Nature in Papua New Guinea

Papua New Guinea contains lowland tropical forests, Highlands and alpine environments, savanna and grasslands, wetlands, rivers, karst landscapes, mangroves, seagrass beds, coral reefs and deep marine habitats across New Guinea, the Bismarck Archipelago, Bougainville and offshore islands. Its land and sea support birds-of-paradise, tree-kangaroos, cuscus, cassowaries and many reef and freshwater species. The national baseline remains incomplete because remote and under-surveyed areas have not been studied equally. More than 130 Key Biodiversity Areas have been identified, and the country's marine ecosystems form part of the Coral Triangle. Papua New Guinea has a formal but unevenly implemented conservation system. The Protected Areas Act 2024 provides for a Protected Area Network with national, regional, private, community and marine categories. Examples include national parks, national heritage sites, special management areas, national maritime sanctuaries, community conservation areas, Locally Managed Marine Areas and Wildlife Management Areas. The National Conservation Council and the Conservation and Environment Protection Authority, known as CEPA, support the national framework. Provincial and local-level governments, customary landowner groups and management committees also affect how individual sites operate. A protected area normally relies on a management plan, defined permanent or temporary zones, monitoring and local rules. The framework includes public review on a five-year cycle, conservation benefit-sharing and support for sustainable livelihoods. A 2017 PNG-METT assessment reviewed more than 57 protected areas and found fragmented effectiveness, limited finance and capacity, difficult access and frequent absence of government staff in areas that were often owned or managed by customary communities. Conditions therefore differ substantially between sites. Customary ownership is central to land and marine conservation. Customary landowners may control access, support stewardship, approve or reject activities affecting their rights and participate in benefit-sharing arrangements. Free, prior and informed consent is required when property rights are surrendered. Community conservation, customary stewardship and locally managed marine conservation can operate alongside formal protected-area registration, but their rules, responsible groups and legal force must be checked for the particular place. Local names include customary landowners, community conservation areas and Locally Managed Marine Areas; these terms do not describe one identical national procedure. Nature is used for customary subsistence harvesting, smallholder agriculture, hunting, forestry, mining, oil and gas, fisheries, aquaculture and tourism. Conservation conflicts can arise when logging or extractive projects affect forests, water or coastal ecosystems, when fishing becomes illegal or unsustainable, when endangered wildlife is hunted for bilas, or when shoreline clearing and marine pollution damage reefs. Disagreements may also concern consent, representation, benefit-sharing and the capacity to monitor or enforce rules. Sustainable-use principles do not remove the need to follow protected-area plans, environmental permits, fisheries rules and species protections. The Conservation and Environment Protection Authority handles environmental regulation and environmental permits for regulated development. The National Fisheries Authority, or NFA, deals with fisheries and marine-resource rules. The PNG Tourism Promotion Authority, or PNGTPA, promotes nature tourism, including trekking, birdwatching, diving, snorkelling, fishing, kayaking, surfing, caving and river or coastal exploration, with an emphasis on niche tourism and environmental and social sustainability. Access to a particular site may still depend on landowner or community consent, a management plan, local rules, a provider or guide, transport arrangements and seasonal conditions. Remote terrain and wet or dry season weather can change travel time and safety. Papua New Guinea has no single national admission tariff for nature sites and no universal public-access right or countrywide visitor permit that applies to every location. Fees may depend on the site, landowners, provider and transport. A CEPA project-permit fee is not the same as a visitor admission fee. Marine conditions, remoteness and seasonal weather also affect when a visit is practical. A site-specific check with the responsible authority, landowner group, community, provider or guide is needed before travel. CEPA environmental awareness work, NBSAP 2025–2030 capacity building and traditional ecological knowledge support conservation education and practice. NBSAP means the National Biodiversity Strategy and Action Plan. PNG-METT has also supported practitioner training. A formal nationwide pathway for nature education has not been verified. Earthquakes, volcanic eruptions, tsunamis, floods, landslides, cyclones, drought and El Niño or La Niña conditions can affect ecosystems and access; detailed emergency response belongs to disaster planning. Sea-level rise, coral bleaching and ocean acidification place additional pressure on coastal and marine habitats. Papua New Guinea has one UNESCO World Heritage property, Kuk Early Agricultural Site, which is cultural rather than natural. It has no inscribed natural World Heritage property. Seven natural or cultural landscape candidates appear on the Tentative List, but tentative status does not itself make a site a protected natural area. Nature protection, tourism access and heritage status therefore need to be checked separately.
