Conservation Efforts In Cat Ba National Park

Cat Ba National Park protects much of the wild heart of Cat Ba Island, from limestone forests and hidden valleys to caves, mangroves and the waters around the island. It is also home to one of the rarest primates on Earth, the Cat Ba langur. Behind the green scenery is decades of conservation work by park rangers, scientists, local communities and partners, and every visitor can play a small part in it.

In this guide, the Haiphong Adventure team explains why Cat Ba National Park matters, the main conservation efforts happening on the island, how local villages are involved and simple ways to visit responsibly. Figures and programmes change over time, so treat the details as a general overview (updated October 2026).

Why Cat Ba National Park Matters

Cat Ba National Park was established in 1986 and is often described as one of the first national parks in Vietnam to protect both land and sea ecosystems. Together with the surrounding islands, the Cat Ba Archipelago was recognised as a UNESCO Biosphere Reserve in 2004, and in 2023 it became part of the Ha Long Bay and Cat Ba Archipelago World Heritage Site.

• Limestone karst forest. Rare forests growing on steep rock, with plants adapted to thin soils.
• Wildlife. Primates, bats, birds, reptiles and many insects, including species found almost nowhere else.
• Caves and valleys. Hidden habitats that shelter wildlife and hold human history.
• Coast and sea. Mangroves, beaches, coral and seagrass areas around the island.

The Cat Ba Langur A Symbol Of Conservation

The golden-headed or Cat Ba langur lives only on Cat Ba Island. Its dark body and pale golden head make it easy to recognise, but very few people ever see one in the wild.

From near extinction to slow recovery

Hunting and habitat loss in the past pushed the species to the edge. By the early 2000s, only a few dozen individuals were thought to survive, making it one of the most endangered primates in the world. Since then, protection work has helped the population grow slowly, although it is still very small and classed as critically endangered.

How the langur is protected

• Long-term projects. A dedicated Cat Ba langur conservation project has worked with the park and international zoo partners since around 2000.
• Guards and monitoring. Local guardians watch over key habitats and record sightings.
• Strict protection zones. Some areas where langurs live are closed to tourists to avoid disturbance.
• Education. Schools and villages learn why the langur matters and how to protect it.

Please do not try to find langurs on your own or ask boat drivers to approach their cliffs. The best way to help is to respect closed areas and support responsible operators.

Protecting The Forest Ecosystem

Most of the park’s work happens quietly in the forest. Rangers and staff focus on keeping the habitat healthy so that plants and animals can recover on their own.

Ranger patrols

Forest rangers patrol trails and remote valleys to prevent illegal logging, hunting and trapping. They also watch for forest fires in the dry season.

Replanting and restoration

Degraded areas near the park edges are replanted with native species, helping to connect fragments of forest and reduce erosion on steep slopes.

Research and monitoring

Scientists and park staff survey plants, birds, bats and primates to understand how populations are changing and where protection is most needed.

Caring For The Sea Around Cat Ba

Conservation on Cat Ba does not stop at the shoreline. The waters around the island, including Lan Ha Bay, are part of the same fragile system.

• Coral and seagrass. These shallow habitats shelter young fish and are sensitive to pollution and anchors.
• Mangroves. They protect the coast from storms and provide nursery areas for marine life.
• Managing floating farms. In recent years, local authorities have worked to reorganise and regulate floating fish farms in the bays to reduce pollution.
• Clean-up efforts. Local groups, schools and tour operators join beach and bay clean-ups to reduce plastic waste.

Rules and projects in the bays change from time to time, so follow the instructions of your boat crew and local guide.

How Local Communities Help

Many people live inside or next to the park, and their support is essential. Viet Hai village, reached by trail or by boat, is a good example of how village life and conservation can work together.

• Eco-friendly homestays. Small guesthouses give families an income from visitors instead of from forest resources.
• Local guides. Villagers who know the forest share their knowledge and help visitors stay on safe trails.
• Farming in harmony. Small gardens and rice fields are kept at a scale that fits the landscape.
• Community awareness. Education programmes explain the value of the langur and the forest.

Challenges Facing Cat Ba National Park

Conservation on Cat Ba is a success story in progress, but the park still faces real pressures.

How To Visit Cat Ba National Park Responsibly

Your choices as a visitor make a difference. These simple habits help protect the park.

1. Stay on marked trails. Shortcuts damage plants and cause erosion.
2. Never feed wildlife. Feeding changes animal behaviour and can make them sick.
3. Carry your rubbish out. Bring a small bag for wrappers and bottles.
4. Keep noise down. Quiet visitors see more birds and disturb less.
5. Respect closed zones. Some areas are closed to protect langurs and other wildlife.
6. Use local guides. They know the safe routes and the rules, and your fee supports local families.
7. Choose refillable bottles. Cut down on single-use plastic during your trip.
