Nature in Timor-Leste

Timor-Leste has a formal conservation system, but implementation remains fragmented and formal, municipal and customary approaches operate in parallel. The Ministry of Tourism and Environment, including the General Directorate of Environment and the National Directorate of Biodiversity, works with municipal authorities, sucos, traditional and community leaders, the Ministry of Agriculture and Fisheries and other public bodies. The national protected-area system includes terrestrial, freshwater, wetland, coastal, marine and mixed areas. Legal categories include wildlife sanctuaries, natural monuments, protected landscapes and nature reserves. Protected areas may be public, private, community-based, transboundary or provisional. A provisional classification can last for up to three years, while classification requires a government resolution, geographic delimitation, a management deadline and consultation with government, municipalities, non-governmental organizations and local or traditional leaders. Boundary determination and formal gazettement remain incomplete. The 2026 biodiversity strategy identifies 49 protected areas, including two national parks; an earlier baseline recorded more than 750 square kilometres of marine area and 4,247 square kilometres of terrestrial area. The national target for 2030 is effective conservation of at least 30 percent of terrestrial, inland-water, coastal and marine areas. Nino Konis Santana National Park includes Jaco Island, Lake Ira Lalaro, coastal reefs, forest and wetlands. Its objectives include habitat and species protection, marine protection, sustainable use of living resources, habitat recovery, research and sustainable local development. In 2026, UNESCO recognition covers the Nino Konis Santana Biosphere Reserve, which includes the park and surrounding buffer and transition areas. Subsistence hook fishing by Tutuala residents remains an exception in the Jaco Strait. Other protected places include Kay Rala Xanana Gusmão National Park and areas in Samba Sembilan and Liquiçá, Atauro and Manufahi. Timor-Leste records about 2,460 known species, including approximately 807 terrestrial plants, 264 marine fish, 69 terrestrial mammals, 28 marine mammals and more than 300 hard-coral species. Priority species include the Timor green pigeon, Timor imperial pigeon, Timor quail, yellow-crested cockatoo, Timor sparrow, Timor deer, McCord's snake-necked turtle, humphead wrasse, giant guitarfish, scalloped hammerhead shark and largetooth sawfish. Overexploitation, especially overfishing, forest degradation, uncontrolled burning, unsustainable agriculture, firewood collection, plastic and pesticide pollution, invasive species and sedimentation threaten habitats and species. Community forests, locally managed marine areas, open and closed areas, no-take zones, mangrove restoration and Tara Bandu can support conservation when their rules are agreed, understood and enforced. Nature contact such as trekking, birdwatching, snorkeling, diving and wildlife observation should follow protected-area zoning, signs, marked trails, ranger or local guidance and customary rules. Visitors should not disturb wildlife, coral or seagrass, hunt, bring pets into restricted areas or leave rubbish. Remote roads, four-wheel-drive sections, limited mobile coverage and seasonal floods or landslides affect access. Guide, boat, transport and accommodation costs vary, and remote services commonly require United States dollars in cash; no uniform national entry or diving-fee schedule was identified. Timor-Leste's Constitution recognizes a right to a healthy and ecologically balanced environment and a duty to protect it. Citizens and legal persons may participate in consultations and report suspected biodiversity harm or violations. Projects with possible environmental or social impacts require environmental licensing. Category A projects undergo an environmental impact assessment, category B projects undergo an initial environmental examination and category C projects follow a lower-tier procedure; public comments and monitoring form part of the process, while standard fees, processing times and appeal details vary or were not evidenced in the reviewed material. Drought, irregular heavy rainfall, flash floods, landslides, erosion, wildfire, heat, sea-level rise, storms and warming or chemical stress in coral habitats affect ecosystems and livelihoods. Saltwater crocodiles are a particular risk in southern coastal wetlands, where fishing, swimming and water collection expose people to attacks. Environmental education involves the General Directorate of Environment and the Environmental Education and Information Center through activities such as Green School, Blue Week, Ocean Tara Bandu, the Students' Ecological Oath, water and pollution experiments and national ecological competitions. Nature conservation therefore depends on connecting formal management, local knowledge, public participation, safer use and fair sharing of benefits.
