palawan, emphasizing sustainable development and biodiversity conservation. The SEP aims to balance economic growth with environmental protection through zoning regulations, resource management, and community involvement. Key components include protecting forests and marine ecosystems, promoting eco-friendly tourism, and ensuring the sustainable use of natural resources. The SEP also involves strict monitoring and enforcement to prevent illegal activities and degradation of Palawan's unique ecosystems.
NIPAS Act of 1992 (Republic Act No. 7586) establishes a legal framework for the protection and management of significant biodiversity areas in the Philippines, including those in Palawan. The law designates specific areas as protected, ensuring their ecological integrity is maintained through sustainable management practices. In Palawan, notable NIPAS sites include the Tubbataha Reefs Natural Park and the Puerto Princesa Subterranean River National Park, which are vital for conserving the province's unique biodiversity and supporting sustainable tourism and local livelihoods.
Palawan has taken a bold step to protect its environment and people by passing a 50-year moratorium on all large- and small-scale mining activities. This resource explains Provincial Ordinance No. 3646, series of 2025, exploring its legal foundation, scope, enforcement mechanisms, and its role in shifting the province toward sustainable agri-tourism. It also highlights the grassroots efforts and public support that fueled this landmark decision—marking a turning point in Palawan’s environmental governance.
The Indigenous Peoples Rights Act (IPRA) of 1997 (RA 8371) protects and promotes the rights of Indigenous Cultural Communities and Indigenous Peoples (ICCs/IPs) in the Philippines. It recognizes ancestral domain rights, ensures indigenous communities' rights to self-governance, cultural integrity, and customary laws, and mandates the state to uphold their participation in development decisions. The law establishes the National Commission on Indigenous Peoples (NCIP) to oversee implementation and resolve disputes. IPRA emphasizes environmental protection, sustainable resource use, and guarantees ICCs/IPs' free, prior, and informed consent regarding activities affecting their ancestral territories.
